Hello everyone,
I'm having a issue I guess with the temperatures of the CPU.
With the stress test, cores are reaching about 80/90° and it's a lot.
And idle temperature is around 35/40.
I have an Intel Core i7-4790K
ASUS Z97-Pro Gamer
2x8 Corsair Vengeance 1600 mhz
Cooler Master Seidon 120V as cooler.
I've tried to put the turbo at 4.4 but it causes overthrottling, that's why I lowered to 4 ghz without turbo.
Here's the image which includes the voltage and temperatures: http://imgur.com/a/mzGwL
What should I do?

Well, you considerably enlarged the cooling capacity with that new cooler.
It's a bit unfortunate that you haven't posted that you intend to replace the cooler.
those are way better (for future): https://www.ekwb.com/shop/ek-xlc-predator-240
this 80C for cores under load with prime are really fine.
you can re apply the thermal paste, delid the CPU and apply decent thermal paste between the silicon and heat spreader.
With all that done + maxed fans in pull-push on rad + max pump speed - i doubt you will be able to go below 70 (most probably 75+) when prime95 is running
 


The blue led is on, so I guess its working


Auto voltage, round temperature probably around 25C, 28.9.1.0

 

I already reapplied the thermal paste and still at 80c. I'm not going to delid since I'm not that expert about it.
 

I used AIDA64 as stress test
 


Dat_Lucky,

Thanks for the info. Here's the normal operating range for Core temperature:

80C Hot (100% Load)
75C Warm
70C Warm (Heavy Load)
60C Norm
50C Norm (Medium Load)
40C Norm
30C Cool (Idle)
25C Cool

Core temperatures in the mid 70's are safe, so you want to keep it under 80.

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

Core i 2nd through 6th Generation CPU's have AVX (Advanced Vector Extension) instruction sets. Recent versions of Prime95, such as 28.9, run AVX code on the Floating Point Unit (FPU) math coprocessor, which produces unrealistically high temperatures. The FPU test in the utility AIDA64 shows similar results.

Prime95 v26.6 produces temperatures on 3rd through 6th 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 significantly 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 Core Temp to measure your temperatures - http://www.alcpu.com/CoreTemp

Your Core temperatures will test 10 to 20C lower with v26.6 than with v28.9.

Thanks for the answers. The problem was the AIO it self. I changed to Corsair H115i and it works PERFECTLY. Now I can use the turbo 4.4ghz and with the stress test its around 65c. I can even overclock more but I don't need it. Thanks again.
