Default Cooling my 6800GT

Well,

when I first go this thing and installed it, it was idling at like.... whoa, 60-65C. Geesh!

I noticed the fan on the 6800 GT sucks air through the card and blows it out. I got to thinking that all that hot air blowing out and bouncing off my pci card was eventually being pushed back towards my intake thus blocking that air flow.

Simple and fun solution. Move PCI cards down so there is two empty slots below my 6800GT. Took precise measurements of space between closest pci PCB and the 6800. Then made a box that had an opening that was a little wider than the circle of the 6800 fan so all hot air would blow into the box. Then, the side of the box closest to the plates covering the pci slots should be removed and the plates should be removed as well. So if you can imagine, you have this box that fits snugly inbetween 6800 and pci cards that utilizes the 6800 fan to blow all the hot air out of the opened pci banks.

This allows more cool air to reach my north bridge, my cpu, and my 6800gt.

My 6800 GT now idles at 54c, my northbridge droped about 10c, and my cpu dropped about 2-3c.

Plus, you can paint it or make it out of other more creative materials. But most importantly, it works!

i do a similar thing for my cpu...there're perforations in the side of my case so i made a duct/sleeve so it draws cold air directly from outside the case. drops about 5'C. i made it out of translucent orange plastic

i also took a jigsaw to the top of the case and added an extra fan, that dropped the cpu another 1-2'C and the ambient case temp 2-3'C.

You could have easily jsut bought a vantec dual fan pci card and placed it under the 6800 GT and it would have done the same thing. Plus it looks cool as both of the fans are UV blue with LEDs

I slapped this 120mm fan right in the side of my case that has a speed control knob mounted in a PCI "L" bracket sticking out the back. The 120mm fan blows right on the CPU and just above the back/top of the video card. If I crank that baby up, my case can almost float around the room like a hover craft from all the air coming out of it.
