I had a response yesterday...had to go to work and lost it. probably a good thing since I ventured off topic. most here on this thread know where the mfg mounts the cooling fans. several have mounted fans above the condenser on top. would anyone want to venture a guess why the mfg might not do that?

Because you would create more heat by pulling air instead of bringing fresh air in to blow through it, I'm guessing. It wouldn't work in a slide you would bring air in from the top vent only.

my thinking was this. by mounting fans directly at the fins, I now have an impediment to natural convection flow IF the fans happen to fail. by mounting at a midway point between upper and lower coils, I do not impede convection flow with the fans off.

I have two fans mounted side by side mid point an two at the top side vent mounted with tie straps to the grill. They exhaust the air which flow upward past the other fans.

This is true you will not trap air when, but you are talking a 3x3 to a impediment natural air flow. Now if you mount the fan above and it comes on it has to blow against the coil and trap the heat. if that makes since to you. So it mounted below to blow over the coil such as a A/C that draws though the coil and exhaust it out. Same principal. When the fan is below you get positive air flow, when the fan is above you get negative air flow.

I have a new Roo with the 6 cubic foot refer and although the fans don't make noise all the time, is there some sort of fan fix to make it quiet? How simple is it or worthwhile to replace stock Dometic Fan?

My thoughts are mount them just above the burner and blow across the entire back.
