Im going to be building my pc in august. The reason why im asking is because I will be cooling my i7-7700k with a Corsair H110i and I just wanted to know if said cooling will suffice or if I should delid my CPU (on top) of having it water cooled. I'm also planning on overclocking it to a minimum of 4,8 GHZ and max of 5,0 GHZ.

Really depends on the temps of your chip, your comfort level delidding, and what you actually plan to replace the paste with etc.

At stock, you can so (as per the link) a near 20'C swing under load, all else being equal - but YMMV.

Personally I'd say, if your OC is stable and a safe temperature - and you're happy with the performance; then there's no "need" to delid.

Also remember, if you do it on a new CPU, you're throwing that warranty out. Delidding will void a warranty.
The chances of a CPU failing within the warranty period (if it works to begin with) are slim..... but the benefit of the warranty is nice.

I'd only really suggest...

I'd only really suggest delidding if you truly 'need' the extra performance and the loss of warranty is worth it to you....
OR on an old CPU that's already out of warranty.

Just my $0.02 though.

the h110 is not a "watter cooling". it a shinny wannabe liquid cooler. like most other AiOs. and honestly, far from best among them.
To delid or not delid is fairly simple question. if you hitting thermal wall before anything else and you must (for whatever reason, even if you just want to) to have higher clocks, you may consider going through deliding.
but frankly, don't waste your money on h110 and 7700K. a decent air cooler for half the price will do the same job and probably at lower noise.
the 7700k is really not worth buying. there are upcoming coffee lake 6 cores and ryzens out there. 4 cores are just not enough today for both gaming and any creativity/productivity work.
