its not that great. When it comes to TT coolers , always remember to get the best performance out of them , you have to lap the base. Their copper quality is great but the base is always ****ty. TT coolers after a nice base lapping turn into cooling monsters. But the Arctic Freezer Pro , with a lapped base is definitely a great great buy for the money.
My personal fav. would always be the TT Big Typhoon though. That cooler is AMAZING. With a lapped base , it works wonders . To an extent of out performing some of the lower end watercooling kits available in the market. Thermalright had some problems with the heatpipes being faulty on their XP120 and XP90 series. Their XP90C is a good offering , again after you lap the base. The bottom line is , if you have a copper base and its not a mirror finish , lap that bast*rd and you will notice a remarkable difference.
