Even with the fan the thermal resistance is quite high with just the TO-3 package...

Ugghhh... makers.
So bad, instead of screaming "good grief," C.B. can only facepalm.

Well, technically speaking, wood does have better thermal conduction than air.

As to how much difference this will make instead of running the transistor just in open-air is a whole another topic.

Oh, and hope that's a genuine 3055 BJT and not a cheapo knockoff China one with a fractional die area.
