The Platinum series is basically a new variation of the Pro series that came out in January 2018 with a handful of key changes that mainly revolve around the fans and pump head. For starters the pump and block technology used on this series is from CoolIT Systems. The Pro series was based on Asetek technology, so the core components of this new series are very different. Corsair explained to us that when they designed the Pro AIO liquid cooler series that it was done so from a quiet performance standpoint for the workloads by normal desktop users. The new Platinum series takes performance up a notch thanks to fans with higher operating ranges, a new pump head design, and some minor radiator changes. This is a good thing as more cooling performance is always welcomed as AMD and Intel keep adding more cores to desktop processors!

Oh, and you get more RGB. These two new models come with a pair of CORSAIR ML PRO Series RGB magnetic levitation PWM fans that have tuned fan profiles to deliver the right airflow and static pressure at all times. There are also 16 individually addressable RGB LED’s in the pump head to go alone with the four in each fan. That means there is a grand total of 24 RGB LEDs that you can control with Corsair iCUE software.
