flyback cooling

[DaveWM]

I could not wait, the silicone had set up enough to hold the fan so I installed the cage and hooked up a 9v battery.

Its very quiet

when the HV comes up the fan slows down, perhaps the fly is effecting it, like when the neon bulb lights up near the tire.

the air is restricted by the close fitting back, I can put some spacers on the cage that should keep at least some clearance for air to get by, but its not ideal, and there is no real good way to mount it as one side sits next the horz out tube, one side is against the side wall and one side is on the back. I may have worked better if I just mounted it on top and aimed it down but I liked having the fan right up near the fly.
