I have given up on NZXT coolers due to their planned obsolescence. They dropped software support for their older coolers after as little as a year after release.
For example, they refused to fix bugs with the kraken control software, thus it slowly became unstable with the many windows updates, and eventually got to a point where the fan speed control no longer worked properly. The fans only ran at 2 speeds (basically around 1500RPM and 2000RPM, both have the fan being insanely loud.

Early versions of the CAM software did not have this issue, and supported the X40, but those beta versions were also unstable and if they crached, the the fan speed would be stuck at whatever the last fan speed was, thus if it freezed while the system is idle, the fan speed does not increase while you are gaming.
They eventually fixed many of the stability issues, but they also removed support for the X40, thus the software would no longer detect it, thus you are stuck with the no longer properly compatible kraken control software.
In bring that to their attention, all they could say is to buy one of their other overpriced coolers.
So I took their advice and ditched the X40 and went with a NH-D15, and replaced the NZXT fan with a 140mm noctua fan for the exhaust vent.
Overall, my system went from this: https://i.imgur.com/gmyiEFH.jpg, to this : https://i.imgur.com/yIfWGjC.jpg (taken while installing the replacement cooler).
I will eventually upgrade again when I find a good 240mm or 280mm radiator to mount to the top of the case, but given NZXT's software support, my next cooler will not be from them.
