I dont want to steer you wrong, maybe the sticks you picked out will fit, maybe they will fit if you use dimm #2 and #4. before listening to me you shoudl search the forusm and see if anyone is running the sticks you picked with the Hyper 212 If you want ram that will fit with nearly any heatsink Id say:
http://www.amazon.co.uk/HyperX-Savage-16-Memory-Module/dp/B00N9PVXJK/ref=sr_1_1?s=computers&ie=UTF8&qid=1448471707&sr=1-1&keywords=16gb+DDR3+1866+Cl9
compared to what you first packed its 1.5v not 1.65v, its 1866mhz not 2400mhz but CAS 9 instead of CAS 10 ...the tighter cas makes up the difference for the slower clock speed if you overclocking the ram this one has more head room, and of coarse its cheaper.
If you were in the US, id say get the cryorig H7 instead of the hyper212, the H7 is better, same price, and fits with most ram but Amazon UK doesnt have it, Im not sure where to get it in the UK I found this for you
https://www.alternate.co.uk/Cryorig/H7/html/product/1174912
but it says available in 51 days, maybe there is some other heatsink slanted like the H7 available in the UK
