cpu i7 7700k Overclocking with an air cooler?

[Rcarvalho21]

So I have an i7 7700k CPU, no overclocking just the native 4.2 Ghz clock speed. The cooler is relatively cheap, but it works well with these clock speeds. (hyper 212 evo). Is overclocking safe with this air cooler or would I have to upgrade the cooler to liquid cooling or a more expensive air cooler? I don't have a target for overclocking but this CPU can stabilise at 5.0 Ghz

Air 4.4-4.6

Water 4.6-4.8

Delid & Replace poor TIM application on water 5GHz+

What are the temps?

I get pretty decent temps on the current cooler I have, I haven't stress test but in CPU intensive games like Ghost Recon I'll get like 65 - 75, ish. Varies.

That is going to increase exponentially when you oc. Run Aida64 extreme for a base line then try 4.4GHz and go again. Be aware a common issue with this CPU is the TIM application between the die and IHS being inadequate, you can gain 20 degrees on average and up to 30 by delidding and replacing with liquid metal.

 

EDIT: Obligatory warning that if not delidded properly you can damage the CPU irreparably, do not use a sharp knife you will likely harm it or yourself, if you seriously persue delidding it is plenty safe enough if you purchase a delidding tool.

Can get a mild OC on air as is, but would be good to de-lid if you can as it will decrease temps massively (Get a tool if doing so).
