Nice one! I made something similar. The PC coolers in computers dissipate about 75-100w of heat, the temperature delta is about 60 degrees Celsius. I quess that for short time it can dissipate few hundred wats untill the cooler and resistors get too hot. All the best ES5KML

Try tapping the RF and converting it to DC to power the fan. (next project)
