Pros: Compact, great cooling, flexible tubes, fairly quiet.
Cons: Specific orientation and setup required, pump make slight noise.
On to specifications, the radiator measures 27mm thick, which is a couple thicker than your average computer case fan measuring 25mm thick. The pump runs at 2800rpm which is near silent. The radiator has a cooling surface of 1385 cm2 which is considerably less than than the other thermaltake units, but only equates to a couple degress c difference with maximum overclocks. Most importantly the tubes measure 326mm or nearly 13 inches, so you should not have any problems no matter your computer setup. The tubes are also very flexible, unlike other all in one watercooling units which have very rigid tubes that arent easy to work with.
In my computer case, which is a silverstone sugo sg05, I could only fit on the the fans because I had clearance issues with the 24pin motherboard connector bending the tubes slightly, so I am only using one fan, and I am still getting amazing temperatures. This will not be a problems for anyone else who is not using a sugo sg05, this is only because my case is so small. But in my opinion, with a radiator this thin, I do not believe that 2 fans benefit much.
On to the bad, you are limited in a lot of ways with this cooler, I contacted thermaltake about horrible pump grinding noise and I was told that the only way to orient the unit for it to be silent and safe is with the tubes coming out of the radiator facing downwards because they dont fill the units all the way up with coolant. They claimed this was because it lowers the risk of the units leaking as some competitors units have leaked before. Also, I was having problems with the pump noise even after that, so I ordered a fan to molex connector so I could hook it up to my power supply, which completely fixed the grinding noise, and the only noise you can hear now is the slight noise of the pump working, which is only audible from ~8 inches away in a computer case with no sound dampening and a lot of mesh, it could be considered silent to many people, especially when most people dont sit with their head right next to their computer. So if you cannot orient the unit with the tubes downward and connect it directly into the psu, you could run into problems with the pump grinding. I cannot say for certain if the pump noise was caused by my motherboards fan connectors, or if the unit is just better being run directly off the power supply.
Overall, after fixing the initial problems I had with the unit, I am very pleased with the unit, and it works perfectly in my sff build. I would recommend this unit to people who want the best cooler in the smallest total package.
