My custom 8800GT cooling solution

[yacoub]

I also received my sinks yesterday. Unfortunately I only managed to take apart my 8800 GTS G92 before passing out last night from exhaustion. Haha. When I woke up this morning I installed the sinks along with a Zalman VF900 I had from an old 6800 GT.

I didn't have much time to test the setup this morning but from what little time I did have to test I went from:

IDE: 48C->40C
LOAD (ATITOOL error test): 81C->66C

The tests were ran with both the card and fan at stock speeds. I used MX-2 with the sinks and cooler. The ATITOOL error test was run for 10 minutes. Previously with air I was running the card at 815/2000/1915 @ 50% fan speed. I'll get to testing my old numbers tonight with the new setup.

Nice work Ian! I'll post some pictures tonight.

That's really exciting to hear as I have a VF900cu and some MX-2 sitting here on my desk waiting for the heatsinks to arrive (hopefully soon).

edit: I see your later post now about some temperature issues, but that sounds like it's with your mounting of the vf900 and seems relegated to that one program you're testing with. either way, I don't plan to run anything super-intensive so i think it'll be fine for the gaming i occasionally do but hopefully quieter than the stock heatsink/fan which is my goal. =)

You're getting a set of the rev. 2 sinks. As soon as I found out that I had the production run locked in for sure last weekend I figured it would be unfair to send the old model to any existing orders.

I PM'ed you to see what color you would like.

Looking back I don't think it was a mounting issue. After the installation of the VF900 the temps did drop in various areas (idle, ATITOOL, games, etc.) and when I broke it down to re-seat the heatsink there was no real evidence of poor contact. I've come to the conclusion that the VF900 just doesn't handle heavy temp load (e.g., oZone3D fur test) extremely well.

At full blast the VF900 is actually quite louder then the stock 8800 GTS G92 which runs the fan at 36%. I would say at max speed the VF900's fan is about as loud as the stock fan at 55%. If you're not running anything crazy though, as you mention above, you can always dial down the VF900 fan. Shoot me a PM when you get it all up and running. I'm curious what sort of results you achieve.
