I just moved from a Q6600 @3.6, but it was a 790i chipset (was on a full watercooled loop). It currently runs on a friend's, same speed, with a Hyper 212+ and runs quite cool.
212+ cost $30, there was also a CoolerMaster mail-in rebate of $10 at the time. It is running just the 1 fan, but you can run 2 in push/pull if you wanted.
You don't need a Corsair Hydro cooler for that CPU and speed unless you want to spend the money for it.
