Yea cooling is alot ebtter these days. Ive had that happen to a K6 before lol. But as to the 75f comment, if we make our house any colder than 79 then the electric bill goes crazy cause the AC has to run more.
i solved my problem! lol.. i took the fan off my old CPU heatsink and placed onto the GFX heatsink (after applying rubber feet..) and it work perfectly my temps dont rise above 57
