That's the thing though, I want to get a air cooled GPU, something like a 6800XT, and it would blow air UP, so it wouldn't make sense for me to mount the CPU radiator on top, the GPU would just blow hot air right into it, so it would have to me mounted in front of my case. But then I could probably hear it more then if it was mounted on top or the back of the case. I have a HAF 922 (vintage) case and I'd like to leave the 200mm fan on top.Mine are normally very quiet. I have a fan I need to replace that's failing, otherwise, it's not severe. I hardly notice they are even running normally. I do have them in a full tower, and exhausting the waste heat up and out of the chassis. The 140's are quiet compared to the 120's I've had on other AIO coolers
