2 of this make and type? on power amp heatsink with no other markings other
than moulded numbers on the black housing, so unlikely to indicate temp
etc.
One marked 23 is n/o , to activate fan but seems rather high click over
temp
(soldering iron activation), temp not actually measured yet.
The other is n/c marked 14, overall cutout
Anyone know how to decode these mould marks assuming they do relate to
temp/type or any other ideas?




IME, thermal switches on Power Amps tend to be around the 60 / 90 ballpark.
i.e. 60degrees C switches on the cooling fan, 90 degrees C shuts down the
amp. Its not an exact science.
Whatever you think is appropriate safety vs reliability probably is.

take your pick:
