NZXT Kraken X40 review

Here we have the fan. You get two of these, 138mm and PWM based as stated. Overall these are pretty good fans, however once the fan reaches full RPM (roughly 800~2000) you will hear it. You can select multiple preset modes ranging from silent to performance in the software, the fans have Liquid State Bearings. 

Here's the cooling block, protected with a plastic cap. All wiring and tubing is pre-fitted for you. At the top you can see an NZXT logo, that is lit with controllable RGB LEDs.

When we flip the CPU cooling block/pump around we see an all copper base, with TIM (thermal grease) already applied for you. Not exactly a mirror / lapped finish though. In the background we see the radiator a little better as well. Fairly easy to mount, some yet not all big-tower chassis have pre-fitted holes and space for 140MM rads/fans. Be sure to check that our before purchasing.

You'll notice that quite a bit of wiring is lead towards the cooling block / pump. On the opposing side the fans feed themselves, one cable needs to go towards your MOBO, One power cable and then that USB connector leads towards your USB port. We'll show and connect all connectors later on in the article.
