Have built a PC with the following spec:
Intel Prescott 3G P4 CPU + stock fan
Antec Sonata case
180G SATA Maxtor drive
All seemed fine until I tried to
use it for encoding video - it's primary purpose, when it started to beep randomly. Long
story short and it looks like I have a temperature/cooling problem. I now know that the
Prescott is reknown for running very hot but the problem doesn't relate to the CPU and
case temperature but the PWM temp. The Abit tech I spoke to admitted that their PWM
circuitry can't cope with the on-load power demands of the Prescott. Unfortunately, they
wouldn't let me have that in writing so Scan are unwilling to help out (and I only
discovered this problem after 28 days. Doh!).
So, what's to be done? On the
advice of the the Abit tech, I've reversed the direction of the case exhaust fan so it
blows air across the PWM circuitry but this doesn't really help that much. I installed a
second case fan and this only seems to lower the case temp and not really affect the PWM
temps. The side effect of this is that the machine sounds like something my Dyson would be
proud of is *not* good. He also suggested that I stick small heatsinks to the mosfet power
regulators to increase their ability to shed heat which makes sense but I really shouldn't
have to do this given that Abit state that their board is Northwood compatible..... which
technically it is so long as you don't do anything taxing with the machine
So, any ideas how I can resolve the problem (short of going out and buying a Northwood
Any thoughts much appreciated.
