The most impressive feature of the H150i Pro is definitely the pre-installed trio of fans. The three low-noise 120mm ML Series magnetic levitation PWM fans might cover more area, but for the better, as they deliver supreme airflow and cooling at the lowest noise level possible of 25dB(A) at full speed, which is quite impressive.

However, if you need a quite surfing time, the Zero RPM mode will serve you right by stopping the fans entirely at lower temperatures, specifically under 40’C. The acrylic pump unit of the H150i Pro draws power from an integrated SATA 12v adapter.

A Micro-B to USB header cable is included to provide full control, especially for precise pumping to maximize performance and minimize noise, according to the temperature needs. 

The acrylic pump is equipped with impressive dynamic multicolor RGB lighting, which can also be addressed via the software control and tuned to your liking.

However, the lighting is limited only to the pump unit, leaving the fans with stock aesthetics, which Corsairs does an excellent job upon.

The base of the acrylic pump is composed of milled copper for efficient cooling. The Modular, tool-free mounting is also a huge plus point. The H150i Pro might not be a suitable choice for compact builds, and neither should be mounted in one.

With tactful planning it can fit in easily in most of the cases, despite the tremendous size, something to be comfortable with if you require a high-end processing build with the i7-8700k, unlocking its full potential in gaming with superb overclocking.

The build quality of the Corsair’s H150i Pro is absolutely impressive and to be trusted, as the manufacturers further secure their position with a 5-year warranty, which makes sure, that there is nothing for you to worry about as you spend top coin on the cooler.

If high-end gaming/processing at overclocked speeds is something you are interested in then this future proof CPU cooler might not seem too expensive, although it is.
