The design of it that I had in mind was to turn on a small 40x10mm fan to blow on a heatsink when the LED reaches a temperature of around 48C the fans should turn on until it's below that temperature and the fans should turn back off and stay off without any voltage applied.
from what I heard so far I need a MOSFET for it and match a thermistor with it but I can't seem to find the flat kind that I need to put it between the underside of the LED and the backside of the heatsink.
