i7-6700K 4.5GHz OC
Hi, I just bought a new PC and wanted to upgrade my CPU to 4.5GHz. I'm checking if the CM Hyper 212 EVO CPU fan is suitable for that speed.
The maximum overclock height for an I7-6700K depends largely on securing a suitable high-performance chip. As of 12/04/2016, the chances of achieving an overclock with a reasonable 1.4v Vcore are as follows:
I7-6700K
4.9 5%
4.8 21%
4.7 64%
4.6 96%
Generally, you’ll hit safe thermal limits before reaching the overclock before adequate cooling is available, provided your case offers sufficient airflow—typically two 120mm front intake fans or more. When testing, ensure the run time is long enough for temperatures to settle. An 85°C could be a typical benchmark. Under regular loads, you’ll likely see much lower results.

CPU: Intel i7-6700K Quad-Core 4.20GHz
RAM: Kingston 16GB DDR4 2133MHz
GPU: NVIDIA GTX 1060 6GB ASUS ROG Strix
Motherboard: ASUS Prime Z270-A
Storage: Kingston SSDNow V300 240GB
PSU: Cooler Master G650M 650W
It seems it should work fine for the overclock. Just avoid pushing it beyond around 4.7GHz, as temperatures will rise significantly. I performed an OC using RealBench and observed temperatures staying between 85-95°C. After stress testing, the temps dropped to 75-80°C on stock settings—still quite high for a test.
The duration of the stress test was 15 minutes. I’m unsure if I adjusted any fan speeds, as they appear set to default. Should I keep them running longer? I don’t have specific guidance on fan settings for this purpose.

I think it should work for a 4.5GHz overclock. Just avoid pushing it beyond that, since temperatures will rise significantly at around 4.7GHz.
After an OC using RealBench, the temps stayed between 85-95°C. I ran a stress test for 15 minutes and saw the temps drop to 75-80°C on stock settings. That’s quite high for a stress test, right?
How long did the stress test last? Fans usually spike quickly but then settle at lower temps. Are your fans set to adequate RPMs for good cooling?
I changed the BIOS settings, but if you don’t want a noisy fan, adjust it so it runs efficiently without being too loud. A 20-30 minute test might give better results.
