Hey guys I've been struggling with my i7-4770 for the past year, when gaming temps would reach 80c on a couple cores with the rest at around 73c, which I know is too hot for gaming compared to others, the reason I thought was because I was using some cheapo $10 aftermarket heatsink, so I just today upgraded to a hyper 212 evo.

To my disappointment gaming temps still reach as high as 74c on a couple cores with the rest being 68 which is not as high as the 80c but still I hear so many people talk about gaming with the hyper 212 evo on their i7's and how it never goes past 70c, also I tried prime95 stress testing and after 7 minutes all my cores were at 100c, mind you this is also slightly better than my previous heatsink where it would hit the 105c danger in like 2 minutes.

What am I doing wrong here? I use mx-4 arctic thermal paste and I do the pea drop method btw if that helps.

The pea method is pretty inexact - if you're using an amount equal to the size of a real pea, you're probably using too much. Too much paste acts as an insulator and prevents efficient heat transfer. Try pulling the cooler and looking at the paste distribution. If there is paste that oozed out over the edges of the CPU lid, after you've cleaned it off and allowed it to dry, apply new paste but use a bit less than previously. Also, make sure when you're remounting the cooler that you seat it squarely without a lot of adjusting and especially not lifting and reseating. Tighten the screws evenly in a criss-cross pattern and make sure they're seated snugly.

It may take a couple of tries to find the sweet spot with paste amount and...

It may take a couple of tries to find the sweet spot with paste amount and mounting technique, but practice makes perfect :)

I'd say the amount I used was about the size of a real pea yes, so maybe I did put too much... but I believe I did a good job with the seating with only minor shifting to line the screws up and the tightening which I did in the criss cross pattern.

Am I better of spreading evenly? If I continue to do the pea method how small should it be?

MX-4 is good, but you're running the wrong version of Prime95.

Do NOT run any versions of Prime95 later than 26.6. Here's why:

Core i 2nd, 3rd and 4th Generation CPU's have AVX (Advanced Vector Extension) instruction sets. Recent versions of Prime95, such as 28.5, run AVX code on the Floating Point Unit (FPU) math coprocessor, which produces unrealistically high temperatures. The FPU test in the software utility AIDA64 shows the same results.

Prime95 v26.6 produces temperatures on 3rd and 4th Generation processors more consistent with 2nd Generation, which also have AVX instructions, but do not suffer from thermal extremes due to having a soldered Integrated Heat Spreader and a 35% larger Die.

Please download Prime95 version 26.6 - http://windows-downloads-center.blogspot.com/2011/04/prime95-266.html

Run only Small FFT’s for 10 minutes.

Use only Real Temp to measure your Core temperatures, as it was designed specifically for Intel processors: Real Temp - http://www.techpowerup.com/downloads/2089/real-temp-3-70/

Your Core temperatures will test 10 to 20C lower with v26.6 than with v28.5.

Please read this Tom’s Sticky: Intel Temperature Guide - http://www.tomshardware.com/forum/id-1800828/intel-temperature-guide.html

Also, what is your ambient temperature?

Thanks,

CT :sol:

Thanks for the advice! I ran both programs you listed and with the small fft test for 11 minutes realtemp listed max temps of 76, 82, 77, and 73. So I imagine this is better then? Also my ambient temp is 21 Celcius.

You're correct I hadn't gotten around to re-pasting yet, so with proper testing looks like its not as bad as I thought, but you think it could be lower with a smaller amount of thermal maybe? What do you think a reasonable range those temps should be if a max of 82 is still a little high?

Mobo is a ASRock Fatal1ty Z87 Killer.

My case is old I think, but its an Ultra brand Wizard Mid-Tower Atx black case. I have an extra fax hooked up at the back of the case as well for extra cooling.

Fixed! I think it was a combination of the bios and poor application of thermal, it took me two tries to get it right but I did a pretty small grain of rice in the middle and updated my bios and after twelve minutes of stress testing my hottest temp was 67 with the rest around 63, much better than the 82 I was getting before!

As for the bios I realize I never updated it beyond base version and the first update it had gave it compatibility with 4th gen Intel. What changed was my stock i7 was always at 1.28 volts which I learned is way too high for no overclock, when I updated the bios it's now at 1.007 volts. Thanks for the help :)
