Review on 🌀 12V Brushless DC Cooling Fan - GDSTIME 80mm x 80mm x 25mm by Gary Haymon

I'm trying to experiment with this 80mm fan that fits perfectly in my 3" radon vent. my house but the ventilation is inherently passive and poorly ventilated. I could spend a few hundred dollars to add a powerful fan, but it's noisy and I wanted to try a simpler approach. I first bought a vent plug to use the air pressure to reduce outlet pressure and help with ventilation. Good for measuring radon levels in my home, the vent cap actually made things worse and is more restrictive than the increase of ventilation. With this fan and solar panel I improved the ventilation cover by putting this fan in a tube and attaching a solar panel on top. See pictures. The solar panel produces up to 17V in bright sunlight. I'll see how it goes, but at this price point of around $25 for the whole upgrade it should have some ventilation.
