I5 3570k OC questions

[ehanger]

Is 1.21v a good amount for 4.4GHz on a 3570k? I'm currently running on that doing a P95 small fft test and 30min in so far the max temps are 72,76,77,72. This is in a cheap case with only a single outtake fan (which is attached to the radiator of a corsair h60) and in a hot room with ambient temps north of 30C. Although I set the voltage to 1.21 in bios, cpu-z only displays it as 1.136v even during stress testing, which confuses me. Also by the way, I have intel speedstep enabled. Does everything seem normal?

Specs are

Intel i5 3570k @ 4.4
Corsair h60
ASUS P8Z77 - LK (cheapest asus board with dual pcie 3.0)
Corsair vengeance 8GB DDR3-1600
EVGA GTX 670 (will overclock soon)
Antec one case
Corsair tx750w v2 enthusiast series
Crucial M4 256GB SSD
Win 7 ultimate x64

edit: the case comes with two 120mm fans but the top fan slot was being blocked by the stiff pipes of the H60, and after 30+min of trying to get the damn radiator to fit in this cramped case I didn't feel like messing with anything else.

Further update/report:

Ran unigine heaven benchmark at 1280 x 720 everything else at default, scored 4.8k
Ran it again at 1280 x 1024 and scored 4.1k

max cpu temps ranged from 63-70C across all four cores
gpu temps maxed out at 83C which seems a bit high for non overclocked, could be the case/high ambient temps/stock reference cooler? Another thing is that I haven't changed the fan profile at all.
