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?
[root@harpo ~]# more /etc/sysconfig/lm_sensors # Generated by sensors-detect on Tue Jul 11 11:49:07 2017 # This file is sourced by /etc/init.d/lm_sensors and defines the modules to # be loaded/unloaded. # # The format of this file is a shell script that simply defines variables: # HWMON_MODULES for hardware monitoring driver modules, and optionally # BUS_MODULES for any required bus driver module (for example for I2C or SPI).
HWMON_MODULES="w83627hf"
# For compatibility reasons, modules are also listed individually as variables # MODULE_0, MODULE_1, MODULE_2, etc. # You should use BUS_MODULES and HWMON_MODULES instead if possible.
MODULE_0=w83627hf [root@harpo ~]#

I used to have a HP 320 generation 2 server that I used as a desktop. it had a bunch of tiny fans that screamed like a banshee.
it turns out that one of the RPMs they shipped with it (on CD, not actually installed) contained a driver that toned down the fans to a soft roar. I'm sorry to say I have no memory of what the driver was.
but if this system is from a vendor that supports Linux, they might have some suitable driver.
good luck!

That's in the firmware. You may, or may not, be able to do something with ipmitool, but I don't think so. Reboot, and look in system setup. It may be under performance settings.

Warning:I'm new to CentOS and have not tested the suggestion below (with Linux). So please research if it sounds like a good idea.
It may be worth trying to bypass the issue by installing VMware ESXi and setting up CentOS as a virtual machine.
This will give you additional control and backup options for the system.

or maybe try fancontrol from lm_sensors package?
