So ive seen people do this before weather its jerry rigged or done with something like a g12 kraken graphics card cooling with an AIO is possible and is super easy. The only problem is the R9 Nano isnt compatible with the G12 kraken and lets be honest that jerry rigging doesnt look great. What i was thinking about doing was taking the heatsink off and putting an AIO on top of the cpu and having the fan stay in. My only concern is clearence of the fan and AIO. I wanted to get something small and slim like the rosewill aio. Also by removing the heatsink from the gpu there is clearence at the front of the card (near the 8 pin power) where the tubing can go out from. If this is a good idea just leave a comment. If it wont work and could be improved tell me (just no trolling) thanks in advanced!
