I have a problem with a fan connected directly in mainboard supermicro A1SAi-2750F.
First test i use the generic case fan 4pin (no data spech) the fan speed oscillation up and down
and mainboard give alert.
i buy another fan NF F12 PWM same problem...
I fix temporary with a custom build cable 4 to 3 pin connector cable, but the speed are fixed and more noise.
i read that i use ipmi to setting some parameter but is safe? this parameter change speed fan?
are mainboard specific value?
tnks.
