very efficient !
Have used these to amplify a 474 mhz , for a medium power output .... the transistor worked well , stable and no fuss !

Excellent fan !
Came attached to a PC Heatsink , by simply and efficiently clipping on .....
I needed this for a special project , and used a little circuit to sense temperature , and then , increase fan speed to cool the heatink .
All at low fan speeds ........
The fan is lovely and quiet and very efficient .....works well !

I like the seed tray , which pulls out for cleaning .........
I will make up a bracket for it as I'm sure the sucker won't last long in the weather ..
