Well 2 hours into Prime95 torture and I'm at 48c in CPU sensor of motherboard and 50c at the Core sensor at 3.7ghz
I pretty much have the best cable management I can here. Strong intake fan in front 250mm and strong exhaust of 120mm... Coolermaster V8 on CPU...Heatsinks on all four sticks of RAM and my sidepanel is meshed so airflow is indeed good.
All my cables were passed on right side of the case and streamlined, lock-tied and wrapped in UV piping for effect and management
Anyhow I'll stick to 3.7ghz for now since I can keep it running with fairly silent fan operation at 48-50c when gaming and SLI my GTS250
Also I made another post for my HDD setup i'd be glad if you dropped by and helped there
Thanks for your help guys!
