It's runs very well, trust me. I have the same exact CPU and Heatsink. It's very, very quiet. And it's stable at 34 degrees celcisus.
And by the way, there is a 120mm and a 92mm both in a copper/aluminum combonation, all aluminum, and all copper. Don't cheap out and get the 120mm all copper. By far better heat dissipation on the copper one.
If you can't get the all copper version, get the copper/aluminum. The 120mm copper one will run about $50USD I think. Also, if you're computer isint all that big inside, go for the 92mm.
