Intel i5-6600k Overclocking/Heat Questions

--Info:--
i5-6600k OC'ed to 4.7Ghz
Cryorig H7 CPU Cooler
Artic Silver 8 Thermal Paste
ASUS Z170-A MOBO
All temps will be referred to in Celsius
--Programs and Settings:--
AIDA 64 Stressing CPU and FPU
I did not Manual Overclock I used ASUS's 5 Way Optimization
Realtemp
--Results--
When running AIDA 64 for 15 minutes these are the results I got:
0-5 minutes in, max was around 80 degrees for mere seconds before CPU fan kicked in and cooled things down to around 75 degrees.
5-10 minutes in, Temps in between high 70's to mid 80's (CPU fan kicked in full power) spiked up to 88 for a few seconds
10-15 minutes in, Temps averaging in the low 80's, Spiked up a few times to 90 for mere seconds.
--Questions--
Are these Temps normal for the program, overclock, CPU, and Cooler? Should I be worried or not knowing that ASUS's Program did Auto-Stress tests and said that this was okay?

  1. Those temps are too high for comfort. You should really strive for an overclock which does not exceed 70C (for a 24/7 OC) while under extended stress testing. This allows you a little thermal headroom in case the ambient temperature rises or the cooler starts to collect dust. You really need to manually overclock as auto overclocking generally raises the vcore higher than needed to ensure stability.
  2. Best answer
    It is no surprise at 4.7GHz that your system is overheating using a Cryorig H7 CPU Air Cooler.

    If you wish to continue using a Windows based optimization program then try reducing Core Voltage a little at a time till the system is no longer stable in AIDA64. Reducing Core voltage will create less heat being generated. If you cant get it stable at current frequency and Core voltage, then drop your frequency or upgrade to an AIO Water Cooler that's big enough to handle your OC and will fit into your Case.

    You will degrade the CPU at those temperatures if sustained.

    I never use windows 3rd party software to OC and the same goes for ASUS's 5 Way Optimization.
    You should use the Bios only to OC.

    I have lowered my core voltage to 1.345, and lowered the overclock to 4.6Ghz.
    Temps are averaging low 70, with the highest peak being 77 for a few seconds.
    You were right about the auto OC. It gave it more voltage then needed. So I think I am at an okay point. Let me know what you guys think.
  4. Still a little high, but in all reality, you will likely never see those same loads while gaming so you should be okay. You may want to monitor with MSI Afterburner occasionally.

    Yeah, I'm using RealTemp. The most CPU intensive game I play is Arma 3. So I'm going to check when I start playing that.
    Besides gaming, I only render a few videos, and stream (while gaming of course).

    Agreed however rendering Vids is intensive so keep an eye on your temps and you should be OK.

    Yeah thats what I was thinking. However I typically only render with GPU. But I might start with CPU depending on times and temps. (Sony Vegas)
  8. To anyone looking at this thread in the future. I figured out my main issue with heat. I decided to resit my Cooler for the heck of it, my cooler either wasn't tight enough, or was sat wrong. Now sitting at a stable OC of 4.6 Ghz averaging High 50's to Low/Mid 60's sometimes spiking to 70 under FPU and CPU load in AIDA 64.
