AIO (all in one) liquid cooling units continue to gain popularity due mostly to the cheaper cost to performance ratio, as well as their leak-proof and low maintenance design. If we look back a mere 2 years ago, liquid AIO cooling units were few and far between, and only a few manufacturers offered this type of cooling solution.
Today we find a lot of AIO units flooding the market, and as you may already know, selecting the right one can be a hard choice with so many different styles and types readily available. I am very excited today, because I will be putting three new units on my test bench from NZXT. The NZXT KRAKEN X31, X41 and, Kraken X61 AIO coolers.
These three closed-loop liquid coolers are follow-up products to the Kraken X30 X40 and Kraken X60 that were reviewed last year. The NZXT X31 X41 and X61 have kept their same 120mm, 140mm, & 280mm respective CLC design; however, they now come with some new additions in the form of variable pump speed control, increased radiator thickness, and Cam software. Before I continue, let me tell you a bit about NZXT.
