On an NF7S v2, at 2.2 i get 40 idle, 48 load, if i knock it up to 2.5 i get about 50 idle, 58 load. I want to get it higher but the temps just seem to rocket.
I may swap my 201 (which ive only had for about 3 weeks and is a lovely case) for a Lian Li v1000, 120mms fans, should give me decent performance when i put them full up for gaming, then quietness for browsing.
Edit: On my CM i have 2*80mm ins, and 1*80mm exhaust, plus the PSU exhaust.
Oh and i also have an artic cooler on the gfx card.
