I have a small 28cm fan assisted roof vent, similar to the link below, fitted to my motorhome.
Link Removed
The vent works well and shifts a lot of air.
The main problem is that the noise level is far too high and becomes a real nuisance.
I would like to reduce the noise level by reducing the speed.
I could do this (I believe) by fitting a series resistance either permanently of withe the possibility of switching it out.
Anyone had any experience with this modification and can offer advice?
