Southbridge cooling mod

post #1 of 12
Thread Starter 
For anyone with a P5W DH, you might have noticed that your mobo's chipset runs around 50 Celsius in a 20 degree environment under load. I didn't like the thought of that so I found a small fan and installed on top of the south bridge.

It actually got my mobo's temp down to 40 under load... I have to do more experiments though.. what can i do to stress the chipset?

Both the NB and SB have a metal peel off thingy over them with the ASUS logo on em, it is held on with some glue. TAke that off to expose all of the fins of the heatsink, that will help temps.

Up the chipset votlage to the max to see what gives, if the BIOS has the option.

How are SB and NB temps monitored in this board? Can't be "motherboard temp" because it rarely hit 45c under load and the NB feels hotter than 45c, and very hot when the side fan is used as exaust and not intake, intake cools it off alot.

Not really, more like peeling off a sticker.

Or you could remove the whole thing and put this on: http://www.pccasegear.com/prod4941.htm

That will do a better job, and won't get in the way of your gfx card.

But don't remove the thermal pads under the IHS, I made this mistake and wen I remounted it crushed the resistors.
