NZXT Kraken X31 All-In-One CPU Liquid Cooler
 

NZXT is also moving some of its AIO cooler strategy into the realm of making it smaller and more efficient. The Kraken X31 ticks that checkbox plus a few others, such as software control, variable pump speed, 16 inch tubing leads, and a six year warranty. (Place your own "Release the Kraken," joke here.)
