I don't personally use it, as my girlfriend does not live with me (we're still young) but I have played around with her computer enough to understand it. It is the Rev 2 and it does a moderate job at keeping temps cool. The OP specifically asked for this HSF and I have had some experience with it so I gave my input.
EDIT: I forgot to mention, her Q6600 is OCed to 3.6ghz(1.2ghz OC) on 1.41 or 1.42v and with Prime95, it maxes out on 70-80°C, meaning normal load temps should be about 60-70°C, depending on the cores. This is in a case with a 120mm front intake/120mm rear exhaust and 2 80mm side intake fans and applied with Arctic Silver 5.
In terms of other HSFs, I would opt for something better such as Sun's Core Contact Cooler, Xigmatek's 1283s, CM Hyper 212+, and if you have a decent-sized midtower, the Scythe Mugen 2.
I personally use the Scythe Mugen 2, but it is a HUGE (understatement) HSF. It fits fine in my Antec 902 and keeps my temps very cool without sacrificing performance for it's quietness, waiting on 2 90-100CFM fans to come from Xoxide.com, but they ran out of stock and I'm waiting til they get more.
