Thanks for the reply. I'm now trying to identify which fan is noisy. The
problem is that I already have latest BIOS update installed and week ago
on Ubuntu 12.04 I had no such problem with fans going to fast. My load
avg is 2.0 at max (3 kvms running but not so busy) and long term CPU
utilization is below 5%-10%. The only difference is that previously I
had AMD Catalyst driver installed for Radeon HD 5750 and now I'm using
the default Open Source driver, so I'll be investigating graphics at
first. I also noticed that video card is warmer than other parts of my
set but it might be a false alarm. Thanks anyway for the reply.
