NZXT Kraken X41 CPU Cooler

With the Kraken X41 now out of the box, let's begin our close-up with the head unit. In this version, the circular patterns and NZXT name are now opaque, but this will illuminate with many color options and a few lighting modes. We also see that the Intel mounting hardware comes pre-installed.

While the rest of the round side of the head unit is flat and matches the top in texture, the right side is where all of the connectivity happens. Whether it is the two rubber tubes to allow coolant to flow, or the trio of braided cables, all of the connectivity is kept on this side of the head unit.

Where a few companies had issues keeping theirs from allowing in debris or keeping the plastic protector on at all, NZXT figured it out, and our unit leaves us with nothing to complain about.

Of course, NZXT ships the AIO with a pre-applied patch of thermal paste already on the contact area. While there is nothing wrong with using this, we will be removing it for our testing.

Removing the paste also allows us to show the base in fine detail. It is easy to see that there are milling marks left in the copper, and some will argue that with more surface to contact, heat transfers better. The plate is higher in the middle, and drops almost 1mm from center point to the edge.

With the Kraken X41, there is only room for a pair of fans, so this ten inch version sports a dual four-pin fan lead from the head unit, but no need for the SATA backup power source. There is also the three-pin pump power lead that is nine and a half inches long, and the twenty-four inch long USB 2.0 cable for software control.

While 400mm of tubing technically translates to 15.75 inches, we guess that 15.25" is close enough, as nobody is perfect all the time. Also, even if slightly less than specified in length, there are three inches more in tubing length than the next AIO offers, allowing this AIO to go into more places, more easily.

The aluminium radiator sports a high density, like the X61 did, and keeps to the 22 FPI design. This is also a dual pass design that shoots water in one side, up the radiator, across the top, and then back down through the other side.

The sticker on this end denotes this is the Kraken X41, and also shows that it pulls 12V, and will peak at 7.5 watts while doing so. This also happens to be exactly half of the rating on the X61. We also see that they went with a thicker 37mm radiator, which is thicker than the radiators used on the X40, and the X61.
