I have an i7 920 D0 OC'ed to 3.5ghz with a Coolmaster Hyper 212.
I idle at 36-40C and Prime95 up t 69C. The TIM is still curing as I installed it earlier today. I personally don't expect to go over 3.6ghz even after it's cured because it's important to me to have idle low enough that my fan isn't running full blast. I hate noisy systems.
Don't forget that Prime 95 small FFTs is a great CPU stability test and a good temp load test. In gaming or general use it will be less than that. You hit 70C Prime 95 for 30 min, your CPU will be fine for a long time in normal use.
For the OP, you need to read/learn at Frostytech for your HS needs. Sure the TRUE will be a great choice, but you can do the same/cheaper with others.
BTW, reading forum posts and looking at the different forums availible would help you get the right answers.................
