While our detectives are finding a solution to which 240mm fits... here I am wondering how any of you can stand the pump noise from any AIO, and ask you to please post your solutions to removing pump noise entirely. I recognize it's unreasonable to not be able to tolerate the slight high pitch hum at idle, but it seriously grates on my nerves, which is why I've been a proponent of air cooling for so long. I have an H60, which I recognize doesn't have pump speed control, but ffs there has to be something better than that, right?!
