I'm building a HTPC with a Pentium 4 3.2ghz Northwood CPU, two 512meg
sticks of Mushkin PC3200 ram, Zalman CNPS 7000-A AlCu heatsink, Arctic
Silver Ceramique thermal compound, Intel 865 PERL motherboard. and a ATI
Radeon 9800 Pro video card. I'm using a 400w Seasonic Super Silencer
power supply and a Silverstone LC-10 case.
I've finally got the motherboard to post (see my other message titled
Motherboard will not POST). But now I've having a problem with the CPU
temp. At the BIOS screen the CPU temp is 43 deg C after 1 hour of
running. This is is with the motherboard lying on the table in the open
air. If I put it in the LC-10 case even with all the fans hooked up the
CPU temp rises to 50 deg C according to the BIOS and I dont have the
hard drive, video capture card or DVD drive power cables connected. Yet
the heatsink is barely warm when I touch it.
I"ve taken off the heatsink, cleaned it and the CPU with Goof-Off (as
recommended by Arctic Silver) and 91% alcohol and reapplied thermal
compound 3 or 4 times and end up with the same temps. I even tried a
Seasonic Super Turnado with the 120mm fan and the temps inside the case
stayed the same. I'm going to be adding a lot of heat producing
components (more hds, more video capture cards) so I need to figure out
why the CPU temp is so high. I dont want to add more or higher powered
fans it I can help it because of the added noise.
