As long as full load temps don't exceed 70C you're in the safe range. Not optmial airflow in case or higher room temps may result in slightly warm temps. 30-40C is the range for idle so you're good :)

Be prepared as most do not know this. The 4790K runs hot under load. Idle to real world loads run no more than 45'C with my custom loop. Then under Prime95 and OCCT loads the CPU runs hot no matter what yo do. At stock clock it runs between 60-80'C. If you overclock the temps will get upwards of 90'C and no matter if you reseat the water block or knock down the LLC it will still run hot. Myself and four others on here have run into probs with this.

And before the experts on here claim stuff, please look at my setup on my profile. I have 6 rads running my loop at ambient temps and I've reseated my CPU twice and changed out thermal paste as well. I've also changed out the inner flow plate in my EKWB Supremacy Full Nickel block to the one recommended for 1150 sockets to no avail.

The whole Haswell line runs hot under load, no surprise there. When overclocked they draw over 150W. With the small package and sometimes poor application of the heatspreader there are samples out there (like mine) that are just terrible at overclocking.

Supposedly they did a little better this time around with the refresh and came up with a better thermal interface. From what I have seen in the various posts people are averaging around 4.6Ghz @ 1.3v with the 4790k. I haven't seen any ridiculous samples like with Haswell where people were able to do 4.8Ghz @1.25v.

Interesting.

I used AIDA64 for my stress tests, which many say is overkill. But it does let you throw GPUs into the mix, which I like for testing my watercooling loop.

You can use P95, it just has to be an older version without AVX. AVX instruction set isn't really used during gaming, which is why it poses an unrealistic test for the average overclocker. However, if you plan to use the AVX instruction set for encoding/decoding then you would actually want to test it under those circumstances.
