Bundled Software

Cooler supports CORSAIR iCUE software which can be downloaded from Corsair' website.

CORSAIR iCUE software connects all your CORSAIR iCUE compatible products together in a single interface, giving you complete control over your entire setup.

For testing thermal capability we manually overclocked AMD Ryzen 7 2700X upto 4.1GHz and stressed the CPU using AIDA64 for 10 minutes. To average out we took three readings with 15 minutes of system idle time in between every reading. We compared H115I RGB PLATNUM CPU cooler (CORSAIR iCUE software profile set to ‘Balanced') with few of known AIOs, Air coolers and a custom LC solution.
