The huge metal blocks that are provided as board coolers on the ASRock Fatal1ty H370 Performance work really well, and the 8-phase VRM design seems totally overbuilt for a board that doesn't really support overclocking due to its chipset, although this design helps with keeping overall temperatures down. There has recently been some misplaced focus on VRM designs, as with this board that uses a doubler to increase the number of available power phases. Like I just said, I feel these concerns are vastly misplaced, especially with a motherboard that costs as little as this one does. Power phase designs might affect extreme overclocking results, but clearly, this H370-based board isn't about overclocking—just meeting the minimum in terms of VRM design would have been sufficient in this particular case. However, this board takes things that extra step with doubled phases, so you can rest assured that this isn't something to worry about with this board (or pretty much any board, to be honest, but that's a subject for another time).
