Good to know. Can you easily remove the stock cooler and replace it with somethgin quiet like HR-03?

That's odd... Is the noise whooshing or is it bearing or motor noise? Is it noisier now than it was when new?

Because if i unplug all my hardrives and stop the case and CPU fans i still think its very quiet at 25%, in that situation the NeoHE is the noisiest part even though its not ramping up. have you tried slowing the fan down?

Cant feel any air coming from the cooler but will test it later when ive done more game testing when the gpu is burnt in

this was because I hadnt taken the backplate off from the case

should see some better temps now

I'd had enough of the stock GF7900GTX cooler so replaced it with a Thermalright HR-03 passive cooler instead.

The main issue I had with the Nvidia cooler wasn't that it's particularly noisy in itself. It just seemed to add to the overall noise from the PC.

The PC now only has the single exhaust fan running as before.

Standard Antec PSU's aren't particularly quiet. Replacing it with something such as a Nesteq Semi-Passive PSU in ASM mode makes a big difference.

The NeoHE is as quiet as the Seasonic S12 at low loads, so it is pretty damn quiet.. Other Antec PSUs are a different matter.

Update on my 7900GTO: I've tested out Nibitor and it seems it can't do overvolting due to hardware limitations....BUT IT CAN do undervolting! I haven't tried under 1.3v as that requires voltage table setting. The standard settings are 1.3V for 2d and 1.4V for 3d. So I've set everything to 1.3v now. Hope more people get a chance to take advantage of Bios editing for undervolting, it's an awesome free and easy soft video card mod for us quiet addicts.

I find it rather funny because now the card isn't stable at stock clock speed. Normal speeds are 650 core/660 memory. I now have it at 623 core/725 memory and this seems fully stable. At full burn, based on an estimate off my UPS monitor, I'm using around 140-150 watts for my full system. My highest gpu temp so far is 63C. And it's amazingly quiet, I love the stock cooler

I'd definitely recommend this card to anyone who wants a low power beast of a gpu at a great price. If you don't mind dropping the clocks a bit, it's an extremely easy thing to undervolt to 1.3V...and possibly even lower...although at that point a 7900GT might make more sense as it's basically an undervolted 7900GTX/GTO at 1.2V.

140-150W for the full system is pretty nice.. Mine is up to 230W AC at load.. about 30W more than the 3500+ and x800GTO.

I guess it probably helps to have my processor undervolted, gpu undervolted, standard nforce4 chipset. Looks like you got some more high end stuff in there

Does anyone know where you can still get a quiet GTO? Looks like I'm a little late to the party.

It will be difficultto get a new one. You may have to search a used place.

Probably best bet now is the 8800GTS... otherwise I'd look at a 7950GT/7900GT with an aftermarket cooler.

Ah crap. I still cant get fan speeds working automatically. I flashed the card to a GTX to see if it would work like that, it does not. Kind of irritating. I have tried both editing the BIOS with nibitor and custom fan settings in RivaTuner. The only thing that works is "low-level fan control" in RivaTuner, but with that i can only set it to a fixed speed, and i can't get that to load with windows either...
