That bit blew me away..
But I guess this monster needs proper cooling.
That's a vacuum cleaner called FX. Even a standard 120mm cooler uses only about ~0.5 amps.

FWIW, the stock X1800XT/X1900XT fan uses 0.42 amps. An 80mm Delta EHE 80 cfm fan typically uses about 1 amp. The 100+ CFM Delta UHE fans run around 1.5 amps. I've got the EHE hooked up to my X1800XT, it sure makes a lot of noise that can be heard clear across the house when I crank it up. This 2 amp blower will probably make the hard core OC crowd smile.

Just because that is what it's rated at, it doesn't mean that is what it will be running at. If ATI's cards of the last few years are anything to go by, the fans will not ever be running at 100 percent, and so will not be anywhere near as noisy as you seem to think.

I thought you had all the details big boy...
Join the B3D circle jerkers and you'll get all the details.
Big boy? what is that about?
I'd be worried if it uses even remotely close to 50% of it's max power - even if it's in gaming-situation. And if it doesn't never use it's maximum potential, then what's the point of putting a fan like that there?

As long as the cooler is dual slot, I really dont care. IMO the cooler is sexy and crossing fingers on good OC'ing. That heat sink looks mean.

Most fan noise nowadays is caused by airflow noise. A big fan running slowly is quieter than a smaller fan running faster. Obviously in the event of a very hot environment, the fan can speed up, but unless you regularly game in 40 degrees C ambient temperature, I doubt it will end up going that fast in normal use.
I don't run around replacing 120 mm fans with 60mm versions because the 120 mm ones never need to run at full speed.
Umm, am I the only one that was hugely annoyed by the up-spin/down-spin syndrome characteristic of the X1900XTs stock cooler?If the darned thing would just go up to a certain speed in 3D and stay there(at worst, increase it if it gets super hot) it would be cool, but the up/down/up/down dance of the fan is unnerving.
Yeah I bitched about it a lot and got the expected "I don't hear it so you must be imagining things" responses from some people

Actually some of the bitching was the case was on your desk and open -- if my memory serves me -- /runs!

Yeah so
I've found that a lot of the newer, cleverer fan designs are fairly inaudible when the case is closed. They are pretty much tuned to make any noise at the kinds of frequencies that don't get through cases. Kind like a low whirr that dies when the sidepanel is on, rather than the older-style whine that cuts through cases.
Though I suppose if you've got the sidepanels off and the case open in front of you, then you can't really care about the noise that's coming out of it - if you did you'd close the case!

Perhaps that is so, but it shouldn't have to be that way.
I imagine me and him are not the only peeps whom run with our cases open (granted mine is on the ground) because we're messing with crap (mostly the CMOS ) so often that the side panel becomes a hindrance. A constant fan would be nice, even if slightly louder, if it doesn't spin up/down depending on every little load. That shared irritant is why I just set mine to a constant in ATi Tool. If R600 is capable of needing 100% (24V) ever from that fan, you can guarantee it's going to be ramping again from stock, as that fan is going to be loud,annoying, and prolly take out some pinkies.
Irregardless, I just hope we see some decent blocks closely following the release. If it's true that this PCB will also be used for the R700 gen, at least it would give me (and others) some incentive to put it on my loop and forget that worry all together without having to buy another one next gen.

Well like I said in that other thread I'm not really concerned with what it should sound like with the panels on. All I'm concerned with is the fact that I've had other cards in there with the panels off and have not experienced the same annoying fluctuations in pitch. Moot point now of course since the stock cooler has been replaced
