quiet and small, in fact unless i felt the side of the pump motor case, i could not tell if it was running ( aside from the small air bubbles which eventually bled out from the pump running ), the 2 supplied motor plastic / rubber mounts effectively make it dead quite. It hooks up to your CPU fan header on the motherboard. I set mine up with the 1/2" compression fittings in lieu of the stock 1/2" barbed fittings.
Works Great!

I purchased one for each of my loops. It keeps my 3870X2 below 33 C and my OC''ed E8500 below 26 C @ idle. (Using 1 DD Black Ice GTX 360 for each) This pump is very quiet, I can''t hear it over my fans when they are turned all the way down. The included brackets makes it easy to mount it just about anywhere.
AMAZING

This pump is amazing...moves the liquid at a fast rate and it is very quiet. Just like everybody said it is a great pump and its really small so it fits just about anywhere...If you want a good pump buy this one, its worth the money.
Holy Crap!

I bought this pump to replace the crappy pump on the Thermaltake Bigwater SE. WOW, what a pump. It moves water at an awesome flow rate and makes hardly ANY noise! To make things better it can even have the impeller RPMs monitored from your motherboard. Thermaltake should consider contracting Danger Den to do their pumps!
Great Pump

I bought this for a loop to cool the CPU only, and it works excellent in this regard. It pushes a LOT of coolant for as quiet as it is, and thanks to the rubber/plastic mounting brackets, you can mount this virtually anywhere and in any position.
