Here we have high static pressure fans. You get two of these, both 140mm and PWM based as stated. Overall these are pretty good fans, however, once the fans reach full RPM (roughly ~2,800) you will obviously hear them. The software however never allows them to pass 50% (unless you alter that manually). You can select multiple preset modes ranging from silent to performance in the software though. You can apply a fairly low RPM to them really. The fans have rubber inserts at the screw location, preventing resonating noises.
When we flip it around we see the radiator a little better. Easy to mount, most big-tower chassis have pre-fitted holes and space for 240/280 mm rads these days. The Kraken X63 is a 280 mm model.
Here we have the cooling block. Inside is the pump as well. There is quite a bit of cabling tied to the unit though. USB connector, the power cable and a cable that leads to the motherboard and an RGB cable that can lead towards an NZXT control unit.
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 the performance really is good as you'll find out soon enough. On the opposing side, one cable needs to go towards your motherboard, one power cable and then that USB connector leads towards your USB port for the CAM connection. Notice the screws on the block? That's pretty much a signature for ASETEK, so they are the ODM as they hold a patent on the pump residing in that cooling block.
