High PSU fan speed
Hi evereyone
I am struggeling with very noisy PSU fan speeds. I've had this issue a while back and a firmware upgrade of the 2 power supplies fixed the issue back then. However, there is no FW upgrade available now and there is nothing I can think of to fix the issue.
The machine is a Dell T630 with 2 Delta 1100W PSUs (PN: Y26KX). FW is 00.1D.80. Usually the power draw peak is sub 200W according to iDrac.However, there are occasianly peaks of ca. 300W.
Sometimes a reboot and unplugging the PSU's helps but the issue comes back again. No errors in iDrac reported. System fans are normal.
Power settings:
Power Cap Policy: disabled
Redundancy Policy: Input Power Redundant
Hot Spare: enabled
Primary Power Supply Unit: PSU1
PFC: disabled
Is there a way to find out why the PSU fans ramp up that much? Are there any IPMI commands to check PSU fan data?

Hello,
This could be happening because of poor airflow in the case or a buildup of dust. Also, a faulty part in the PSU or somewhere else in the system might be causing it to draw more power, which makes the fans speed up. Do you see any warning or error on system event logs? Please ensure your iDRAC and BIOS are also up to date.
from here you can review commands iDRAC 8/7 v2.50.50.50 RACADM CLI Guide (https://dell.to/3MrRdoj)
Hope that helps!
