I once replaced the fan of an orb-style HSF (I'd rather forget it). Initially I took a smaller fan that fitted inside the (slightly bent) fins. But later I cut out the frame of a larger fan and glued it at the bottom of the HS. Cooling performance was marginally reduced, but the noise level went dow...

Zhentar, don't know if it really helps but a friend of mine returned his MOBO to QDI for a modification (he got wrong temperature readings from the CPU-diode). Once he got it back, it wouldn't POST at 133MHz, only at 100MHz. I tested both CPU (Palomino) and RAM in my system, and they all worked well...

I find the buzzing more annoying than the slightly higher
PSU fan speed at idle.

CPUidle puts a tremendous stress to power regulators, changing
the load 50-70% in just a few clock cycles, thus causing harmonics.

Nay, I think you'd better replace the case fan. It shouldn't be that hard to make your PSU the loudest component. Running the CPU without a fan usually requires a bit more attention to airflow and in some cases other components. (even if it is a low power CPU by today's standards) You could also rep...

I was disappointed with the ZM-300A. If you’re on a budget, go
for the FSP300-60PN (even the PF version is quieter than the
Zalman, and much cheaper).

Or even better: a PSU ranked higher on the recommended list

IMO, cooling parts that don't need extra cooling (like the VRM) is usually a waste of time (and noise). If your Vcore is stable then everything is ok! Unlike your CPU, MOSFET’s are designed to operate at high temperatures. Maximum junction temp: 120-150'C! It's just a piece of silicon and plastic an...

1. Undervolt (0.05-0.15V gives you a ~5-10'C temp drop at full load ) 2. Turn the fan to suck air from the HS. (loose ~3'C in some systems) 3. Remember, 57'C isn't that bad if you are pleased with the noise level. Spec says 85'C. Real world apps will always load your CPU less. The Volcano 7+ is clea...

Or, you could just solder the wire to the pin terminal.
It will be a bit more fragile, but I doubt you would notice

I think mdhare meant internal PSU temps. How did you measure the CPU temp?

Or buy a new one if your MB support reading from external t...

My barracuda V (ATA) 120G(8M) is installed in a 3.5" bay with rubber
grommets. Idle temp is 34'C (MB:27'C). The case is cooled by one
120mm fan in the bottom of the case (the case hangs under the desk)
and one in the rear, both running at 700rpm (~5.5v).

Maybe you should consider a front intake fan?
