As in most thermaltake products, it seems bling factor comes first, performance second and noise fourth (this is not a typo).
The idea of a self-contained water cooling system might be appealing but a stamped out grill at the front, 2cm away from a fan that rotates at a minimum of 1600rpm and a 500L/hour pump is not a good starting point for a silent system.
Light leak is also going to be a concern if you don't care about doubling the energy consumption of your PC with light and uv lamps.
Notice the usual non-realistic specs of the fan & pump :
1600 - 2400 RPM / 10 - 20 dB
500L/h / 10-16dB
AND the mix-up between specs on different parts of the page :
FEATURES : Ultra-low noise fan: 800 ~ 2500 rpm
Thermaltake reliability as usual
Of course you COULD swap the fan, but as the radiator seems quite small, that would probably result in high temperatures which defeats the point of watercooling.
Watercooling of that kind i think is not worth the trouble and noise.
