During an all cloudy day, with low wind, I am still seeing a 4 degree spike on my 5 n 1. Any ideas what I should paint to try and get the chimney effect going? Paint under the cover maybe, where the fan blades are? The stack of the wind cups and the cups themselves? I have no extra heating when the sun is out, like I do when it's cloudy. I can't figure where the heat comes from... Maybe the electronics?
You need a decent enough fan with 24hr power, even the davis spiked when the daytime fars shut down, my homemade
also spiked when the daytime fan shut down, i now have 12v fans in both running 24/7, no more spiking
