Gaming PC cleaning
& thermal paste.
Dust out of every fan, fresh paste on CPU and GPU. Cool and quiet again. On-site across Helsinki, Espoo, Vantaa and Kerava. Free diagnostics. 90-day warranty.
You don't go anywhere.
Almost every job happens on your own table. Not as a perk — it is simply the arrangement that works better for both of us.
Meet Andrei.
When you book MopsiHuolto, the same person picks up the phone, drives to your door and works on your device. He's a certified laptop repair master with 20+ years of hands-on electronics experience — soldering, console maintenance, high-end laptop servicing.

showing these signs?
If you notice any of these, your PC needs a full cleaning. The longer you wait, the closer you get to a CPU or GPU you can't replace cheaply.
Idle fan speed crept up — case fans and CPU cooler ramp at 50% just to keep up. Filters and heatsink fins are choked with dust.
The card runs hot in modern titles, clocks drop, frame times spike. Fresh paste and pad replacement on the GPU recover most of the original boost clock.
PC powers off mid-game, sometimes with a CPU thermal trip in the BIOS log. Stock cooler is overwhelmed by dust + dried paste.
Front mesh, RGB fan blades, GPU shroud — all grey. PC has been pulling air through carpet and pet hair for years.
Why choose
our service.
Four reasons Helsinki gamers pick MopsiHuolto over a generic IT shop or carrying their full tower across the city.
Our technician arrives at your home or office. No need to disconnect monitors, peripherals or transport a 15 kg tower anywhere.
Fresh paste on CPU and GPU plus full dust removal lets the cooling do its job again. Clocks hold and the fans stop ramping.
We work on AIO loops, hard-tube custom water and air-cooled rigs. ESD-safe bench, no zip-tied cable carnage on reassembly.
All work guaranteed. Free diagnostics before service begins. We only charge if you approve the fix.
How it works.
Four steps. No surprises, no upsell when the case is open and you can't say no.
Call, WhatsApp or Telegram. We arrange a time that works — mornings, evenings, weekends.
Tell us the case, the CPU and the GPU, and what happens under load — clocks dropping, fans ramping, dust you can see through the side panel. You get a fixed price before we set off.
Full dust removal from every fan and filter, CPU cooler off, fresh paste, optional GPU teardown for paste and pads. Cable management restored to original spec.
Reassembled and run under a real gaming load. Clocks have to hold and the fans have to settle before we pack up.
Pick your tier.
Three professional cleaning options. Same premium paste in every tier — you're paying for the depth of work, not the materials.
Side panel off, all fans and filters cleaned, GPU shroud blown out, no paste replacement. Enough for most fan-noise complaints.

Before / After.
What actually changes after a full clean and fresh paste — the difference you notice in a real session. These are outcomes, not sensor readings: we tell you what you will see and hear, not numbers we did not take.
Cooler-test methodology and baseline data come from the TechPowerUp cooler reviews — see their thermal benchmark protocol.

“Andrei responded very quickly and offered me a time on the same day, thoroughly cleaned the laptop and replaced the thermal paste. All for a good price, and now my laptop runs much better!”
“My gaming laptop was bit slow, so decided to call Andrei for cleaning internal parts and replacing thermal paste. The work was done neatly and I am happy with his excellent work. Also, We had some nice discussions during the work. I strongly recommend Andrei for any system related issues.”
“Great service! Good communication during the repair, punctual schedules and excellent results!”
Questions,
answered.

How often should I clean my gaming PC?+
Once a year for normal use, every 6 months if you have pets or smoke indoors. Dust accumulates on heatsink fins exponentially — once the fins are 50% blocked, every additional millimetre makes the cooling work harder for the same result, and the fans have to spin much harder to compensate.
Is repasting the GPU risky?+
Modern GPUs are designed to be serviced — every cooler comes off with 4–8 screws and the manufacturer expects pad replacement after a few years. We use ESD-safe tools, take photos at every step and replace pads with the correct thickness for each board model. €30 of risk insurance compared to a €600+ card replacement if you DIY without experience.
Will this void my warranty?+
On the case, motherboard and power supply — no, opening the side panel is normal user maintenance. On the GPU specifically, removing the cooler voids the manufacturer warranty (typically 2–3 years). For cards out of warranty, our re-paste service is the most cost-effective way to restore performance. We provide our own 90-day warranty on the work.
Do you work on custom water-cooled builds?+
Yes — AIOs, hard-tube and soft-tube custom loops. AIOs we clean and reseat as a standard service. Hard-tube custom loops we drain, refill and rebleed only on request and at workshop drop-off — that's a half-day job, not on-site.
How long does the service take?+
Dust removal only: 45–60 minutes. Cleaning + CPU paste: 1.5 hours. Cleaning + CPU + GPU paste: 2 hours. We work on-site at your desk — no need to box up the tower.
Do you come to my location?+
Yes — most gaming PC cleanings are done at your home or office across Helsinki, Espoo, Vantaa and Kerava. Travel is included in the price. Beyond Kehä III we add €0.50/km and travel for agreed work only. Workshop drop-off is also available.
GPUs and CPUs
don't grow back.
A neglected gaming PC ages 2× faster than a clean one. Once the silicon degrades, no amount of fresh paste brings it back.
Running the CPU or GPU at its thermal limit degrades transistor health over 12–18 months. Boost clocks become unstable, performance drops permanently.
VRAM and VRM pads on the GPU harden and lose contact. RAM modules thermal-throttle, GPU draws more power for the same FPS.
Hot air recirculating in the case bakes the PSU caps. PSU lifespan halves, and a failing PSU can take the motherboard with it.
A €159 cleaning today is the difference between a card that keeps running and one that cooks itself — and a replacement is €600–€1 200.
