^ This! Looks like these folks will have pretty well anything you need. No need to wait for shipping with online shopping for these kind of parts since you have a bona fide electronics supplier in Saskatoon. I see they have an online presence as well & stock molex connectors. Molex parts will only cost a few bucks, then all you need is any small 12 volt power supply. They should even have the special tool to remove & insert Molex pins. Either cut the connector off, replace with molex or get an adapter like I linked to & cut the molex off your fan. I've recycled a few small power supplies from obsolete equipment that are 12 volt. I'd be surprised if most of us don't have one or two cluttering up a junk drawer. Just need to make sure of the +- wire polarity when you hook it up.

Humidity shouldn't be too much of an issue in your stand & yeah, for $7 not a big deal if the fan bites it after a year or even months. The B&E guys can probably recommend some better moisture resistant connectors for you. Next thing you know, you'll be fabricating bigger & better electronic thingys.

Thanks guys! I'm actually pretty good at soldering and connecting and working with shrink tube and all that. I had to re-wire lights on my logging truck trailer every month or so (they vibrate around and wear off the coating and short out on the frame eventually...always fun finding exactly where the problem is with 110 feet of truck and trailer). The difference is that I just had to cut out a bad section and re-connect, so I knew what I was doing. As long as I know which wires do what, I'll be fine. The only reason this isn't completed yet is because B&E isn't open on the weekends. The guy at OTV Technology where I got the fan told me to go to B&E for a power supply. I didn't want to wait, so I tried about 6 other places, and wasted a bunch of time. I can't believe how hard it is to find a simple 12VDC power supply these days! I'll use the Molex power supply if the price is reasonable, if not, then I'll just buy a power supply with a barrel connector, cut it off and splice in my fan.

You don't have a Can Tire or Wal Merde in Saskatoon? $s to donuts they'll have a 12 volt wall wart. They will probably also have a cheap digital multi-meter for sale. A useful tool for figuring out polarity, i.e. which wires do what. You're not really going to hurt anything with 12 volts DC if you get the polarity wrong, especially with the 9 volt battery scenario. If you reverse the polarity, the fan will either run in reverse or not at all. LEDs as well, they are essentially diodes, so correct polarity, they'll conduct (light up), reverse polarity, they won't. You'd have to apply a very high voltage to cook them in reverse polarity.

Neither Crappy Tire nor Wally's had a 12VDC power supply. So you owe me donuts!!

First thing that comes to mind when looking for 12vdc power supply would be "surplus" section in princess auto. Looks like you have one in Saskatoon
Sorry havent read the rest of the thread or if this will help.

I tried there too. They had one 12VDC, but it was 3A with alligator clips on it.

I'll get to B&E sometime this week.
