core i7 920 w/ hyper 212 plus

post #1 of 4
Thread Starter 
Recently I decided to replace my stock heatsink with the Coolermaster Hyper 212 Plus. Needless to say, my temperatures drastically improved; what I was seeing idle, I now barely reach under 100% load testing with Prime95. Unfortunately, I'm not completly satisfied.

core i7 920 bloomfield @2.66ghz (everything at stock settings except vcore at 1.05v)
Hyper 212+ with Arctic Silver 5 TIM (pea sized drop in the middle of CPU method)
6GB (3 x 2gb) corsair XMS3 ddr 1600mhz
corsair tx950w (was planning on SLI)
evga 58x sli mobo + bfg tech gtx 275 + 1tb samsung HD
all in a Coolermaster Elite 310 w/ front and side 2,000rpm intake fans

Now to my question, i've had the heatsink installed for about 4 days, and my core temperatures are as follows:
ambient temp ~24c
idle - 39, 36, 40, 35
Max during an hour of prime95 large FTT - 58, 55, 57, 54

Everything I've read on the internet from people with similiar hardware reported temps much lower than mine on stock settings. And the only reccomendations for people with higher temps are to reseat their heatsink.

But for my specific situation, when I took off the side of my case my core temps dropped about 5c while idle (slightly better 34,31,35,31) but I didnt test my load with the case off, so maybe I just have bad air flow? Also, my PSU is top mounted with its built in fan blowing down right in front of my main exhaust fan and partly directly into my heatsink as well. It also has a ridiculous amount of extra cables that basically fill 2 - 3 CD drive slots. This all leads me to believe that in order to see optimal temperatures I just need a better case with a bottom mounted PSU and that my thermal paste application / heatsink sitting are at least somewhat acceptable.

Are the temps im getting currently at stock settings with my bad air flow safe enough to being looking for a stable OC? (I only want to go to like 3.4ghz - 3.5) or do I need to spend more money on a new case/reapply thermal paste (using this technique) and try to get closer to my ambient temp while idle before I look to OC?

that seems perfectly fine

Thanks to Cacophony's second opinion I went ahead and put in an OC. Bus speed at 175MHz with Turbomode enabled for a 21x Multiplier for a 3.66Ghz core speed. Vcore and Uncore at 1.2v. Multipliers all at their minimums.

Idle: 42, 38, 43, 37
Max load: 71, 69, 68, 65

I feel safe with those temps for now, going to look for a better airflow case eventually though.

Also, my memory is only being recognized at 1400Mhz, the only way to get it to read 1600Mhz would be to OC my bus speed even further, correct?
