Is my cpu cooler good enough to oc to 4 - 4.2Ghz ?

If not which would you recommend.
My system :
6600K
Asus ROG Maximus Hero VIII
CPU cooler:
Cooler Master Hyper T4
Memory Corsair 16GB 2400 LPX
Asus Strix GTX 1070 OC
PSU :
Corsair Proffesional Series 650W (bought in 2012 i think)
Thank you.

I'd be surprised if you can get much above 4.1 without bumping the voltage, but every chip is different. The only way to know what your CPU can handle is to try it. In any case, is your voltage still set to auto? Because the mobo might be jacking up the voltages anwyay. Though obviously not too high because your temps are fine.

The higher you get with an OC the higher the chance of getting an unstable system, so you need more testing. As long as you keep the voltage and temps under control, you won't damage anything, just risk BSODs, etc. Only you can decide whether the extra few hundred mhz of performance...

Read the my CPU fan is only little better than the stoc
Anyway changed the ratio from 35 to 41
How do I know that it took effect?

Are you following an overclocking guide here, or just changing things and hoping for the best?

Overclocking is generally very safe AS LONG AS you follow a good guide and make careful adjustments on settings that you understand. It's a very bad idea to just play around with things in the BIOS and hope for the best.

There are loads of great overclocking guides around. Pick one and follow it carefully, do the stress testing while monitoring your temperatures carefully (especially because your fan is definitely on the weaker side) and you'll be fine. Just don't click and hope!

Yes thank you,,,, I read some guides + youtube....
now Prime95...20min still ok
....changed from ratio 35 to 41....Played on ultra BF1 1440p for 1 hr... temp increased only to 45C .......tempting to do more if it will pass the 1 hr test with Prime95.
Maybe even change the cooler :) soon

Just go with whichever is higher... but you're entirely safe on those temps anyway, so nothing to worry about.

I assume you haven't raised the voltages yet? That's what really has an impact on temps.

OCing 101
Frequency (=speed) you want as high as possible
Voltage you want as low as possible (this is what really impacts power draw and heat).

As you raise the frequency at some point the system will become unstable, you'll get errors, BSODs, lockups, etc. That's because the transistors in the chip can't change state quickly enough to match the CPU frequency. Raising the voltage forces the transistors to change state faster, thus keeping the CPU stable at higher frequencies, but at the cost of additional power draw and heat.

So stress testing at every point, you keep raising the frequency until things get unstable. Then raise voltage. Once stable, you can return to raising frequency again. As you stress test you monitor temps to make sure they stay under control. And set yourself a voltage limit (people will argue anywhere from 1.25 to 1.45... I'd be surprised if you can get much over 1.3-1.35 with your cooling).
