I'm currently using an amd athlon x4 760k with a tx3 cpu cooler. I'm not overclocking... Back when I was using the stock cooler, I can remember cpu temps in the 90's and the lowest I've ever seen on the stock cooler would be 50 degrees celsius. Now with this aftermarket cpu cooler, the highest I've ever seen it go was 84 degrees celsius and the lowest was somewhere in the lower 40's. I know this is a improvement, but I'm still concerned about high temps...and I didn't even overclocked yet. Is this normal/stable?
