I would rather use a bigger heat sink than a smaller with fans!. HI-Fi gears do not mix with fans at all!

it all depends on the power "class". You will have to use fans eventually...if you keep on increasing power output.

it will do either 4 pieces of 300 x 250mm, or 2 pieces of 300x 500

not quite that much, but I do have 2 pieces of 2kwatt trafos
but wattage is far over rated with only 2x 38Vac
but with balanced, I think it might be home again
