bobanderson294 Report post Posted May 15, 2019 I would like to install (2) Bergstrom dash fans at headboard in bedroom and wondering if I can utilize the power feed that is going to the 12v headboard lamps? Also, would anyone know of a good source for acquiring 2-speed switches for the fans? Thanks Share this post Link to post Share on other sites
dickandlois Report post Posted May 15, 2019 Bob, Key issue is the fuse size used in the 12 volt circuit for the headboard lights and the current requirements of the fans. The other is the wire gauge and the length of the wire run from the DC power panel. It might also help to install LED bulbs in the light sockets because they draw way less current. You might try Carling for the switch , the other source to look is Waytech they supply a number of items for the transportation industry. Rich. Share this post Link to post Share on other sites
wolfe10 Report post Posted May 15, 2019 Another fan option-- quiet, long life, but more $$. We use them on our boats as well as motorhomes. And at 6.5 watts power consumption, you should have no problem just tapping into 12 VDC wiring for lights. Particularly true if you have changed the lights to LED's. https://www.hellamarine.com/en/products/accessories/fans/turbo-fan.html Share this post Link to post Share on other sites
hermanmullins Report post Posted May 15, 2019 There are a number of 2 speed 12 volt fans on the market that have a 2 speed switchs built in. Just Google 2 speed RV fans. Good luck and stay cool. Herman Share this post Link to post Share on other sites

They are both 7" / 2-speed Bergstroms (same fans as my two factory installed dash fans). Share this post Link to post Share on other sites

Herman Thanks Herman, The Bergstrom fans I have are two speed, however they do not come with a switch so I purchased a couple of 3-position switches at local Auto parts supplier.

I find my dash fans to be quite noisey. Well you already have them, try them, after you get tired of the noise I would look at the ones Brett linked to.

richard5933 Report post Posted May 15, 2019 This is what we use in the bedroom. Quiet and doesn't use very much current. Plug into any USB outlet. Moves a surprising amount of air. https://www.amazon.com/gp/product/B077SDZL88/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Share this post Link to post Share on other sites

I have often thought of installing a pair but I figured they would dry out my contact lenses Share this post Link to post Share on other sites
bobanderson294 Report post Posted May 16, 2019 Thanks, you make a good point about the noise. I may just keep the dash fans for spares and go with the one suggested. Share this post Link to post Share on other sites
