jilgri Posted May 22 Share Posted May 22 I received a Corsair H100i Platinum cooler. It has attached two Lenovo Legion fans connected directly to the H100i Platinum unit. About 30 seconds after the computer is powered on, the fans start spinning faster and faster and soon they make huge noise. This happens always, for example: - when the computer fails to boot due to a boot POST error - when entering the BIOS - when the system booted even though the CPU cores temperature average 35 degrees Celsius. The cooler is connected to a SATA cable for power and to the CPU_FAN connector on the motherboard with a single pin/wire for reporting the "speed". This means the H100i Platinum unit is the one controlling the speed of the fans. Is it normal for the fans to spin like this? How can I prevent them from spinning so fast and making a huge noise?
