While using a laptop computer I noticed high noise levels, caused by the cooling fan.
I decided to check the CPU temperatures using HWMonitor.
The idle temperatures were around 70° C.
And load temperatures were around 85°-94° C.
These temperatures could be high enough to cause thermal throttling, which would affect system performance.
I decided to disassemble the laptop computer and clean the cooling system, using compressed air.
(Be aware that most compressed air cans contain harmful chemicals, so use them outside or in a well ventilated area)
Cleaning the cooling system had a significant effect.
Now idle temperatures were much lower, around 55° C.
And load temperatures were also lower, around 74°-85° C.
Also noticed much lower fan speeds, so the computer wasn’t as noisy as before.
Table of thermal readings:
|Before cleaning||70° C||85°-94°|
|After cleaning||55° C||74°-85° C|
|Improvement||15° C||9°-11° C|

It can be relevant to clean a computers cooling system.
It may improve noise levels, temperatures and performance.
