Latest GRUENCY Research for WS.COMPUTER
Cooling that tunes itself.
How we measure and tune GPU cooling in a workstation. A thermal model of an RTX 5090 over both fan sets and the power limit, built from measurements on our own test machine, then turned into the control law for WS.Sensor — so every workstation runs at the quietest settings that keep it within its temperature limits, fully automatically.
To our knowledge, no published work fits such a model over both fan sets of a high-power graphics card and uses it, with a fan-noise model, to choose settings within a noise budget.
Hot-spot temperature of the RTX 5090 over GPU-fan and case-fan speed at 575 W, from the model fitted to the measured grid. Arrows: direction of fastest cooling, −∇T.

“I'm extremely happy with my experience with WS.COMPUTER. The workstation is very professionally built, everything feels high quality, and the whole process from ordering to delivery was smooth and straightforward.”
I'm extremely happy with my experience with WS.COMPUTER. The workstation is very professionally built, everything feels high quality, and the whole process from ordering to delivery was smooth and straightforward. The computer arrived very well packaged and was easy to get up and running, even without much hardware experience on my side.
Customer service has also been excellent after the purchase, always responsive, helpful and clear whenever I've had any questions. Overall I couldn't really be happier with the workstation or the service and would happily recommend WS.COMPUTER to anyone looking for a high-end custom workstation.

“Still running silent and smooth since 2019. No issues. That quad 4090 setup is awesome for running local LLMs these days.”
Still running silent and smooth since 2019. No issues. That quad 4090 setup is awesome for running local LLMs these days.
Lately I've been testing a range of local language models, mostly Qwen3.8 27B: very small and fast, it runs on a single RTX 4090 or even smaller cards. As the flagship I run Qwen3.8 Next at Q4, which usually needs 115 GB but allocates to system RAM very well. So the machine runs it at full throttle: all 96 GB of VRAM, including a 256k context window, plus 40 GB of system RAM.
Qwen3.8 Next runs at 57 tokens per second, which is very, very fast for a local model on consumer GPUs.

WS.COMPUTER, Built to Last, Designed to Impress!
Sturdy, reliable, high-end, and built for the long run. It's rare to find all these qualities in one machine, but WS.COMPUTER delivers on every front.
I've had my rig for close to a decade, and it's been nothing short of phenomenal. Custom-built to suit my requirements and budget, it's easily one of the best decisions I've ever made. Nearly ten years without a single issue speaks volumes about the quality and reliability of their builds.
Honestly, my machine isn't just a PC — it's a flex! Even after all these years, it continues to impress.
If you're looking for a dependable, high-quality custom PC that's built to last, WS.COMPUTER is a name I can confidently vouch for.

Every WS.COMPUTER workstation ships with a 2-year warranty on parts and labour, backed by each manufacturer’s own warranty — up to 12 years.
Every component is also covered by its manufacturer’s full warranty. Terms and length depend on the component — see the table below.
2 years on the whole workstation. Up to 12 years on parts. Lifetime on the chassis.
Every WS.COMPUTER workstation carries a two-year warranty on parts and labour,
counted from delivery. Components with a longer manufacturer term keep it — up to 12 years
on power supplies — and we handle every claim for you for the full term. Technical support
is unlimited for the life of the machine.
In the first year we also cover shipping: replacement parts go anywhere at our cost, and within
the EU and the UK we collect and return the whole machine. The details are in the table below.

Coverage
What's covered — and what isn't
Covered
Manufacturing defects in any component
Failure under normal operating conditions
Premature wear that prevents intended function
Performance below the manufacturer's published spec
Stability issues we can reproduce in our lab
Dead on arrival — replaced or refunded in full
Pre-installed OS licence issues (Windows activation, etc.)
Labour to diagnose, repair and re-test the system
Not covered
Damage from manual overclocking beyond stock voltages
Failure caused by third-party parts you installed yourself
Cosmetic wear (scratches, dust, fan grilles)
Software issues unrelated to our pre-installed OS
Data loss — we always recommend backups
Use in environments outside spec (extreme temperatures, dust, humidity)
Filing a claim
How a warranty claim works
Email service@ws.computer with your order number and a short description of the issue.
We respond within one business day with next steps. We always diagnose remotely first, and ask for
hardware only when a hardware fault is confirmed.
Tell us what's happeningEmail service@ws.computer with your order number, photos or video if relevant, and what you've already tried. We don't make you fill in a form.
Remote diagnosis (when possible)For software, drivers and configuration issues we connect via secure remote session and resolve in place — no shipping required.
Replacement part or RMAUsually we send the replacement part. If the whole machine has to come back, we issue an RMA number and packaging instructions; in the first year within the EU and the UK we also send a pre-paid label.
Diagnosis and repairWe log your unit on arrival, run a full diagnostic, repair or replace failing parts, and re-run our standard tests.
Return shipped & trackedRepaired system ships back insured and tracked — at our cost in the first year within the EU and the UK, otherwise at yours. Average turnaround is 3–7 business days from receipt.
One contact for every claim
You never call a manufacturer's hotline yourself. If your graphics card fails eight months in, we file the RMA with the manufacturer and send you a replacement at our cost.
Out of warranty
After two years
Manufacturer warranties that run longer continue (power supplies up to 12 years, cooling 6, drives 5,
memory up to lifetime), and we keep handling those claims for free. Repairs and upgrades outside warranty
follow our fixed-price service menu — see
Service & Repair.
And our included support — email and phone help with drivers, BIOS updates, configuration tweaks,
general usage questions — never expires. That's free for the lifetime of the machine.
Still have a question?
We answer every email within one business day. You talk directly to the team that built your machine.
Your workstation ships in custom-cut foam, triple-wall corrugate and a GPU brace that absorbs transit shock. Insured for full value, signature on delivery, tracking from the moment we hand it over.
Packaging
Each workstation is packed by hand
A workstation isn't a box of accessories — it's a multi-kilo machine with a vertically-mounted GPU
that hates transit shock. We pack every WS.COMPUTER build the same way the components arrive from
their manufacturers: custom foam, double-walled corrugate, and a brace that takes the load off the
PCIe slot during transport.
Triple-wall corrugate
3-layer outer box rated for 60 kg and stacking pressure well beyond what carriers do in transit.
Custom-cut foam inserts
Closed-cell foam machined to your case shape. The system can't move inside the box.
GPU transit brace
Foam-blocked support under the graphics card prevents PCIe slot stress and sag during shipping.
Shock-watch label
External impact indicator on every box — you'll see immediately if the carrier dropped it.
ESD-safe wrap
Static-shielded bag around the system before foam, protecting against electrostatic discharge.
Photo proof of packing
You receive photos of your machine being packed, sealed and labeled before it leaves our bench.
Why this matters
A high-end GPU weighing 1.8 kg, mounted vertically on a PCIe slot, is the single most fragile
point in any modern workstation during transport. Most builders ship a system in a single-wall
box with bubble wrap and call it a day. We don't.
Carriers
Who ships your workstation
We use premium courier services exclusively. No economy ground, no general post. Workstations
always go insured for full declared value, with signature on delivery.

Customs & duties
For shipments outside the EU, customs duties and import VAT are paid by the recipient. We declare
full value on the invoice — under-declaring is illegal and we won't do it. The carrier collects
duty on delivery, or invoices it to your nominated broker.
After your order ships
What happens once it's on the truck
Tracking link sent immediatelyThe moment the carrier scans your package, you receive an email with a live tracking link and estimated delivery date.
Photo proof of packagingSent in the same email — you see exactly how your workstation was packed before it left our bench.
Delivery window the day beforeMost carriers give a 2–4 hour delivery window the day before. We forward it to you the moment we get it.
Signature required on deliveryThe driver hands the package to a real person who signs for it. No "left at door" — workstations are too valuable.
Inspect within 24 hoursOpen and visually inspect within one business day of delivery. Any visible transit damage must be reported within 48 hours.
If something looks wrong on arrival — crushed corner, broken shock indicator, anything — don't power
the system on. Photograph the package and email service@ws.computer
immediately. We file the carrier claim and ship a replacement that day.
Still have a question?
We answer every email within one business day. You talk directly to the team that built your machine.
Email us at info@ws.computer
Not what you expected? We'll make it right.
14-day no-questions returns for personal customers, and a fast RMA process for any defect — DOA replacements ship the same day we receive the unit.
Submit a request
Start your RMA online
Skip the email back-and-forth — fill in the short form below and you'll get a confirmation
email with your RMA number within a minute. Our service team responds within one business day.
We never share your information. See our terms for details.
Your rights
Two return paths, depending on who you are
EU consumer law and B2B contract law work differently — so we run two separate return policies.
We always tell you up front which one applies to you.
Personal customers (B2C)
14-day no-questions return from delivery date
Full refund of the system price
Original packaging required
Buyer pays return shipping unless DOA
Refund within 5 business days of receipt
Custom-built configurations: still returnable, but a 10% restocking fee applies
Business customers (B2B)
EU 14-day distance selling does not apply to B2B sales
Defects: full warranty cover via RMA process below
Wrong order or our error: free return + full refund or replacement
Buyer's remorse: case-by-case exchange against credit
Restocking fee: 15% on opened, 25% on configured-to-order
Custom configurations are non-returnable except for defects
Polish consumer law (Ustawa o prawach konsumenta z 30 maja 2014 r.) and EU Directive 2011/83/EU
govern personal returns. Business returns fall under the Polish Civil Code and standard B2B
contract terms.
DOA & defects
Dead on arrival? We replace it. Same day.
If your workstation arrives dead, damaged, or fails within the first 14 days from a manufacturing
defect, we treat it as DOA. You get a full replacement — not a repair — and we cover
all shipping in both directions.
Report it within 14 daysEmail service@ws.computer with your order number, a description of what's wrong, and a photo or short video if possible.
RMA + pre-paid return label, same dayYou get a pre-paid carrier label by email. Drop the system at the carrier or schedule a free pickup — whichever you prefer.
We test on arrivalThe unit is logged into our system the moment it arrives, photographed, and tested by an engineer.
Replacement built and shippedIf DOA is confirmed, we build a replacement (same spec, same components) from priority stock and ship it within one business day.
Refund instead?If you'd rather have a full refund than a replacement, just tell us — refunded to the original payment method within 5 business days.
RMA process
Filing a return or warranty claim
Email service@ws.computerInclude your order number and a clear description of the issue. No web forms. We respond within one business day.
Get your RMA numberWe issue an RMA number and detailed instructions. Don't ship anything without it — unmarked packages slow everything down.
Pack the unit in original packagingUse the foam inserts and box your machine arrived in. If you've discarded them, contact us — we can ship replacements at cost.
Ship via the label we sendFor DOA, defects and our errors: we email a pre-paid label. For 14-day buyer's remorse returns: you ship at your own cost using any insured carrier.
We log, test and processOn receipt: photograph, log to your RMA, test on the bench. Refund or replacement processed within 5 business days.
Always insure return shipments
A workstation is worth thousands of euro. Use the carrier we recommend or insure for full
value with whatever carrier you choose. We can't be responsible for damage in transit on
return shipments you arrange yourself.

Lifetime support. Hands-on service when you need it.
Free, unlimited support for the life of your machine — even after the warranty ends. When you need hands-on help, our service starts at €50 / hour.
Lifetime support — included
Free, unlimited support for the life of your machine
Every WS.COMPUTER customer gets unlimited email and phone support, included with every workstation.
Support lasts for the life of the machine. Whether your build is one week or six years old, the same engineers who assembled
it answer your questions.
Email support
Direct line to the build team. We answer every email within one business day.
Phone support
Direct number for active customers. Same-day callback during business hours.
Remote diagnostics
Secure remote session via TeamViewer or AnyDesk — we look at your machine without you shipping it.
Direct line to the builders
You email a person at WS.COMPUTER and get a reply from the team that built your machine.
What "unlimited" actually means
Driver questions, BIOS updates, configuration tweaks, performance tuning advice, software install
help, OS reinstall walkthrough, general usage questions — all free, all unlimited, for the life of the machine.
Advice is always free.
Quick fix
Screen frozen, black or flickering? Restart the graphics driver
Press Win + Ctrl + Shift + B. Windows restarts the graphics driver:
the screen goes black for a second and you hear a short beep. Applications usually stay open.
It works with NVIDIA, AMD and Intel graphics on Windows 10 and Windows 11.
If nothing happens
When the whole system has stopped responding and the mouse pointer does not move, the shortcut has no effect.
Hold the power button for five seconds to switch off, start the machine again and email us — we will go through
the system logs with you. A render running on that graphics card may stop when the driver restarts.
Hands-on service
When you need more than advice
Some things need actual hands on the machine — parts swaps after warranty, complex multi-OS setups,
liquid loop rebuilds, ML/CUDA environment configuration, data migrations. For that we charge by the
hour, with three flat tiers based on complexity. Free quotes, including the
consultation; billed in 15-minute increments after the first hour.

The tier is set before we start and stays fixed. If a task spans
tiers, we bill the lower one. Quotes are free; we'll always tell you what tier and how long before
we start.

The fine print
Service terms in plain English
Quotes for paid work are free and not binding until you confirm in writing (email is fine).
Billing is in 15-minute increments after the first hour. The first hour is always charged in full.
Parts used during out-of-warranty repair are quoted separately at our cost + 10%.
You always own your data. We delete customer data when a job is closed, unless you ask us to keep it.
We back up before destructive operations (reinstalls, BIOS flashes) whenever possible — tell us if you've already done a backup.
Travel time on on-site visits is included in the callout fee for the first 50 km, then €1 / km after.
VAT is charged where applicable; B2B EU customers with a valid VAT-EU number are zero-rated.
Still have a question?
We answer every email within one business day. You talk directly to the team that built your machine.

FAQ
Answers to the questions we hear most. Anything else — talk to an engineer.
Ordering
How do I order a workstation?
Use the online configurator for standard builds, or contact us for a custom quote. Every machine is built to order — nothing ships from a shelf.
Can I order a configuration the configurator does not cover?
Yes. Multi-GPU, custom watercooling loops, custom chassis colours, server platforms — if it is sourceable, it is buildable. Send us your workload and we will quote it.
Do you issue VAT invoices for companies?
Yes. EU businesses receive a VAT invoice with 0% intra-EU rate on a valid VAT ID. Exports outside the EU ship with full customs and export documentation.
How long does a build take?
It depends on the configuration and component availability. You receive a firm build and ship date with your quote. Every system completes a 72-hour burn-in before it leaves the workshop.
Shipping
Do you ship to the USA and Canada?
Yes. Insured DHL Express or FedEx, crated on a pallet with custom foam. We have delivered ~300 workstations to 40+ countries and handle all export paperwork.
How is the workstation packed?
Euro pallet, plywood crate, air-bubble wrap, foam, steel corners and strapping. Internal components are braced for transport. Insurance covers the full value door to door.
What if the machine arrives damaged?
Photograph the crate before opening and report within 7 days. Shipments are insured; we handle the claim and repair or replace — you do not negotiate with the courier.
Warranty & support
What warranty do I get?
Five years parts and labour on the complete system, on top of full individual manufacturer warranties per component. Support by email and phone never expires.
How does a warranty repair work?
Contact us first — most issues are resolved remotely. If hardware fails, we arrange the replacement part or the RMA with the manufacturer and guide the swap, or the machine comes back to the workshop.
Do you support the machine after the warranty ends?
Yes. Lifetime technical support is included with every build — configuration help, upgrade advice, troubleshooting. It never expires.
Platforms
Which platforms do you build on?
AMD Threadripper, Threadripper PRO and EPYC, Intel Core and Xeon Scalable — with single- or multi-GPU NVIDIA RTX and RTX PRO configurations, watercooled or air-cooled.
Air-cooled or watercooled — which should I choose?
Air is simpler and near-silent for single-GPU builds. Custom loops win for multi-GPU density and sustained all-core loads. We recommend based on your workload — see the benchmarks.
Terms and Conditions
The contract between you and WS.COMPUTER. Plain English on top, the legal text below.
1. Who we are and what these terms cover
These Terms govern every order placed with WS.COMPUTER (the “Seller”, “we”) through ws.computer, by email or in writing. Company details, registration and VAT number are on the Imprint page. By placing an order you accept these Terms. We sell to consumers (B2C) and to businesses (B2B); clauses that apply to one group only say so.
2. Products and configuration
Every workstation is assembled to the configuration you choose. The binding specification is the one on your order confirmation and pro forma invoice, not a photograph or a marketing page. Where a component becomes unavailable we offer an equivalent or better part and proceed only with your agreement. Benchmark figures published on this site are reference results for the named workload and are not a guarantee of performance in your project.
3. Prices and VAT
Prices are quoted in EUR net of VAT. VAT is added on the invoice where the law requires it: 23 % for consumers and Polish businesses, reverse charge for EU businesses with a valid VAT number, no VAT on exports outside the EU. Import duties and taxes outside the EU are paid by the buyer. The price confirmed on the pro forma invoice is the price you pay. In case of an obvious pricing error we may cancel the order and refund in full.
4. Order, acceptance and payment
Your order is an offer to buy. The contract is formed when we send the order confirmation. We may decline an order that appears fraudulent, cannot be shipped lawfully to its destination or exceeds our build capacity, and we will say so. Payment is by bank transfer (SEPA or SWIFT) against the pro forma invoice; card payment is available where shown at checkout. For orders above €15 000 we may ask for a 30 % deposit with the balance due before dispatch. Ownership of the goods passes to you on full payment.
5. Build time, dispatch and risk
The “ships by” date on your confirmation is the date we hand the machine to the carrier: our build time plus supplier lead time. Carrier transit is on top and is shown on the Shipping page. Every shipment is insured for its full value. For consumers the risk of loss or damage passes on delivery; for businesses it passes when the carrier collects the goods. Delays caused by carriers, customs, supplier stock-outs or events beyond our control extend the date; you may then wait, change components or cancel for a full refund of what you have paid.
6. Right of withdrawal (consumers)
Consumers in the EU may withdraw from a distance contract within 14 days of delivery without giving a reason. Under Article 16(c) of Directive 2011/83/EU this right does not apply to goods made to the consumer’s specification, which includes every workstation configured in our configurator or by email. It does apply to unconfigured, stock items. The procedure and the model form are on the Right of Withdrawal page. Business customers have no right of withdrawal.
7. Warranty
Every workstation carries a 2-year warranty on the build, parts and labour, counted from delivery. In the first year we cover shipping for warranty service: replacement parts anywhere, and the whole machine within the EU and the UK; afterwards, and for whole machines outside the EU and the UK, shipping both ways is paid by the customer. Hardware is sent to us only after remote diagnosis confirms a fault. The WS.COMPUTER case carries a lifetime warranty on hinges, latches, panels and finish. Each component additionally carries its manufacturer’s warranty, up to 12 years; we handle the claim for you. Powder-coated chassis panels carry a 25-year Axalta coating warranty. The warranty covers defects in materials and workmanship under normal use. It does not cover damage from overclocking beyond stock voltages, physical damage, liquids, power surges, unauthorised hardware modification, software or data. Statutory rights of consumers under Polish and EU law are not limited by this warranty. Full terms are on the Warranty page.
8. Service, returns and RMA
Report a fault to service@ws.computer with your order number. We diagnose remotely first; if hardware must come back we issue an RMA number; in the first year within the EU and the UK we also send a prepaid label. Dead-on-arrival units are replaced or refunded in full. Out-of-warranty service is billed at the rates on the Service page. The process, timelines and any restocking fee are on the Returns page. Always back up your data before sending a machine in; we are not responsible for data on returned drives.
9. Software and licences
Operating systems and software we install are licensed to you by their publishers under their own terms. Windows licence keys are delivered with the machine and are tied to it. We do not sell, sublicense or support third-party software beyond installation and first activation.
10. Intellectual property
The WS.COMPUTER name, logo, chassis design, configurator, benchmark data and all content on this site are our property or used under licence. Buying a workstation gives you no rights to them. You may not copy, scrape or reverse-engineer the configurator or its pricing logic.
11. Liability
Our liability for any claim arising from an order is limited to the price paid for the affected product. We are not liable for indirect or consequential loss such as lost data, lost profit or downtime. Nothing in these Terms limits liability for death or personal injury caused by negligence, for fraud, for gross negligence or wilful misconduct, or any liability that cannot be excluded by law, including consumers’ statutory rights.
12. Data protection
We process personal data as described in the Privacy Policy and use cookies as described in the Cookie Policy. Both form part of these Terms.
13. Force majeure
Neither party is liable for failure to perform caused by events beyond its reasonable control, including natural disaster, war, government action, supplier insolvency, component shortages or epidemic restrictions. We will inform you promptly and offer a reasonable alternative or a refund.
14. Law, disputes and changes
These Terms are governed by Polish law. Disputes with business customers are heard by the court competent for our registered office. Consumers may bring proceedings in their country of residence and may use the EU online dispute resolution platform at ec.europa.eu/odr. We may update these Terms; the version published at the time of your order applies to it. If any clause is found invalid, the rest remains in force.
