luckily we could just edit the XML file.

Yup - all 6 of mine were right around 77C in an air-conditioned area with the case open. Ugly. Just putting your hand near the card was scary

Yeah, will be getting the TRad2 once it's released..Should perform much better (and smaller too) than the HR-03 GT. Even the dual slot 4870 is having same problems too with the heat :/...the card is like running at 80c and the fan only at 24-28.

My Sapphire 4870 runs 80°C idle at stock settings. Fan speed just above 20%. Something had to be done

RivaTuner was the perfect solution for me. No modifications to the card or losing your warranty. I simply tested several fan speeds and found 25% good and silent idle speed, 40% solid 3D speed and 45% if things still got too hot.

Fan speed couldn't do the trick by itself so I tuned clock frequency profiles too. 2D clocks are 400MHz/500MHz (core/mem) and at 25% fan it meens around 55-58°C temps. Nice drop from stock

3D profile bumbs clocks up to 800MHz/1020MHz and fan speed 40% keeps it under 80°C.

RivaTuner monitors hardware acceleration and if it's in use -->> 3D profile kicks in and if hw acceleration is not in use -->> 2D profile is in use. Simple

...the new Catalyst driver is supposed to have fan speed controls built in now. Haven't tried it yet...

Lacus · 19th Oct 2008, 04:16 PM

well, yeah..The lastest CCC 8.10 supports manual fan control

. Btw besides using rivatuner, 1 can also modify the XML profile for the fan speed. Techarp did a article on it anyway

...Awaiting my new cooler for now

The fan speed control in the new catalyst drivers is pretty good. You can skip having to use any third party programs, and any XML editing. All of that has been rendered obselete by this driver release.
