Overheating? Do you know the temperature your getting before your card has to be shut down? What about airflow in the case? Have you tried running the tower for a few hours and seeing it's performance under regular load?

Don't set the fan on automatic, there are programs are there to set the fan speeds to whatever you want based on certain temperatures. Automatic tends to suck with ATI cards.

If increasing the fan speeds and maybe putting in a 120 mm in the case to maximize airflow doesn't work, then you have a problem.

Get some case fans, without a doubt.

Get the latest drivers, and then manually set the fan speed to 80% or higher.

My 4850 runs at 675/1100 @80% fan speed@45C

i wouldnt wanna run the stock fan at much higher than 80%... at that point it starts sounding like a hair dryer too... i found 65% was enough with the stock fan (and relatively quiet), even with a modest OC... you might wanna use 80% during heavy gaming tho

Are you comfortable with flashing your bios? You can change the stock fan profile to something better...

Or just control it manually with CCC

Check your cpu temps, maybe it's not the gpu.
