I'm having to drop the blower I picked out: it's just too big.
The fan wheel is 6 1/4" in diameter, and 3 1/8" thick. The problem though, is that the motor sits outside the fan wheel, for a total thickness of 6 3/8", which is also preventing me from centering the fan over the core.
I need a blower that's got the motor inside the fan wheel, like one of those Comair Rotron deals.
If everything goes as expected (i.e. Murphy's law), I won't be able to undervolt it to 5 volts, and the power supply doesn't like a 7 volt load, without a matching 5 volt load to match: my PSU shut down, when I hooked up that blower by itself, in a 7 volt configuration.
So I'll have to add a speed control.
The Surplus Center didn't have anything that matches what I'm looking for.
