After I got my Step Up card from EVGA (a 7900GTX EGS 5 12MB), I removed the heatsink/fan and cleaned up the stock goo/thermal compound and applied AS5. The first day or so, I ran some video stress test and the highest temp it reached was around 68. I thought that was on the higher side, but still normal. I let it set for a few days and since then, the highest it has reached during stress testing is only 54. I think the AS5 finally works like it supposes to. Don't know what yours temp is, but I would like to know what kind of temp you are getting whether you've applied AS5 on yours or not. Mine is still using the stock heatsink/fan, so I think it's a good temp as of now. Was think of buying aftermarket cooler(s), but if the stock cooler this good, then I am not gonna waste any money for that. Tell us yours if you have couple of minutes. Thanks...
