NZXT Kraken X73 RGB AIO CPU Cooler Review

We covered the unboxing of the original Kraken X73 in detail during our initial review, since this new X73 RGB is almost identical, we will skip the unboxing this time around for a more streamlined review. If you want to check out the original unboxing and first look, head over to our original review HERE.

However, it is worthwhile checking out these new Aer RGB 2 fans and comparing them against the original Aer P 120mm units that came with the regular X-3 and Z-3 coolers.

I was expecting the Aer RGB 2 fans to look very similar to the Aer P, possibly with just the Colour Trim rings exchanged for RGB modules. That is not quite the case, the Aer RGB 2 fans have a much more chunky feel to them and are probably not as nice looking as the Aer P fans when the RGB lighting isn’t active.

Aer RGB 2 fans have nine blades compared with seven in the Aer P and the blade angle of the Aer RGB fans is steeper than its Aer P sibling. The four screw mounting points feature anti-vibration rubbers to reduce noise, Aer RGB 2 are also equipped with a Fluid Dynamic Bearing and have a 60,000 hour/6 year lifespan.

Connectivity consists of a standard 4-pin PWM plug to connect directly to motherboard headers as well as a proprietary 4-pin RGB connection that links fans together to be connected to the RGB cable connection on the Kraken X73 AIO CPU block.

When the RGB is illuminated, these new Aer RGB 2 fans look great. There are no obvious signs of LED hotspots or light bleeding out from around the sides of the diffusers and the RGB lighting effects are bright and vivid, good job NZXT.
