Hi
I have updated the bios to the version A08 which is the latest for this system. After restart the fans still run full speed and are very loud like before.
Disconnected and reconnected all the fans like you suggested but the problem is still there.
The fans seem to start running at full speed straight away after I turn on the system.
It looks to me it is some kind of hardware fault since none of this helped.
Any other suggestions or at least identify the faulty part to replace.
Thanks for you help.
