I got 3.8 ghz at 1.285V with load temp of 62/60.
Too hot? or good?
Is that a stress test max temp or a gaming load temp (these will be different in most cases). Just for comparison. I try to not allow my max temp on my 24+ hour stress/stability test to go above 60c. The max on the OC you see in my sig is 58c in a room that is at 75f. My gaming load on a game that stresses it such as Crysis or UT3 is anywhere from 50 - 54c depending on load and room temp at the time.
Hopefully this helps you to compare. If your temps are at 62c while doing a long stress test then imo you are fine, but if that is just while running a game I would try and see what can be done to get that a tad lower. Just my personal preference. From a technical aspect you are within the limits, but are starting to hit the borderline.
When you say you want to keep it for a LONG time...how long is that exactly? For me, 2 years is quite a long time, but for others 4 or 5 years is, so what are we lookin at here?
