Heydillyho!

I just bought a Power colour 4870 x2 last week and have some general questions about coping with this thing.

First up is temperatures, case temp is about 25C and idling at the Windows desktop GPU core 1/core 2 are sitting at 88C/70C, with automatic fan control holding steady at 27%.

Now after playing Crysis the temps were about the same on exit and the fan was working considerably harder.

So I manually set fan speed to 40% and core temps fell to 40C / 30C so I'm happy with those numbers. Question is, does disabling automatic fan control mean I risk damaging the card in stressed situations ?

Is there anything I need to do to ensure both cores are working happily in games? I checked Catalyst AI is enabled and set to advanced.

If you guys have any other tips they would be much appreciated.
Thanks!

Fans will still spin up to keep temps from going to high even with manual control and as long as catalyst ai is enabled nothing else you can do to ensure crossfire is working.

Great thanks!

So the fan will auto speed up. Thats good news, then I can set a minimum fan speed that is a trade off between cooling and noise and not have to worry about frying the card.
Thanks for the help!! :)

I use 35% for desktop and 40% for gaming usually.

Note that the fan will only speed up when it goes 90C+ or so.
