I have a Tuniq Tower 120 on my IP35 PRO on a Q6600 in an Antec 900 case. I have the Q6600 moderately OC'd to 3 Ghz and it is very cool. Currently 34 C on all cores. If your case is big enough, the Tower is excellent. Keep in mind that the really good air cooling rigs are HUGE, but they work well though.
