I'm using TR Ultra 120EX and it's almost as good as my Swiftech Apogee GT but once fitted you can forget about it, no hassle unlike wc. So definitely I can say TR coolers are by far the best air coolers in the market. Sure there are others like IceAge, Enzotech and Xigmatek to name a few, but none have come close in terms of having a full range of total cooling solution for the pc.

Have achieved 3.87GHz on air with my Q6600 GO hope to experiment more in the coming weeks
