My P4S533 board will not source enough current to drive an Intel hsf full
speed. Another fan that required even less power than the Intel produced
the same result.
Perhaps your board has a similar problem. In that case it would be quiet
with Q-fan regardless of how hot the cpu gets. And if your hsf is the
factory-furnished Intel, it's temperature controller could be defective or
overidden.
I run the Intel hsf off the main harness and it is always quiet. The only
time I hear it is when I slow the case fans and the Intel fan speeds up due
to the temperature increase.
