I decided to try out the COD:Ghosts free weekend on steam today. I've had my new GPU installed for close to a week with no problems whatsoever. Even running high end games on Ultra have not effected it in the slightest. However after playing close to 3 hours I took a break. Went back on twenty minutes later, joined a match and midway my GPU started a long nonending beep. I immediately shut the game down, the beeping stopped. I brought up my program to check tempature and the GPU was at 121f. It cooled down to around 80f within 3 minutes of closing the game down. I'm not sure if it's the different place I had to stick my case fan and I'm not getting adequate airflow to the case, or if it's a problem with the GPU itself. Any help would be appreciated and I will answer any questions to get this fixed pronto.
