Fan

modify fan speed in proliant

After inserting a Tesla P100 GPU, which has no fan, I monitored the temperature using “nvtop”. I noticed I went above 78 degrees celcius, causing it to throttle.

There is a method to change the ventilator speed in the BIOS. Switching it to performance is not a pleasent experience, as all fans turn at 100%.

Patch ILO

turn out there is a patched ILO rom. There is a procedure where you have to set switch 1 of the maintenance switch on the systemboard. (next to powersupply)

switch 1 of maintenance switch back to 0

reset ILO

I had a problem while executing : fan info (nothing showed) reset /map1 (this resets the ILO)

set fan speed

Temp seems OK if fans are at 55%
