Making P5WDH ready for Conroe: An Illustrative Guide

[davefr]

If anyone is interested I did a thermal IR scan on a P5W DH on the bench doing a torture test. It has a 930 CPU OC'd to 3.75 Ghz at 1.35 Vcore. Ambient is 20 degrees C. It's using the stock Intel HSF with Q-fan off (ie max RPM). There is no other active airflow since the board's on the bench.

Here some of the hot spots:

Marvel ethernet chip - 48
Southbridge - 47 (center of heatsink)
Northbridge - 40 (center of heatsink)
Mosfets - 40
Heatpipe/heatsink area closest to I/O's - 35
Silicon Image controller - 40

Everything else is <35 degrees.

CPU measures 47 degrees from Asus Probe.

I'll probably use the OP's recommendation for the SB but leave the NB alone. That Marvell chip get's a lillte toasty but I'm not sure is it's an issue once the MB is in a case with decent airflow. I also think it's wise to remove those silly decorative ASUS covers. (especially on the SB)

UPDATE:
I removed the SB HS, cleaned it up, applied AS5 and repeated the test. The SB now measures 46.5. It looks like about 1.5 degrees reduction come from this method.
