gigatexal, well done! Tear, you continue to be a champ.
With respect to hot VRMs: If the board is positioned vertically, as inside a case or hanging on a wall, it will dissipate the heat better. If if it's horizontal, a LOT of heat builds up underneath the VRMs. If you can, position the 120mm fans so that they blow across both the top side of the board and the underside.
Looking at your picture, it does appear that you have air passing under the board. OH, sorry, that pic is in Tear's post.
Would you say that the airflow generated over the board by being in a 1U rackmount case is sufficient? Not eager to blow up my board but that's the configuration it's in.
