HD 4870 - fan/cooling profile

I just bought a Sapphire Radeon HD 4870 and logged the sensors using GPU-Z while running 3DMark06. I noticed the GPU would reach as high as 71C while the memory would reach as high as 72C. It idles at 51C. Is this safe?

Rather than use a fixed fan value which would be noisy all of the time, is there any way I can tweak the automatic fan profile? Basically have it idle at X% and increase it up to Y% under full load? I don't mind a louder GPU fan under full load but having it run that fast all the time would be kind of loud.

What are some other alternatives? Just set the fan speed manually?

Believe it or not most cards with the default fan profile idle in the upper 70s, so yeah, you're fine.

First of all you do not have a temperature sensor on the memory chips, so the "memio" that GPU-Z reports is the memory controller temp on the gpu, so it's still a gpu temperature after all.

Like others have said, 71 C is rather cool. Break 85 C and then you can start to worry. If you still want a cooler card, install latest Ati Tray tools and under "overclocking" you have the fan profiles the card comes with. Change them as you wish and save them into a profile and make it load with windows. That is all.

Wait, you're not using the slider in the ATI overdrive tab?

I think the slider would set a manual fixed fan speed, which is not what the OP wants to do.

Ati Tray Tools is fantastic. I've only had experience with version: 1.3.6.1042 whilst using an x1950pro, so the fan profile settings might have changed since. I was able to set fan speeds for a range of temps.

ATI Tray Tools 1.6.9.1386 Beta

A google search came up with this which has support for HD4xxx series cards.

Good temps to you ^_^
