Muffin fan for internal air movement?

[zuren]

Has anyone ever mocked up a 12v muffin fan (aka - computer cooling fan) for moving air inside a camper, campervan, truck cap, etc.?

I have acquired a 200mm Antec Big Boy fan that has a 3 speed switch. I'm trying to figure out if I can use it in my van so I'm looking for some brainstorming ideas from others who have tried.

Thanks for any ideas! Pics would be great!

I was recently shopping for a cabin fan at West Marine. The salesman told me a lot of people are putting those muffin fans in the cabins of their boats.

I've got a 120mm Antec 3 speed fan mounted in the 14" RV style roof vent in my camper van.

As an exhaust fan, on high, it's bloody good. And not loud, but certainly noticeable. On low, I can't hear it. Even on low, it helps a LOT to keep hot air from building up in the fiberglass 2' tall bubble top.

To move air around inside...not so good. I use a 12v oscillating fan for that instead.

I am the muffin fan Nazi.

My roof exhaust.


White fan:
silverstone fm 121 variable speed 4.75 inch fan. Variable speed 33 to 110 cfm and anywhere in between. Less than 0.1 amps to 0.4 amps.

Black fan. Arctic cooling. 53 cfm, 0.15 amps. rotates opposite direction of Silverstone.

When SS fans is on high, turning on black fan makes both quieter, and moves a lot of air.

I have boiled hundred of pots of pasta and cooked thousands of meals 5 feet under these fans in my campervan, The windows don't even fog up. The white roof is not even greasy.

I also have 3 intake fans in a rear window.

In the following pic, one of the black fans have been replaced with another Silverstone.




If I turn these fans on high and turn off my roof exhaust fans, with doors and window closed, the roof fans keep spinning due to airflow.

These are 5 of 10 of my fixed muffin fans. I have some in my footwells, Inside and under my fridge, and one for my computer cabinet..

I've got several more I can plug into my plethora of ciggy outlets and Aim where needed. One, I hang from the roof, about 3 feet down, and it oscillates on it's own, but the pattern isn't always ideal and driving with it hanging is a No no.

Always strange to enter the van sitting in the blazing sun, and it is the same temp, or even cooler than outside.

Great choice of books!

Wilbur Smith books redefine adventure novels, IMO.

RiverGod, The 7th scroll, Warlock and the Quest are thousands of pages I will read again and again.
