I am offering a used cooler from 2020. The cooler is working and was installed on an i9 11900k processor, which is known to be hot by nature. The temperature is good, averaging between 60 to mid-seventies, around 75. I have a kit of 3 Cooler Master Addressable RGB fans that are separate from the cooler. To be honest, there is sound in the pump, but it's working fine. I am selling the cooler for 100, and the fans for 50.
