Overclocking CPU Temps too high ?

    I've recently overclocked my i5-760 to 3.8GHz and noticed the temps were much higher than I expected, can anyone tell me if these are normal or not ?
    I'm using the thermaltake frio to cool my system and I'm starting to wonder if I've not used enough thermal paste or may have set it up wrong.

    Have you lowered voltage as much as you can without losing stability?

    I've lowered them to the recommended settings that I've read online.
    CPU Vcore at 1.35V
    PCH core at 1.14V
    DRAM at 1.64V
    CPU PLL at 1.9V

    Try to knock the OC down to 3.6 and see what happens.

    There are quite a few things which can reduce temperatures. Make sure you haven't put too much thermal paste on the CPU (a rice grain sized amount is usually enough), make sure your HSFs are blowing air in the same direction (preferrably out of the case through the rear case fan), and do make sure you lower the voltage as much as possible without sacrificing stability or frequency.

    Something doesn't look right, 70C-78C after 3 minutes of Prime95. The first thing I would check would be that the fan(s) is/are on the right way round, the thermal paste is applied correctly and the Frio is mounted right.

    One of the fans actually WAS on the wrong way and that's now been sorted, the temps are still quite high though at 74, 75, 69 and 77 degrees.
    I've got what I think is the right amount of thermal paste on so I'm clueless as to why the temps are so high.

    I wouldn't call that excessively high, I get low 70's on my rig on prime 95 with quite a high overclock. Now if that was going into the 90's I would say start to panic, but even then your chip can take temps that high. Your low temps are a little bit high, but they're not the ones you have to worry about. Also, it's pretty hard to push a PC to run temps in the mid 70's constantly, prime is designed to give everything a right good kicking. if I push my rig really hard it might hit 57 degrees for a short while. I would guess your would be about the same. The main thing is that you've got a stable overclock., which I'm guessing you have.

    Those temps are fine.

    20'C from TJ Max isn't a problem when stressing the cores with Prime although I would start to reduce the vcore until you get instability, then increase it to the last stable figure. Doing this might give you a degree or two...

    What kind of case have you got this in? Has it got plenty of air flow?

    I'm using the Thermaltake Frio in the Corsair 600T, a pretty awful case for cooling but I didn't know that when I bought it.
