Neck_Meat...

I like those Antec cases, I have a 300 for my bedroom/server case, and used a 900 for a couple years untill I needed something bigger for my self contained water rig.

[XC] Synthetickiller: Like Neck said, you'll probably lose your core temps when you unlock, but HWMonitor will still show the overall CPU temp on most boards and it's a pretty good judge of where your at.
Usually TMPIN0, or TMPIN1 on most boards. Once you run a stress test it will become pretty obvious...
