KRAKEN X31 AIO Water Cooling Unit - 120mm - Variable Speed Control

The Worlds First Variable Speed Liquid Cooler

The Kraken X31 takes our Kraken platform to new depths by reimagining our industry-leading platform in a smaller, more affordable package without sacricing performance or the cutting edge technology the Kraken has come to be known for.

Improved mounting hardware and extended tubing make installing the Kraken X31 a breeze to install, while our industry leading SIX year warranty keeps your rig performing reliably at top performance. The Kraken X31’s mix of performance, affordability, and reliability makes this is the perfect time to take the plunge and "Release the Kraken!"

The Kraken X31 is one of the first consumer closed loop coolers with an integrated variable speed pump. The state-of-the-art variable speed pump keeps noise to a minimum during use without sacricing top end pump power.

In addition to the cutting edge hardware, our legacy Kraken Control software has been replaced by our all-new software suite, CAM. NZXT CAM allows you to control your Kraken X31’s fan speeds and other custom cooling settings through its Kraken+ module. CAM also supports multi-Kraken systems natively, allowing you to designate a Kraken as a CPU or GPU cooler and link the fan/pump performance to those specific components.

Excellent AIO cooler, installation a bit

I picked up this cooler while it was on sale and am pleasantly surprised with how well it performs while remaining quiet on my Sandy i7. Over my Arctic Cooler 13, the X31 has knocked about 8


Easy Install

This was my first foray into water cooling and seeing as this one was on offer I jumped in!

Reasonably easy to fit, however you will find the on-line manuals a must, there is minimal included in the box. However it installed fine and runs well. Even with the unit switched to performance mode its very quiet. Processor very rarely comes up above 29c.

All in all its a nice unit.
