I just got mine in today from newegg and installed it. I went from previous temps of 45 idle to 51 load with the volcano 12 with the loud a$$ fan on full blast to 37 idle and 42 load with the same single fan on full blast and 40 idle and 45 load with the fan on low....nice and quiet. What sold me on the product is the fact that I will be able to use it with future 64 AMD's that I will be purchasing and the fact that it was only 2c behind DangerdenRbx watercooling! Here is the article on it. It is heavy but with properly mounting the bracket on the back of my mobo I didnt have any issues with it once standing it up. I am unfortunately only able to fit 1 fan on it in my Lian Li case because of the powersupply being too close....oh well I guess I will just need to get a taller case in the future if I want to add a 2nd unless of course the different mobo's screw holes by the processor are positioned the otherway. I do suggest at least having a case which is 8.5" deep or 216mm. This is what my case it and it comes within a quarter of an inch of the side panel's glass. Either way thumbs way up to thermaltake with this unit.
