H100i PRO RGB is one of the best CPU water coolers in the market designed to cool a CPU like i7 8700k. It has a 240 millimeters radiator that has two advantages that contribute to the cooling effect. First, the radiator cools the liquid in the loop, by doing this, the liquid will not overheat. The second advantage is the surface area that allows more heat to leave your CPU, so it stays cool.

When the heat leaves your CPU, the two Magnetic Levitation fans push them out of the radiator as fast as possible. Besides, these fans can spin up to 2,400 RPM; with this, you’ll get better airflow. What’s more, the Magnetic Levitation technology increases their efficiency and usefulness. As a result, the more CPU usage; the faster the fans to ensure everything remains cool.

Fans can generate vibration, so H100i has mounting pads that prevent vibration. Besides, it has the iCUE software that lets you manage the fan and RGB lights. With this software, you can tune the fan and RGB lights to suit your working environment. If you want to overclock your CPU, this iCUE software has a feature you’ll not find in other CPU coolers.

It’s called the Zero RPM mode; it will stop the fans when your CPU is at a lower temperature after a CPU intensive task like overclocking. During this period, the CPU will heat up, and H100i does its best to keep your CPU cooled. For this reason and others detailed in previous paragraphs, H100i got 10 out of 10 for performance and cooling quality. For design and noise levels we rate it 9 out 10 because the fan will generate noise when working at full speed.
