[Herts] Irritating Alarm

[Kevin Sheehan]

Does your motherboard have speed throttling for the fans?

As I have had propblems with these a few times. I was thinking could it 
be that the motherboard is picking the temperature increase up (Not 
neccessarily overheat), trying to throttle up the fans but one of them 
is damaged or a low noise one that has a lower max RPM and this is 
setting the alarm off? I.E. at idle the RPM is above the alarm 
threshold, but throttled up it cannot reach the alarm threshold.

Anyhow just  a thought.
