One fan running extremely slow

Neodone · ‎12-05-2020

hi,

As shown in the screenshot, one of the laptop fans is stuck at 100-200 rpm while the other fans is running at high speeds and the CPU temp is also relatively high. Not sure if this is a hardware issue or a software one.

@Neodone

Fans are controlled by heat sensors. Depending on the heat on its area, sensor will "tell" how fast the fan can run. From my view, this is a good design.

Hope this makes sense.

Thanks @Banhien.

However, in my case, both the fans are on the same heat sink. Not sure if we would have two different sensors with one always making the fan run at 100 rpm.
