Asus P4C800 Deluxe only has a heatsink on it without the fan. When overclocked it gets pretty hot. So that's why i am looking for a cooling solution for the chipset.
I went to a local computer/surplus electonics shop and got a coolermaster h/s fan combo that was a bit bigger than my chipset h/s peeled off the old one and stuck the new one on and it only cost me $3.00 it might not work for extreme oc'ing but it works great for my {notorious for chipset overheating} ecs k7s5a pro board so you might look around in a few shops to see what you can find
the only issue i had was it was a tad bit bigger than the stock one and with the bad placing of some capacitors it would almost touch them so I decided to cut it down a bit...wow that was a pain...
