NZXT Kraken x31 AIO Cooler Review

The Introduction:



We all know NZXT: Those crazy guys that made the Alien looking cases, not to mention their fast expansion into the enthusiast PC accessory market. Their diverse product line has taken the industry by storm with new less Alien-looking cases, Performance Fans, Fan Controllers and an awesome line of All In One Liquid Coolers! In conjuction with Asetek, NZXT has led the AIO Liquid Cooling industry into larger 140mm (Kraken x40) and 280mm (Kraken x60) closed loop liquid cooling systems. Now they (and Asetek) have done it again, with a slightly thicker, entry level, 120mm All In One unit. Which should provide better cooling in a smaller package.

So, meet the new NZXT Kraken x31 120mm All In One closed loop Liquid Cooling system! ( Wow, that’s a mouthful! )
