Supermicro 1u server: mainboard ver. X9SCI/X9SCA
The fans appear to be spinning at max speed and it's very loud.
I want to decrease the fan speeds using pwmconfig and fancontrol but the fans continue to run at max speed even though the temps are between 25 - 31 celsius.
The temps are nowhere near the maximum set in /etc/fancontrol (60 C) so I can't figure out why most of the fans continue to run at 11,000+ rpm's.
I configured pwmconfig:
Code:
[root@host]# cat /etc/fancontrol
# Configuration file generated by pwmconfig, changes will be lost
INTERVAL=10

And lm_sensors appear to be reporting properly --

Looking for guidance on what to configure or what to change in order to slow the fans by a few thousand rpm's. Based on my temps, the high speeds don't seem necessary.
Sidenote --- I have two other Supermicro 1U servers in the same rack (1 CentOS 7 and 1 MS Server 2012), at virtually same temps. (mainboard ver. X10), and those fans are smooth and quiet at 4500 - 4900 rpm's.
Thank you for your help.
