Laptop overheating in a Batumi summer: heat, humidity and dust
In a Batumi summer one complaint comes up again and again: the laptop is roaring, burning your lap and slowing down. The cooling cannot keep up — but the cause is not always the hardware. Here is why it happens here in particular and what to do.
Why summer makes it worse
A laptop is cooled by room air. When your flat is 30 °C, the fan has to push much more air to keep the processor safe. Humid sea air plus dust turns the radiator grille into felt faster.
When the processor reaches its limit, it lowers its own speed so it does not burn out. That is the "slow in summer" effect: the computer is not broken, it is protecting itself.
- The fan is loud all the time, even on simple tasks.
- The case above the keyboard or underneath is hot to the touch.
- Video and games start stuttering after 10–20 minutes.
- The laptop suddenly switches off under load.
What you can do in 10 minutes
- Work on a hard desk, not on a sofa or bed: fabric blocks the vents underneath.
- Lift the back of the laptop by 2–3 cm so air flows freely.
- Close extra tabs and startup programs: less load means less heat.
- In Windows use the "Balanced" power mode instead of "Best performance".
- Do not leave the laptop in the sun by a window or in a car.
Software comes first
Often a laptop runs hot not because of the hardware but because Windows is constantly busy in the background: too many startup programs, stuck updates, wrong graphics drivers, a crypto-mining virus. That is what I check first — and often it is enough, with no need to open the laptop. This is exactly the kind of work I do on a home visit.
On thermal paste I have my own rule: I do not touch it without a reason and do not take on "just replace the thermal paste" requests.
- Task Manager shows the processor at 50–100 % even when you are doing nothing.
- The laptop started running hot after installing a program or game.
- The fan is loud right after switching on.
When it needs cleaning
If the software is fine but the laptop still overheats and shuts down, there is most likely a lot of dust inside. Then I clean the dust out of the cooling system. I replace the thermal paste in one case only: if I open the laptop and see that it has dried out or cracked. If the fan itself is faulty or the board needs soldering, that is a job for a shop with equipment — I will say so directly and suggest where to go.
- The laptop switches itself off — do not wait, overheating shortens the life of the board.
- You can see dust in the side grille, or the fan rattles or does not spin.
- The laptop is more than two or three years old and has never been cleaned.
What not to do
- Do not vacuum the laptop or take it apart "from a video" without experience: it is easy to tear a ribbon cable or break the clips.
- Do not put it in the fridge or right against the air conditioner — condensation is more dangerous than heat.
- Do not tape over the vents to "keep dust out".
