ok to disengage fan control on W520 temporarily?
Posted: Sun Aug 14, 2016 1:45 am
There are a few things that I use my W520 for that make the CPU kindof warm - eg, kernel builds, bitbake, etc...
The fan control seems to stop well short of the fan speed when the control is disengaged and I have noticed that by disengaging the fan control temporarily while doing these things that cause all cores to go to 100%, it lowers the temperatures significantly (for the most part, they stay below 80C). I couldn't care less about the noise.
My question is this: what is the risk of harming the fan motor if the speed control is disengaged temporarily (usually less than 1/2 hour)?
Also, what is the best way to control the fan and what usable speed range should I be able to get under control (right now, disengaged is usually a little less than 5000 rpm, highest under control is around 3800, which puzzles me a bit).
