Re: PE1950 fan speed

[michalwd1979]

Hi Vernon,
I am not 100% sure but I think that fan speed is set by BMC and you can not do anything about it. Simple test if fan speed control is working is to pull out one fan when server is running. For me (PE2850 running gentoo) this speeds-up other fans. When I putted it  back fans gradually slow down to normal speed. Can you check temperature of the CPUs using lm_sensors or openmanage or anything? In 2850 dell sets CPU warning temp to 120 deg, and maybe it assumes that running hot is normal for the system. 
Anyway when I made a crash-test (a few compilations and a few cat /dev/urandom >/dev/null) some time ago I got about 62deg max on CPUs but I think this is because of completely changed cooling system.

Regards,
Michael
