chalky16 :
I am getting a i5 7500 so is it worth getting an AIO (like the H60) or should I stick with a Hyper 212 or the Cryorig?
Closed loop liquid coolers are seldom any better than their air cooler counter parts.
They're both air coolers in the end, just the all in one water coolers add a radiator to either an intake or exhaust point, which often messes with the case airflow/cooling. In general, unless you need AIO water for a small form factor build, or aesthetics, I suggest sticking to air coolers like the Hyper 212.
Edit: And to add to what others are saying, the stock cooler is fine.
