Built the new computer with the following hardware:
Intel P4 650
ASUS P5LD2 Deluxe motherboard
DDR2 PC2-5400 Gold Dual Channel modules from OCZ
Artic Cooling Pro 7 HSF
COOLER MASTER Centurion C5 CAC-T05-US Pearl White Computer Case
The motherboard came with asus’s probe II software which monitors cpu/mobo temps, voltages, fan speeds etc. Because I could monitor all these things, I decided to give overclocking a shot.
At the stock frequency (3.4Ghz), the P4 650 runs ~34C during idel and ~45C during load. @ 4 Ghz the temps have only increased by 5C. The hottest the chip has been in the last week was 51C under load when I was using the oven in my small apartment. I didn’t touch the Vcore setting, mobo temps are never higher than 35C, and the computer is totally stable.
I was a little amazed at the performance especially b/c the review which got me interested in the setup ran their test without a case. I figured b/c my setup would be concealed in a case AND the mobo would be mounted vertically in the case (heat rises right?) that I would get much higher temperatures than the review. For this reason I got the case which I though would provide the most air circulation. It’s got a 80mm fan in the front pulling air in and a 120mm fan right behind the HSF pulling air out. The front of the case is made of aluminum mesh. The PSU also has 2 fans pulling air out of the case. I guess b/c of the great air flow, my temps are lower than the reviews.
Just wanted to say thanks to everyone for their inputs which helped me build this monster of a video encoding maching.
