I have a truck camper with a fridge that needs a little help with exhausting hot air that it creates. The camper has a circular grill to the outside, maybe 5" but no extraction fan.
My plan is to place a small computer fan there to draw out the air. Ideally, I need a reliable and quiet computer fan and also some method of controlling the speed, maybe in three stages.
The fan I have currenty draws 3a, which is too much for our solar power use. I would prefer a fan that was around 0.5a or so. Hopefully the controller switch will be an electric rather than resistor style as I don’t want it heating up.
Any ideas for either of those items?
