5850 reaching 75celsius

[jubeix90]

I have a 5850 running in a HAF 932 case. While running Crysis with all settings on High, CCC on my second monitor was showing 70-75 Celsius. Activity was maxing out at 100%. On idle, it's getting around 50 Celsius.

Fan percentage is staying around 25-30%, and won't go any higher, despite the increase in temperature.

Any idea how to lower the temperatures, or what might be causing this high heat? Or is this just normal for this card?

Also, is there a program I can use to change the fan speed manually? The ATI Overdrive feature needs to be unlocked, and I'm guessing the warning message means that it'll void the warranty, so I rather not use this method to change the fan speed.

Unlock it, it wont hurt anything. This way you can set your fan speed to something
like 50% or whatever you like.
They always give those warnings.

Plus ATI tools settings are limited for things like overclocking.

I just bumped the fan speed to 50%...

This thing is LOUD. I'm terrified to ever bump it up to 100%. Would this be unsafe?

No just loud. (well you might want to bolt your PC to the ground so it doesnt take off)
^^^^joke BTW.

Thats why i said like 50%.
Find you a speed that is fairly quiet but also cools good.

75'C is a normal, even your card can handle up to 100'C...
But for safely, just don't let your card above 80'C...
