Best method for 4870X2 fan speed changes

[Bucklaz]

Oh, I notice alot of people are flashing to an ASUS 4870 bios, as that one comes with an adjuster

I'm sure you already know of this but I have to mention it...the newer drivers have the fan speed control so you can manually change it. Is that too manual of a way in comparison to what you're trying to get? Notice you're looking for a more automatic way.

[confusion]

The ASUS bios has an automatic function, along with Manual fan speed, and another section for fan speed based on temp.

I'm using the latest RivaTuner with my 4870x2 and it's working flawlessly for me.

Fan is at 26%, idle, temp around 48-50 celsius, and on heavy load, fan rarely goes over 34-35%, and never over 58-60 celsius.

Who said those 4870x2 were hot and noisy?

[Bucklaz]

holy smokes Levesque. Aren't those temps kinda high? and those fans kinda low?

I don't know much about gpu temps, or actually temps in general, but i would have thought a 30-40 idle temp would be better all around.

I don't notice a difference in noise from 20% to 50%, why'd ya set yours so low? Does it save power?

[confusion]

That's about the same fan speed and temps I currently run for my 4870x2 too. No prob running those temps for a GPU. I could crank up the fan speed higher, but since I never really go over 65C on load with the fan, I don't see the point.

I am putting this under water as soon as I get the chance. I've got the parts, I'm just taking my time. It isn't noisy, but it isn't quiet!

The R770 GPU's are designed to idle at temps of 60C-80C, and load at 90C-110C. It sounds hot and bad, but the chips can take it .

Thats not to say of course, that you shouldn't keep temps down, as it will extend their lives, but 50C idle, and 60C load really is nothing for the chips.

[Bucklaz]

thats great news! was idling at 40c with 40%fan. I think I'll decrease the fan to the same settings as the 4870x2 guys

also: anyone get that lame User Account Control pop up everytime you start vista, cuz of riva tuner trying to load up.

I read that aside from 3rd party programs, there really is no way for vista to allow user selected programs to bypass the freakin thing without disabling UAC all together.

[confusion]

Yeah I would get that prompt everytime too.

UAC is the only thing I hate about Vista. Luckily, you can turn it off. My version of NOD32 has a similar functionality that actually works. I'd recommend going that route and disabling UAC.
