I have just installed CentOS 6 i386 onto an old rack server (it's gonna be a Bacula storeage server and is a 1U 1/2 depth chassis)
I did a minimum netinstall and so far so good. However, I have one problem. The CPU fan is going at full speed constantly. Not a real problem apart from (a) it will affect the fan's lifespan and (b) it's noisy.
I've done some Googling and found some help. I've installed lm_sensors and run
sensors-detect.
After reboot I get the following:
[root@harpo ~]# sensors acpitz-virtual-0 Adapter: Virtual device temp1: +40.0°C (crit = +75.0°C)
[root@harpo ~]#
which implies that it can read the CPU temp, but the fan is still going at full speed. Can anyone suggest what I need to do next to enable fan speed control?
