Pros: -It works
-Pretty quiet, though didn't have a chance to mess with the knob to change speeds, not sure if it doesn't work with a 4-pin connector or not to change speeds, haven't tried in a 3-pin yet.
-Seems I got it just in time, as its now out of stock. (though I wanted to regular Thermaltake Frio Snow Ed., not the OCK version, but cannot find it anywhere, besides outside of the US)
-Matches my computer color scheme, have the Thermaltake Commander MS-I SNow Edition.
-See other thoughts for more information.
-Will update later on when I have time to really try it out.

Cons: It is alot bigger than I thought it would be, but that can't really be counted as a con, as I knew it would be a big cooler, just a little bigger than I thought it would be XD
-Make sure your case can support it, I would reccomend at least 175mm (mine is 170mm and had to push it into my case)
-was hoping the fans could be swapped out for different ones (as I have white LED fans in my case) but doesn't seem they can be swapped without modifying the cooler, but that would be more for looks to me, so thats not a bad thing.

Other Thoughts: It is rated as being 158.4mm tall, and my case can support up to 170mm coolers, however, this barely fit, I had to push and shove it into the the case. To make the specs more acuurate, the motherboard, spacers, and mounts need to be taken into account for the total size. Had to remove my rear exhaust fan as well, but thats not really much of a con, as the other fan on the cooler can act as the rear exhaust. All and All, I like it and would recomend it.
