2600k/H70/Prime95 Small FFTs/73c - normal?

post #1 of 12
Thread Starter 
Just got done installing the H70 into my system. After installing it, I went ahead and did an OC to 4.5 @ v1.3. My idle temps aren't too bad (usually around 30-35c), but my load temps while running Prime95's Small FFTs test is a little distressing. After about 30 minutes or so, these were my temps...

Core 0: 65 (highest was 65)
Core 1: 69 (highest was 71)
Core 2: 71 (highest was 73)
Core 3: 64 (highest was 65)

If my vcore was like 1.35 or something, I wouldn't be questioning these temps, but for a vcore of only 1.3 with an H70, that seems a little too high. I've tried reseating the H70 like five times now, and I've used a couple different thermal pastes (AS5 and some XIGMATEK stuff that came free with the H70 purchase). Temps stayed exactly the same every time. I also tried doing a whole bunch of different techniques too, when applying the thermal compound...

-Tiny dot in the middle of the cpu

-Thin vertical line down the middle (as AS5 recommended)

-Spreading the thermal compound with the spreader thing that the XIGMATEK came with

Again, no difference. I also have the H70s fans hooked up to the PSU, so they're running at full speed all the time (as an intake push/pull too).

So, are these temps normal or something? Or is it possible this unit could be defective?

I have about the same temps myself.

If it makes you feel better you most likely hit right about at your highest temps if you ran it for 30 minutes. Its the 2nd set of test that run, usually after 10-15 min or so, that you hit higher temps. At 1.3v that sounds about normal, AFAIK, with that cooling solution.

Ah, okay then. Have to say I'm a little disappointed in the H70's performance, but I'm relieved to hear that these are within the normal range for this setup.

When I originally installed my H70, I installed it on top of a DOA cpu that I ended up having to RMA, so I had to clean off the thermal compound that came preapplied on the H70 and replaced it with the remaining AS5 that I had. I never really got the chance to see how much better the preapplied stuff is in comparison to AS5, but I've heard that it is better. I also heard that it's that Shin Etsu stuff (is this the same one?). Would it be worth it to buy that stuff and replace my AS5 with it? Or do you think I wouldn't see too much of a temp decrease?

What are your ambients like? My 2600K chips don't usually break 80C @ 5.0ghz and 1.48v with H70 cooling units.

Perfectly normal, Although watercooled the h70 performs like a top end air cooler

My 2500K@4.5GHz ~1.368v Vcore tops out at about 70c for hottest cores when small FFTs. This with a CM Hyper 212+.

What tim did you use out of curiosity because i have basically the same setup however im not getting those temps...( i used as5)

The same type chips can be different for temps as well, some run cooler & some are hotter. Ambient temps can also play a big role, as well as airflow in the case , etc.
TIM can make a difference of a couple C°, but as long as the tim is applied right & the heatsink has good contact the tim should not make a large difference.

I use the stuff that came with the 212+. What temps are you getting?
