must be like one of them new blade less fan designs they had them for sale at a local shop for moving air about the house, just a centrifugal fan in the base and a big ring on top in which air came out of the perimeter. they suc....err...blew as well. what a pathetic idea THAT was

the porthole from the noob world an here has been opened!! that's how i got in.
I'm not giving up on the idea, just the bushing motor that Castle chose to use for reasons of cost I am sure. Found some 30x30x7mm "ball bearing" fans online for about 8 bucks shipped, so I bought two one to go in the CC Blows and one for my MMM that I discovered after tear down and clean up that the fan no longer works on it...go figure! I will just have to reuse the wires off the other two, no big deal there. Like I said, it's a good concept just a cheap fan. Even with one blade missing after the first heat my motor came back about 20deg. cooler than it normally runs, normally it's 155deg. with the fan 135deg.
