RX 580 VRM cooling

[FawnPoem]

This is probably a dumb question but if I where to attach an AIO to my 580, could I get away with attaching a fan above the VRM or would I have to apply heatsinks on the mosfets?

Well you buy aftermarket heatsinks with thermal pads and some decent airflow into case would help and how you stick them as well.
Thats how would i do, but wait for other answers.
