yeh my case is to my bottom right on a small wooden block to raise it up from the carpet to increase air flow and reduce heat. still unsure which cooler to go for. Recently fitted the case out with be quiet fans to see if that reduces the noise, when it didnt i came to the conclusion it was the EVO making the noise under loadI've got two AIO's in my case, one is on the GPU and the other is on the CPU (NZXT) neither emit pump noise. Loudest thing I can hear is the low rumble of my case fans. My case is also down right of me in the desk. That also makes a difference where your case is !
