    This AIO was the first one that I have bought for a computer. I am quite familiar with the Corsair brand and their software, iCUE, but the H100i RGB Platinum gave me some significant issues. If you are having constant disconnects/resets of the LEDs, fans, and pump, then make sure you are not running multiple monitoring/sensor software. This caused me frustrations until I determined that running a temperature/fan monitoring software other than just iCUE was causing the H100i to disconnect and reset.

    Built my first gaming PC! I was worried about installing my first water cooler. All I had to do was swap the Intel mount with the ADM mount, and slap it in...thank goodness. Just remember to connect the fans through the cooler instead of the motherboard. They actually have a great instruction book too, unlike most of your parts. No sound, no heat problems, it's an A+ from me

    I used to stay away from liquid cooling systems because I was afraid of them ever failing but after reading so many good reviews of this one, I decided to get it. I used to have a CM Hyper 212 EVO and my CPU temps would jump up to 80-90 degrees during long gaming sessions. With this cooling system, it helped keep my temps down to 60-70 degrees. Liquid cooling is the way to go!
