My H100 keeps my i5 @ 4.8ghz under 70.c.. its not as good as a dedicated system but a lot less hassle and still offers great cooling. The H100 and push and pull fans fitted perfectly into my Fractal arc midi..
An air cooler will do just aswell with the same amount of hassle
I dont really want to spend any more than 80 quid on a case to be honest.What's your budget buddy?
Thats a nice case, puts my cruddy one to shame.
So you've got four fans on the H100 in total?
Is it noisy?
I'd rather go with fans as quiet as poss.....I sometimes leave the box running overnight de\re-muxing.
My H100 was £75 and gives a nice tidy install rather than a big Air cooler hanging off the motherboard. The system I built with an XSPC RS240 kit was only a few .c better.

Slight issue when fitting the H100 to the NZXT Phantom Case if using 200mm fans up top too.
The 120's get in the way of the ram. Dunno what I am going to do yet. Just throwing that out there so someone else doesnt make the mistake
