Tips for restoring a sluggish laptop often linked to cooling problems.
The laptop has been getting much slower over the past couple of years. Many 3D games are now hard to play, and it feels sluggish overall. The fans keep running loudly even when CPU usage is low, and temperatures often exceed 85°C, sometimes reaching 90°C or more. This suggests cooling problems are the main issue. You mentioned checking the thermal paste and possibly cleaning the fans. It might help to open the case and inspect those components.
Search for instructions on taking apart the laptop completely, including fans, heat pipes, and fins. Gather a soft brush, thermal paste, and compressed air. Organize screws using a method that keeps track of their placement and connectors. Avoid forcing anything open if you're unsure. Expect a lot of dust in the fans—remove it thoroughly. During reassembly, apply thermal paste exactly as before, with correct spots and amounts. Ensure heat sinks and pipes are secured with proper pressure; incorrect handling can worsen the situation.
I followed this tutorial and succeeded! The heatsink was covered in dust. Now it stays between 40-50°C during idle, the fans run much quieter, and in games it only hits around 80°C. My frame rates have doubled or even tripled! This was my first DIY electronics project, which is awesome that it worked. Unfortunately, while fixing my laptop, the charger cable broke, so I now have to handle it carefully for charging. I’ve already ordered a replacement.
