Computer Overheating (i think)

[SuperSaiyanSwaggerSSJ4]

so i have had my computer about 7 months now and since i moved house all my games close after about 10 min's of playing, i think this could be overheating. i sometimes get a computer freeze up (screen freezes and it makes that repeated sound of buzzing sort of). a few blue screens. my normal idle heat now for my cpu cores is about 30-35 degrees Celsius and before i moved it was way lower! my specs are -

Windows 7
i5-2570k (oc @ 4.4ghz)
evga gtx 660ti
gigabyte z77-d3h
phanteks ph-tc14pe cpu cooler
8 gig of ram (samsung)
ocz zs 650 watts power supply
adata 128gb ssd
western digital black 1tb

i also only recently got this hard drive, i wouldn't have thought thats the problem because normally hd's either don't work or work.

I reapplied thermal paste but it seems to be even warmer now and my new house is a really stuffy room and it's pretty warm in here 100% of the time.

could it simply be overheating because i am going to get 2 case fans (atm i only have 2 outputs in back and top so i will put input in bottom and side). I have no honest clue what it is though so any thoughts or any other stuff i could explain to you? thanks in advance for any answers

Before you reduce clock speed, keep in mind you need more intake fans than exhaust fans. If you have more exhaust fans you will have negative air pressure in your computer case. This results in poor cooling because the air is less dense and the low pressure attracts dust. If possible you want an intake fan in front, on the side, and on the bottom. Exhaust in the back and top.

Your idle temps are fine, but load temps are what really matter. What are the temps when running Prime95?
