Performance
We testedtheH115iRGBProXTatallthreespeedprofiles,and
there’s a significant different between them. This, as we’ve
mentioned, was due to both lower pump and fan speeds. For
instance, the CPU delta T rose from 43°C to 55°C in our Socket
AM4 system between the Extreme and Quiet profiles in our

ten-minutestresstest,althoughthelatterwasstillenoughto

beattheARCTICLiquidFreezerII 240.However,theEKAIO

VERDICT

Monstrous cooling at reasonable noise

levels, although it comes at a price.
