Well i live in tucson, so the summers are freakin hot. Sometime i have to turn off my rd becuase it gets so hot it burn to the touch. so i was thinking of install a fan under the detector. heres a drawing on how i will do it. I have a really small fan so im thinking of drilling a hole on the bottom of the rd. and just solder the negative and positive to some source on the radar. Any thoughts.
