But powerplay mode only lowers them to 500/750 (default is 625/993). The cards run about 80c at idle. So these cards are idling about 30 watts more each than my HD 3870.
I dont know what everyone is talking about when they say the fan is quiet. Sure, when youre surfing the web, I cant hear the fans. But after about 5 minutes in crysis, those things sound like twin jet engines. They are actually loud enough to be heard over my 300 watt THX system. Something must be done! And they dont appear to even reach 50% of the fan speed. It appears under load that the temps are in the 90s.

The solutions is something you can do right now and would take you less then 20 minutes. Just reapply the thermal compound with something better like AS5 ceramic. Or, get yourself a Accerlero S1
(or whatever version they have now) and obtain a much better idle/load temps. Now the person who used that put a fan on so it wasn't silent cooling. Either way, the solution to your problem is in your grasp. It is up to you to decide how you want to go about solving it!
A. Re-apply thermal compound with better thermal compound
B. Use aftermarket cooler as most labeled for the 2900/3800 do fit on the 4800 series (hole placement on the 2900/3800 are the same on the 4800 from what I've read in other forums).
C. Do nothing
Which will you choose?
