Just added one more fan still the same problem. Should the fan blow to the cards or away from the cards?

Two 6990 and GPU0 high temp

Hi everyone my first post here.

I have run a mining rig now for month with two 6990 working fine on Ubuntu 11.04. Now I see a problem with GPU0 with high temp and unstable hash rates but GPU1,2,3 is stable and not running over 100C temp. And also when GPU0 reach 100C clock speed drops to 500Mhz and GPU loads flips between 0 and 100%
Is possible I have overheated one GPU on the card if so how do check this? Or any other tip?

Code:
Adapter 0 - AMD Radeon HD 6990
            Sensor 0: Temperature - 103.00 C

Adapter 1 - AMD Radeon HD 6990
            Sensor 0: Temperature - 69.00 C

Adapter 2 - AMD Radeon HD 6990
            Sensor 0: Temperature - 74.50 C

Adapter 3 - AMD Radeon HD 6990
            Sensor 0: Temperature - 71.00 C

How long did your $20 credit last you? I picked up my Radeon 5670 for $59 and it's giving me 85Mhash.... I guess this Amazon GPU service is am crummy as people say.

It lasted 9 hours so not a good deal for the 0.38BTC I got Smiley But is was a free 20$ voucher.

Thank you working well now I have a use of my 20$ Amazon voucher. Just need stop it when the Amazon credit is spent Smiley

I can also confirm the flowing hash stats on Amazon EC2 GPUs.
70Mhash/s per GPU with a total 140Mhash/s
