When the computer gets hot enough to warm your hands, the fans sound like an aeroplane and the game suddenly shuts down — it is time to act. Overheating is one of the most common problems we see with both gaming rigs and everyday laptops in Lerum and the surrounding area.

Datorhjälp Lerum cleans heat sinks, replaces dried-out thermal paste and measures temperatures under real load — not just on the desk. We work with desktop PCs and laptops, and explain what caused the problem so you can avoid it going forward.

Cooling service and cleaning starts at 599 SEK. You get a clear assessment before we open the chassis, and most cases are completed the same day if you drop off at our office on Göteborgsvägen or book a home visit.

Cleaning an overheating gaming PC in Lerum — technician replacing thermal paste and cleaning cooling
Cleaning and cooling service for CPU and GPU — gaming PC and laptop in Lerum.

Why overheating is not just annoying — it is dangerous

A computer running hot performs worse. The processor and graphics card automatically lower their speed — so-called throttling — to protect themselves. You notice it as sudden FPS drops in games, stuttering video and programs that used to feel fast suddenly feeling sluggish.

Over time, heat can cause permanent damage. Solder joints can crack, thermal interfaces dry out and fan bearings wear out. Many customers contact us only when the computer already shuts down mid-work or mid-game — by then the problem has often been going on for months.

Common causes include dust in heat sinks, dried-out thermal paste, blocked air intakes and incorrect fan curves in the BIOS. On laptops, heat pipes and fans are often hard to reach without the right tools and experience.

Professional cleaning and cooling optimisation

We start with temperature measurements at idle and under load so we know exactly how bad it is. Then we open the computer the right way — without unnecessarily damaging warranty seals — and clean heat sinks, fans and air channels with suitable products.

Thermal paste on the CPU and GPU is replaced when it is dry or hardened. We check that fans spin freely, that cables do not block airflow and that fan curves in the BIOS or software are reasonable. On gaming PCs we can also adjust fan profiles for a better balance between noise and temperature.

After the work we run stress tests and compare temperatures before and after. You get a simple report and concrete advice on airflow, computer placement and how often cleaning is needed — especially if you have pets or smoke indoors.

What you can expect

After completed cooling service, temperatures usually drop noticeably — often 10–25 degrees depending on how clogged the computer was. Fans should become quieter in everyday use and the computer should no longer shut down under normal load.

We give you honest feedback if the hardware is still in the risk zone. Sometimes cleaning is not enough — then a new fan, better cooler or adjustment of the chassis airflow may be needed, and we quote that before ordering parts.

Cleaning is maintenance, not a permanent fix if the computer sits in a dusty environment. We recommend intervals based on your situation and are happy to show you how to monitor temperatures yourself with free tools.

Why choose Datorhjälp Lerum for cooling service?

We have worked with gaming PCs and laptops for over 20 years and know the difference between a quick vacuum and a proper cooling service.

Before and after measurements

We document temperatures under load — not just guess. You see in black and white that the work helped.

Experience with gaming and laptops

Desktop rigs with liquid cooling and ultra-thin laptops require different methods. We have tools and routines for both.

Clear pricing from 599 SEK

Basic service with cleaning and paste replacement has a fixed starting price. Extra parts or extensive repairs are quoted separately.

Workshop in Lerum and home visits

Drop off on Göteborgsvägen or book a home visit in Floda, Gråbo, Partille and Gothenburg — you choose what suits you.

No unnecessary upgrades

We only recommend new parts when they are actually needed. The goal is a cooler and quieter computer — not an expensive invoice.

Varaa aika

Good to do before you book

  • Save and close all open documents and games
  • Note when the problem started and whether it happens with specific programs
  • If possible: install HWMonitor or similar and note maximum temperatures
  • Place the computer on a hard, flat surface — not on a bed or sofa
  • Bring the charger if it is a laptop
  • Tell us if the computer was recently moved, cleaned by yourself or if you changed the paste

How to reduce the risk of overheating

  • Clean air intakes carefully with compressed air every six to twelve months
  • Position the computer so all sides have free airflow
  • Replace thermal paste every three to five years — more often with heavy gaming
  • Keep BIOS and chipset drivers up to date
  • Use fan curves that balance noise and temperature — not silence at the expense of cooling
  • Consider dust filters if the computer sits on the floor or in a hairy environment

Usein kysytyt kysymykset

How much does it cost to fix an overheating computer?
Basic cooling service with cleaning and paste replacement starts at 599 SEK. If fans or coolers need replacing you get a quote before we order parts.
Does 599 SEK apply to both laptop and desktop?
Yes, the starting price applies to basic service for both. Some laptops with hard-to-reach cooling systems may require more time — we inform you before expanding the work.
Can overheating permanently destroy my computer?
Yes. Prolonged high heat can damage the CPU, GPU and motherboard. The sooner you act the better — do not wait until the computer shuts down daily.
How often should I clean the inside?
In a normal home environment every 12–18 months. If you have pets, smoke or the computer sits on the floor we recommend every 6–12 months.
Do you help gaming PCs with liquid cooling?
Yes. We check hoses, pumps and radiators, clean and ensure the coolant circulates as it should. Leaks are always investigated thoroughly.
Will I notice a difference right after service?
Most people notice lower temperatures, quieter fans and more stable performance immediately. With very clogged systems the improvement can be dramatic.
Can you come to my home?
Yes, we offer home visits in Lerum, Floda, Gråbo, Partille, Gothenburg and Alingsås. Book via /boka or call us.
Is opening the computer covered by warranty?
Opening the chassis can affect the manufacturer warranty on some brands. We inform you of the risk and handle the computer carefully — many customers prioritise saving the hardware over a warranty that is about to expire anyway.
