i7-7700K Overclock

[XBL-Revolution]

I was able to get my i7-7700K to 5GHz with 1.33Voltes. I get between 30-40C at idle but when I get my CPU to 100% usage I sit around 80C with a jump of 81-82C. I am able to run cinebench just fine with no crashes at all. When I run Prime95 it does not like to run properly (although I have never had any luck with Prime 95 doesn't matter even at stock speeds it didn't like to run properly) & I am able to game on it without any issues. I want to ask:

1. Are these temps okay?
2. What other stress tests should I run?
3. Anything I can do to bring the temps down? (I currently use a h100i V2)
4. How do I know my airflow inside the case is good?
5. Literally anything else I should know.

I would not be overly happy with 80c.

RealBench is a good one for more of a real world stress

de-lid the CPU and replace the TIM between the CPU die and the IHS

Where does the cold air come from and where does it go?

meh, ya done good.

80C is generally the maximum that people suggest a 100% load run at. I would personally monitor temps for a couple days doing the most intensive things you'd ever actually do with the PC, as synthetic benchmarks are really for stability tests and always produce higher temps than you'd ever see otherwise.

1. Temps are a bit high, but that is expected with that overclock. 

2. I don’t really think you need to run more tests. (But @knightslugger had a good reccomendation)

3. Maybe delidding would help it be cooler if you want to risk it. 

4. There are multiple ways to check airflow and set up fans, I’d advise you to do some research based on your setup.
