Same problem as you before
When I first installed my 3.0E i pretty much had the same temp problems. 77-85 temps on load with TT Xaser 7.
After spending a more money than I wish to mention I now have a system that is 100% at 38C and 48 loaded.
The few main factors in this temp.
sp-94 (got from newegg)
Tornado 92mm fan (tried the Enermax first but the Tornado is has more capability on hot days in my room)
Fan speed controller. (so you can controll the Tornado)
Artic Silver 5
The most important ....
120MM Delta blowhole .....(sucks dust, hot air and anything else on my computer out) I was able to get 5-6 degrees lower by installing this.
My case temp is usually stable at 28-30C and room temp is about the 70F
