Corsair one of the most well known brands is preparing to update its venerated and well known H100i all in one liquid CPU cooler with the Corsair H100i Pro, it features a new “Zero RPM fan mode” which would work very similar to many GPUs and would use its integrated fan controller inside the pump block to turn off the fans when the liquid is below a certain temperature, and turn off like many current GPUs and was popularised by Nvidia with their GTX 900 series and later adopted by AMD on the RX 400 series GPUs.

Corsair has said they believe this will help gamers and enthusiasts overcome the biggest downside to liquid cooling, the relative noise level compared to air coolers and get consumers to pick up a H100i Pro.
