I have a Papst brand (made in germany) 6" PC fan. This runs on 24v. I'm unaware of the flow #s.
I'm wondering if it's a hastle to wire? Where do i get a 24v source?

Not sure if i even need it. Should I just throw it up on Ebay? Not sure what it's worth either.

BTW, sorry about another fan post, I noticed there were 2 already in the top 10 threads :joint:

you just need a small power adaptor (radio shack ect..) but not enough air movement...sell on e-bay worth about 22.00 retail..jack..30cfm 6" 24v....25 watts

wow... what pc fans are those... mine are 3000rpm 140mm ( 5 1/2" ) fans and they push a 150cfm.

Computer fans are useful for air circulation inside a small box but if there is any static pressure like venting through ducting or pulling through a filter they are very inefficient. You can get 50 CFM bathroom fans for $13 at LOWES/HD that will handle some static pressure efficiently but they are somewhat loud and draw about 50 watts.

$10 on eBay for a 24v AC-DC laptop adapter.

Wow. That's a huge axial fan. I found it advertised online. The site claims it pulls 665 CFM (free air) @ 5400 RPM (110VAC with detachable cable). Still impressive, surely, but they wanted $99 for one. I paid $35+S&H for a 6" axial that pulls 235 CFM @ 5400 RPM (110VAC). The cabinet I bought it for is still in the design stage so I'm not entirely sure how well it will cool the 600W HPS. My math says it should be OK as long as the heated air doesn't get sucked back into the cabinet...

As to the original post; finding a 120VAC-to-24VDC adapter is sort of a pain. That laptop adapter may be your best bet but I'm thinking that it'll really run hot if it's powering a fan (which I guess could be OK if you need that heat). Since it's a DC fan, you should be able to "undervolt" it (possibly to 12VDC or even 9VDC); meaning your options as far as adapters go just got a lot wider. I don't think I'd go as low as 5VDC (USB or iPod charging adapter) because it might not start that low. It's not going to hurt the fan to try it, though, so go to town. As long as the adapter is spitting out DC power @ <24 VDC you should be OK.

I seem to recall a method of getting 24VDC out of a desktop computer power supply but that's something you should probably look up on your own.

Well a few weeks ago I wired the 24v fan up to a 12v source. I use it to simply cool off my ballast. I went ahead and ordered a 24v power supply a couple weeks ago but it's not here yet. I ordered on eBay and it's coming from Japan.
Even a 12v, the fan is kinda loud though, I can only imagine how it's going to sound at 24v

Right-o. I can't imagine it'll be any quieter. On the other hand, it might not be drastically louder. Good luck with it!

Crap your old! I remember drooling over the first VIC 20 when they came out. Had to be around 17-18 at the time.
