The BE Controller didn't come with a power brick (not CrazyGuy's fault).
It is fairly loud. So the fan doesn't adjust? It just going at the same speed (high) constantly.
Do those EVGA PSU come with 8 pcie connectors? I would recommend using all 8 connectors to lower the load on each cable. If you are only using 4 of the connectors, make sure the cables and connection points aren't getting hot. You are drawing about 250 watts through each cable with 4, so make sure they are high quality 16 guage and bump up to 8 if possible, or risk melting the cables or connectors.
