Corsair H150i PRO review - Product Showcase

Here we have the ML120, 120mm, high static pressure fans. You get three of these, all 120mm and PWM based as stated. The ML series is short for magnetic levitation, at low RPM these fans offer quite a bit of airflow while that low RPM offers low noise. Once they pass ~1000 RPm it's the opposite though. Overall these are good fans, however, once the fans reach high RPM (roughly ~1200) you will hear them. You can select multiple preset modes ranging from silent to performance in the software as well as a zero RPM mode which deactivates the fans up-to a coolant temperature of 40 Degrees C. The default (balanced) configuration keeps things rather silent.

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 360mm rads these days. The unit measures 396mm x 120mm x 27mm.
 

Here we have the cooling block. Inside is the pump as well 1+1 is a patent, ergo this unit is licensed from Asetek. Being an I series (LINK compatible) cooler, there is quite a bit of cabling tied to the unit though. A USB connector, the power cable for fans and a fan PWM cable that leads to the motherboard as well as a SATA power connector to feed it all. 

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.
 

So one cable needs to go towards your motherboard, there is one power cable, one cable for the fans and then that USB connector leads towards your USB port for Corsair's LINK.
