My 4790k is getting 84+ degrees with a Hyper 212 EVO.

[Finijumper]

A few days ago I bought a PC with included mounting parts and running prime95 gets me to the 84 degrees. Is this normal?
I have a Hyper 212 EVO completly new.
At idle it is at 40 degrees.

Sorry for my bad english, I'm spanish

Not normal. One question, do you overclock?

If it does not improve your temperatures, I will be here to help you.

Thanks. Running some minutes prime 95 is getting 90º. You can see it here: http://prntscr.com/7mcwnq

Alright, I can see you have done a small overclock of the CPU, however it is so small that is should not have that impact on temperature.

I still suspect a faulty installation, read my link and reinstall the EVO. Then run Prime95 and see the difference.

I didn't do that small overclock, the people who mount the PC did it. They don't put the termal paste in the box of the cooler 🙁

Finijumper,

What is your ambient temperature?

Which version of Prime95 are you running, and which test? Blend? Small FFT's?

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 extremely high temperatures. The FPU test in the stability testing utility AIDA64 shows similar results.

Prime95 v26.6 produces temperatures on 3rd and 4th Generation Core i 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 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 20C lower with v26.6 than with v28.5.

I was running version 28.5 :/ My ambient temperature is 22ºC.
With 26.6 version the temperatures are this: http://prntscr.com/7mdpqz http://prntscr.com/7mdpuy
Are they good?

 

[CompuTronix]

Is that Small FFT's?

Yes.

Your Core temperatures are within spec by just a few degrees.

Keep in mind that Prime95 v26.6 Small FFT's is the "go-to" test for establishing a thermal baseline, because it's a steady-state 100% workload. Stability testing is a separate issue.

For 22 nanometer Core i 3rd Generation Ivy Bridge and 4th Generation Haswell / Devil's Canyon processors, the accepted recommendations are to keep Vcore under 1.300 and Core temperatures under 80C.

Intel desktop processors have thermal sensors for each Core, plus a sensor for the entire processor, so a Quad Core has five sensors. Heat originates within the Cores where Digital sensors measure Core temperatures. A single Analog sensor under the Cores measures overall CPU temperature.

Core temperature is 5C higher than CPU temperature due to sensor location. Intel's Thermal Specification is "Tcase", which is CPU temperature, not Core Temperature. Tcase for the i7 4790K is 74C. Tcase + 5 makes the corresponding Core temperature 79C. <-- This is your spec.

At 22C Standard Ambient, here's the typical 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)

The relationship between Core temperature and CPU temperature is not in the Thermal Specifications; it's only found in a few engineering documents.

my 2 cents:
check if your motherboard has multicore enhancement turned on (go to BIOS at startup, then mobo's cpu settings or advanced cpu settings). most have it on by default. if it's on, disable it. in addition to that, try enforcing a bit more aggressive fan profile on your cpu and case fans if possible. see if it helps with the temps.

and what others said.

i have an evo. but it's not really adequate, on it's typical fan profiles, for an i7 4790k.
