90c seems high, at that point you would most like seeing warnings from that the processor is running hot. I don't think I have hit 65c with my Intel® Core™ i7-2600K even with the stock cooler and with the 212 + with 2 fans in a push/pull I am right now there with popatim.
only like 2deg difference at idle, at full load i notice no difference.
And this case has some BIG fans too so case flow should be good.
I disable PLL overvoltage and disabled Marvell controller (found that helps with boot times, not really relevent to topic i know)
Disabling PLL overvoltage did not help, my temps still rise like crazy from idle to about 60deg in a matter of a sec or so, then gradually over 10-15 secs hit 80ish and thats where im shutting it off now.
Watched CPU-Z for the last 2 runs on recomendation, when Prime starts doing its thing max voltage to core is 1.304,
at idle its about .976 - 1.04
Since I did have a bit more faith in an Intel sponsered HiPo cooler I went ahead and OC'ed to ~4.5ghz
I have the radiator in a push/pull setup, thanks to the fan from the Hyper EVO I was able to add that puller
Tested in Prime95 I got max 64deg after 15 mins reported through Coretemp
Small FFT's I got max 65deg , Large FFT's max 62deg
Also tested with passmarks burn in test v7 pro
CPU test at 100%
avg was 59deg max was 62deg
Overall im verry happy now, before on stock clocks in less than a minute I got over 90deg with the Hyper212 evo.
NOW TO NOTE: Im not saying its a bad product, mine could have been faulty, not sure how, but the possibility remains.
Thanks to all that have helped, but I now know the true culprit WAS the cooler that I had on it to begin with.
Im VERY happy with the Intel liquid cooler though, even on an OC its performing stellar!
