I think it is a definite maybe.
Just need to make sure everything works together as needed.
I've seen a few arguments for pulling air up thru low profile or stock heatsinks. The claim is that it's better since the components underneath get a fresh stream of cool air as opposed to being blown on by hot air. Also that blowing down sometimes cycles the same hot air thru the cooler multiple times as opposed to pulling which tends to create a single unified air flow motion. It seems to me that pulling would have less, but cooler air vs pushing would have more, but hotter air; however Im not very familiar personally having never really had a low profile heatsink before and not caring to mess with a stock cooler, so please correct me if I am mistaken.
The theory in my head is that the PSU (CX500M) has a fan that spins up faster when the PSU gets hotter, and when hot air comes in, the PSU will begin to heat up causing the fan to pull more air thru the heatsink. I think it should work similarly to how a CPU controlled fan would, but perhaps with a delayed reaction. At least I hope thats how it will work lol
In terms of power, the AXP-200 has wide gaps between the fins since its designed to be used with a low profile (not pressure optimized) fan. Because of this, the guys at fanlesstech seem to think it could cool a 35W cpu just via convection (http://www.fanlesstech.com/2013/06/exclusive-thermalright-axp-200.html
). Im hoping with a fan at the front of the case and the PSU fan pulling up, that it could do the job for a regular CPU (probably not much room for overclocking but worth testing in increments).
Thanks for the points, please let me know if I am overlooking anything glaring as I am pretty new to building PCs (this will be my 2nd).
