hey people, ive been having problems with my 4790k, im not sure if its really a problem or it really is like this when it is on load, i was installing AC unity and i decided to check my cpu temp on core temp, i noticed that the temperature was going back and forth from 29c to 40 or higher and then it comes back to 29 all happens very quick. i provided a picture below please help me.

it changes temp in less than a second

Bhuck,

Intel's Specifications for Core temperature Digital Thermal Sensor (DTS) response time is 256 milliseconds, or about 1/4th of a second, so you can pretty much say that temperatures respond instantly to changes in load.

All very normal and expected.

Also, if you're going to run Prime95, make sure it's version 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...

Try prime 95 and monitor your temps like a hawk, make sure they don't get too hot.
Also if you are using the stock cooler I would upgrade to a cooler master 212 hyper EVO if possible and your case can take it. The stock cooler isn't really good enough for the 4790k especially if you are oc'ing.

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.
