My EVGA GTX570 Superclocked GFX card has some serious temperature issues. The Card idles at 36c and under load, playing games gets as hot as 97-105c, using 2 monitors the idle temp is 69-70c, while gaming still 97-105c(Crysis 2 1980*1050 all the bells n whistles on). The card is less than 8 months old, clean as far as i can see. I have removed the card and cleaned away any dust build up with compresed air, can't remove the plastic shroud because i dont have the proper security screw heads. Its not my case/air flow as airflow is optimal. 2 120mm front fans pulling also 120mm side fan pushing, 240mm top fan pushing, 120mm back fan pushing. My question is if i reTim the card will this help and if so whats the best thermal paste to use? I have Actic Silver 5 compound will this be sufficent? Also where can i get the security screw heads?
