I5-3570K on stock clocks/Stock AIR. Running prime95 torture test with blend settings. Should I be getting almost 90C ?
Asus P8Z77-LK
Kingston HyperX Black 16GB DDR3 O.C from 1333 to 1600
MSI GTX 460 Cyclone (1GB) (not oc yet)
Temps taken using Core Temp 0.99.8

Edit: Reason It's here is because I'm about to be overclocking this processor, as soon as my watercooler gets in.

You'll be a much cooler cat, if you get the proper cooling, learn 100% what you are doing, and leave those other cats in your dust! :)

I think I broke it!

Is that with the stock cooler? It shouldn't get that hot, but I have heard the stock coolers are difficult to install. Did you take the tape off the bottom of it before installing? Is the HSF fully seated? Technically, that isn't harmful though.

Yeah, double check to be sure all four points are seated. Its easiest to do out of the case. Your cpu should not get that hot unless you have no case airflow. Watercooling will surely solve the issue. Even harder to install than Intel's crappy heatsink but much more effective. I can easily run my 3770k at 4.5ghz and temps never go above 80C with a fairly simple H20 set up.

Everyone makes mistakes, even the most seasoned veterans mess up something once and a while. Just keep an eye on those temps. Corsair makes good AIO coolers. I went with the Zalman 320 as it was cheaper and really just as effective and then added dual Corsair high pressure fans. Either way, you new cooler when installed correctly will work so much better than the stock unit.

Intel heatsinks are the worst design, period. You would think that Intel could surely design something just a little bit better. Check to make sure all 4 pins are securely snapped into place, proper amount of thermal paste, the usual. But its pretty easy to not get the heatsink on straight and secure with their idiotic 4 pin design if you are not careful about the install.

I'm beginning to wonder if Core temp isnt reporting incorrect temperatures.... I'm idling at the desktop trying to boot farcry 3 and my CPU temps according to it are fluctuating wildly between 42-50 C

Why are you running Prime95 on stock settings and stock cooler, you don't need to run P95 on stock settings if you fail at stock settings you probably have a bad CPU or shortly will have at those temperatures.

Prime95 is basically used to seriously stress your CPU to discover overclocked stability, but that's done with overclocked settings using a good aftermarket cooling solution!

Wait for your aftermarket cooling then worry about Prime95.

Where did you get the idea that was the thing to do?

There is no need to run CPU stress testing programs with stock settings and a stock cooler, what you can and cannot do will dramatically change once you have a cooling solution that will allow it.

Those temperatures are perfectly normal for the cooling you have!

The reasoning behind reaching those temperatures just for curiosity is irrelevant.

Keeping your CPU as cool as possible no matter what you are doing with it should be your goal for longevity of the CPU.

So get your water cooler first, then stress test at stock settings till your hearts content.

But hey, don't listen to me, do what you want!

I personally had this almost exact problem with temps. It came down to one of the 4 push-pins on the heatsink not seated tightly. In the process of trying to fix it, I actually broke off a piece of the pin so I had to settle for an aftermarket heatsink in-store I didn't really want.

You should not risk OCing with the heatsink you have installed. I'd recommend a coolermaster hyper 212 or better.

KK so I'd like to report that I've installed all my stuff and running prime95 to stress my CPU to see how hot it gets... 60's avg with H100i. 4Ryan, I can see you're invaluable help around here, so let me designate you as the answer. Thank you all, you've been helpful in at least some small way. And the heatsink I got for my i5 was puny compared to my 8-10 year old Core2Duo (i don't even know the model of it, but that one's heatsink was twice if not 3 times as large as the one for the i5.)
