Q: my laptop's fan is loud, how to make it stop? I have cleaned my laptop many times, and there is no dust inside.  The temperatures the speedfan gives me are:


*

*HD0: 31 C

*TEMP1: 39 C

*CORE 0: 24 C 

*CORE 1: 25 C


When the 'TEMP1' goes over 40 C it starts spinning fast and when it goes under 40 it stops spinning fast
The problem is that the temperature is always changing (from below 40 to over 40), so every few minutes the fan starts to spin loud and then stops working.  This then repeats.
What can I do about it?

A: This really varies from system to system, speedfan can probably help you if you fiddle about in the settings enough.
This is how I got my computer to behave, perhaps you can use it as a starting point for your own experimentation. (Yellow highlight where I have made changes)
