I don' think that the fans need to run at 3000RPM, though having done lots of reading I haven't found anywhere to adjust them with.

The chassis is basically a 4U industrial SuperMicro chassis with very large PWM fans (80mm I think?). Hw.product=X9SRE/X9SRE-3F/X9SRi/X9SRi-3FThe CPU is a Xeon E5, which per the above is downclocked to 1200RPM.īasically this seems strange, though I know the kernel/BIOS should adjust the fans speeds automatically but for such large fans they are making quite a bit of noise while another machine running FreeBSD also in a SuperMicro chassis is almost dead silent.
