Hi Guys,
i manage to solve the fan speed issues(sorry it took me a while to post) and now fan speed down to 300rpm constant and dead quite :)
for those ones who have the same issue i would like to share the process solution without a script.
1. First issue was to update the ipmi values in the shell using the ipmitool
The issue was the * " symbols that was on the FAN1 and values needed to be excluded from the code.
the correct code format is:
~]# ipmitool sensor thresh FAN1 lower 100 200 300
~]# ipmitool sensor thresh FAN1 upper 1600 1700 1800
~]# ipmitool sensor thresh FAN2 lower 100 200 300
~]# ipmitool sensor thresh FAN2 upper 1600 1700 1800
Note - values are for my fan specification, you should check the values for your fan manufacture specification.
2. after updating the ipmi values by using the ipmitool, you can confirm using the following code
~]# ipmitool sensor list all
here is how mine looks after the ipmi update with my fan specification
3. After updating the ipmi values my fans was running at 1600rpm constant full speed and was unable to drop the speed
to the normal ultra quiet speed as specified by the fan manufacture.
I have discovered that rebooting the IPMI itself is necessary after using ipmitool. Do this by selecting the
Maintenance -> Unit Reset menu item under the IPMI web interface. After this, my RPMs went way down to reasonable levels.
here is the end result:)
hope that helps
