NZXT Kraken X40 AIO CPU Cooler
The round head unit is a dead giveaway of this being an Asetek kit, but unlike most, this head unit from NZXT will illuminate. Both the ring and the NZXT name are fully RGB programmable via the software to match any system, or denote the coolant temperature with a scale from green to red.
The black rubber hoses use a sleeve to keep them attached to the plastic swivel fittings of the head unit. You can also see that right next to the tubing are three braided leads coming out of the head unit.
These leads are to power the head unit with the 3-pin fan connector at the bottom, the USB plug is to allow software to talk to the X40, and the top lead ends with a pair of 4-pin can connections to keep the wiring at the radiator clean, and enables the software to set the fans speeds.
For transportation and sanitary reasons, the head unit is shipped with a clear plastic cover. This will keep anything off the copper surface, and it will help keep dirt out of the thermal paste.
Speaking of the thermal paste, it is pre-applied in a large circle in the middle. This will cover an entire IHS, but since I test all coolers with the same TIM, this textured application needs to be removed.
With the paste out of the way you can definitely see the circular milling marks left behind on the copper plate. There was no dirt in the TIM, and the surface of this base is in really good shape for testing.
I have been mentioning that these new bases are pretty convex, so I grabbed a razor to show you. As you can see the base is very high in the middle, but with the pressure of the hardware kit, it does help this round shape conform to the flatter IHS you are putting it on.
