min/current/max for CPU fan looks strange 940/2474/2100 (middle number fluctuate a little)

that max value is obviously wrong, and I think i need more rpm when doing a lot of calculations.

I have done that : https://support.apple.com/fr-fr/HT201295

changed nothing.

switching to auto, or doing anything else lead computer to crash badly (grey screen chinese text etc) in a random fashion.

what temperature do you suggest max for cpu ? i see 90°C now.

I wonder how you managed to set RPM to 2477 if the max is 2100
