RPM doesnt mean anything

Im think a much larger area 92mm delta(bout 110CFM i think) would a dam good job on that cooler

I totally agree. Let me give you a tip why people go for the HR-03. We do it because we DON'T want the noise and annoying stock cooler. Why on EARTH should a person want to do this to him self? I just don't get it.

You know, you could actually just fit a 120 mm fan on there with some zipties, it will look muuch better and it will silence your GPU-cooler almost completely.

Sorry, don't want to sound like a partypooper here.

^^ Nice, i didnt know it was possible to have a 120mm fan on there. In that case id go for a sunnon 120. 36 dB (ish) with 98CFM isnt too shabby

Correct me if I'm wrong, but isn't that type of fan a blower?
The air is meant to be channeled through the heatsink and not down into that type of hs like a regular fan.

In conclusion: This is a waste of time
I wonder if the 8800 GTX cooler fits the 7800GT, it kind of looks like it. Will try when I get my HR-03. Clock that GT hard if it works
post #17 of 20
^^ post up some pics if you gett he cooler to mount the 7800GT properly, that should OC nicely

I just moded my 6800, I know it's not the best card, but if someone wants to give me an expensive card for cheap...

I took the little fan out of the heatsink, patched the holes that allowed access of the fan, and placed a 12v fan blowing down into the heatsink. I centered over the original fan hole, taped it into place and voila. It's just as quiet. I was able to lower my temp by 10' Celsius. Now I'm begining to overclock. So far I've gone from 325 core bus to 355 and 594 mem bus to 635. At this setting the temp seems to be the same as it was with the original fan. Does anyone know about how much more I can go and still be safe??? I am running:

Dell XPS 400
Crapy Dell Motherboard socket 775 w/ Pentium D 2.8Ghz
1GB Mem
6800 PCI Express
Vista 32

I Want to get an Asus P5N-E nForce 650i SLI motherboard add my Pentium D processor and add 2 - 2Gb quality mem chips. Then all I'll need is a nice 8800 card. Well, for now I'm having fun and dreaming.

You are 100% correct. This type of fan sucks air in the top and blows out the sides. With his mounting direction it has minimal effect. Inverting the fan would suck air across the fins and exhaust the heat to the sides, somewhat of a better idea. But the squirrel cage won't turn that way.

I would like to see the pinouts of the cards fan header and see if an aftermarket fan could be hooked to the card directly for the software to control the speed as if it was stock, so Rivatuner or ATITools etc. could adjust the fan speed with improved performance.

I am using HD3870s at the moment with a 4 pin header. Possibly with a PWM fan??
