I'm pretty sure it can handle 4 - 4.2GHz I7 CPU's for daily use (depending on the cpu's output)... for benching and higher look for more exotic cooling devices. But like I said in the other thread that is not the objective of Corsair. It can match a TRUE's performance and even beat it, but even the TRUE stops at 4.0 Ghz with some I7 HT on hotheads. Main thing is you need a well ventilated case to get the max out of it...

Main advantage is ease of installation and bang for the buck.... I don't understand why users expect it to be a top overclocking cooling device... keep price/performance ratio in perspective
