[sdiy] Cooling in modular synths

[cheater cheater]

That would mean each cabinet is up to, what, 36W? 45W? Given the
outside area of the cabinet I wouldn't think that it needs cooling,
yeah.

So why do older polysynths need cooling? Was semiconductor technology
just loads more inefficient?

I use mostly power-one or condor PSs, which have substantial aluminum frames that do a good job as heat sinks, as long as there's free convective  air movement around them they seem fine without fans.  imy main DIY has 3 cabinets with 4 or 5 frac racks @ - i haven't measured individual module current draw, but each cabinet has it's own 3amp supply, seems fine.
