Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please
A 300kW engine needs a fan. A 1000W magnetron needs a fan. A 120W CPU needs a fan. Does a 0.06W diode with a big heat sink need a fan?
At less than a watt of heat, that heat sink is plenty to keep the diode cool. Adding a fan would have a negligible impact on the temperature rise, and just make noise. If this did come with a fan, I would remove it immediately :shhh:
Should laptop chargers come with fans? Should home stereos come with fans? How about TVs? Adding a fan to things might in some cases lengthen the life of the product, sure. (or it could clog the device with cat hair?) Hell, the same could be said for TEC cooling all your home appliances. But the added energy consumption and noise just isn't worth it to most consumers. Myself included.
To be fair, at that power they don't really need it. Still, would be nice.
