Yep veros too! I dono the cost of a cooler and fan but figured 40 bucks wasn't bad for how clean of an assembly it was, specially being able to mount a holder on with no issues right off the bat.
No, the powersupply for the Led drives also the fan.
"The controller circuit converts any input voltage from 11 to 60 VDC to a fixed lower voltage as required by the fan. The input voltage is derived from the same voltage used to power the LED array."
