You are correct about heatsinks. I was referring only to fans. My understanding is that with a heat sink simple passive convection alone is sufficient. Heatsinks designed for air cooling are massive overkill for something as efficient as oil. This would be even more true if the bath was, say, water. I am specifically recalling various descriptions of running oil bath systems where the owners mention that the fans are actually unnecessary.
IMHO the entire point of an oil bath system is to remove noise and moving parts entirely. A mechanical pump and fans outside the box kind of defeats the purpose of the thing. Personally, if I was to build an oil bath system, the object should be to remove the need for a mechanical fan/radiator setup. I wonder if this might be possible by something as simple as, say standing a piece of expanded copper grill, ore even just a bunch of copper pipe inside the unused area of the aquarium several feet into the air.Edited by bombastinator - 12/30/13 at 5:31am
