I decided to install an NV5 Silencer Revision 3 on my 7900GT.
Stock Cooler Removed, Core and memory cleaning with isopropyl alcohol.

Temps Idle dropped from 45C to 38C. Load temps dropped from 67C to 50C while running RTHDRIBL for 5 minutes...

Thats with the core at 560mhz and the memory at 1800mhz.

As far as noise goes, I cant hear my computer at all anymore. The silencer is well, silent!

Im about to go test a modified 7900GT bios that has 1.4volts applied to the core and see how I do now I have aftermarket cooling. Ive tried the bios with stock cooling and I got to 600mhz core, but I had tiny artifacts in 3dmark03.

Good job man, but you could have modded the cooler instead of the case ;)

Just make sure that when you use the bios you also try it with a 20mhz delta to test if it is really better than the original one. You can also use 1.3v instead of 1.4v if you want it to run a little cooler ;)

Good luck, and have fun with your card :)

yea I would much rather hack off the cooler instead of the case :D :D with the stock bios did you gain anything after this cooler mod?

basically:

stock heatsink stock volts:

44C idle, 64C Load

stock heatsink 1.4volts:

50C idle, 76C Load

NV Silencer 5 stock volts:

38C idle, 50C Load

NV Silencer 5 1.4 volts:

44C Idle, 57C Load.

at stock volts it didnt help my overclock at all. however at 1.4 volts i was able to overclock the card from my previous max of 570 to 600. (note that the 570 overclock had no delta in the bios and the 600 clock had a 20mhz delta so in effect max overclock increased to 620mhz). My memory overclock didnt change at all, max of 1.8ghz.

Other than being too long, does it fit well? I mean, do all the ram cooling pads align with the ram chips in the card?

One more thing, what would be the best way to shorten the cooler? Using a saw?

why didn't you just chop a inch off of the cooler itself, then chop your case to pieces?

i thought about cutting off some of the coolers exhaust but i dont have anything to do that with. this is a cheap case anyway, only 40 bucks, not really worried about it to be honest.

I've seen a mod just about like that on a case I bought from a VIP member.;) :D

Any idead how the NV5 compares to the Accelero 1?
jVIDIA

Accelero X1 is a litle better in performance and more silent too.

No idea if it fits on a 7900.

accelero x1 is better, but it doesnt exhaust the heat outside the case.

accelero x1 is better, but it doesnt exhaust the heat outside the case.

That's what I thought. I wan't as little hot air in my case is it's almost fanless.

I'm also more concerned about noise and wonder if the NV5 is better in this respect.
