NZXT Kraken X73 CPU Cooler
Once free of the confines of the packaging, we took our first look at the head unit and found the cautionary sticker. We simply suggest you follow what the label says, and it is best if you leave this in place until the head unit is installed, as it keeps dust at bay, and also protects against any mishaps that may otherwise scratch the "window."
Under that sticker is a now larger viewable area, which increases the diameter of the ring LEDs behind it. The ring around the reflective plastic is brass that is painted black, and it rotates 360-degrees so that the now hidden NZXT logo inside of it is oriented correctly.
Swivel fittings are a must when it comes to an AIO, in our opinion, and we indeed have a pair of them, which drastically helps with the extra tubing you get. Beyond the fittings, the tube goes over the barbs, it is sleeved, and the plastic/rubber collar is stretched over it and allowed to compress it all.
Near the fittings, we find the connectivity points of the Kraken X73. The larger 10-pin connection supports all of the connectivity for RPM monitoring, power, and the HUE 2 outgoing lead. The smaller connection to the right is for the Micro-USB end of the USB 2.0 control cable.
Removing the plastic cover gives us an unimpeded look at the application of paste from the factory. Not only is the application done well, but again, we find no signs of debris, but it is still coming off of there.
Removing the paste shows us the circular machining marks that are left in the copper cold-plate. What is not as apparent is the slightly convex shape of the plate, highest in the center, to help with proper mounting pressure.
When checking the X53, we were spot on at the 400mm mark, but this time we see the tubes are well over sixteen inches, almost a half-inch longer on the X73 versus the X53. All the same, plenty of distance to make this AIO work in just about any case on the planet.
Helping to push brand identity even without anything running, NZXT presses its logo into the side covers of the radiator. This is done on both sides of the radiator so that any way you install the Kraken X73, it is easily visible.
So that you have a perspective of the thickness of the radiator, we grabbed an image of the end of the header, furthest from the fittings. On it is the product sticker with the model and serial numbers.
Looking through the fins, we find the X73 keeps the high FPI count we expect to see in many AIOs. Plenty of surface area with 22 fins per inch, and with nearly 80 CFM from each fan, we should see some gains in performance.
