4790k Safe Temps?

So after installing a custom water cooling loop over a year ago I am finally getting around to OC'ing my 4790k. I have done some OC'ing with my old Phenom XII 965 BE but never really toyed with an Intel chip. I tried using my MOBO's easy tweaker which bumped it to 4.5 (101.99 x 45.) @ 1.7W. I put it through Prime95 for about 10 minutes and it got up to about 85 celsius running 8 iterations while it idles at about 30. Are these safe temps or should I go in and toy with my settings and voltage on my own?

ASUS ROG Maximus VII Hero
G.Skill Ripjaw Z Series 2133 (stock values)
EVGA GTX 970 FTW (stock values)
EVGA Supernova 850 G2 Gold

ericlplante,

There's a Sticky at the top of the CPU's Forum you should read: Intel Temperature Guide - http://www.tomshardware.com/forum/id-1800828/intel-temperature-guide.html

Do NOT use versions of Prime95 later than 26.6 on 2nd through 7th Generation i3, i5 or i7 CPU's, which all have AVX (Advanced Vector Extension) instruction sets. Recent versions of Prime95 such as 28.9 run AVX code on the CPU's Floating Point Unit (FPU) which causes unrealistic temperatures up to 20C higher. The FPU test in the utility AIDA64 shows similar results.

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

Run only Small FFT’s for 10...

Use Core Temp to measure your temperatures - http://www.alcpu.com/CoreTemp

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

Here's the recommended 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 up to 80C are safe.

I thought my temps seemed a little high do you recommend a different stress testing program that would be more accurate or have a link to a good version of prime95?

*edit- just read the entire post more carefully lol, thank you
