Today we are taking a look at NZXT’s latest liquid coolers, the Kraken X-3 and Z-3 series. These are more of a refresh rather a total upgrade over last year’s X-2 series, but NZXT has made some notable tweaks. Between the two families there are five different coolers in three sizes, covering the usual 240/280/360mm configurations. Both the X and Z series utilize the same cooling hardware, but NZXT has positioned the Z series as a premium option with a novel aesthetic feature – while the X series has RGB lighting on top of the pump base, the Z series tops its base with a full-fledged (and full color) LCD screen.
