Review on Powerful Pack of 4Pcs WINSINN 60mm High-Speed Fan - 12V Brushless 6010 60x10mm by Walter Martin

I am using 12 of these in the fan assembly to supplement my chimney fan. Computer fans are designed to move hot air, so why not. They're working great so far. I suspect they double the flow of warm air from the chimney when the regular fan is running. When the fan is off, they throw out a hair more than the fan itself. The fan also supplies combustion air to the fire. I can turn it off for a slower burn by using these fans just to heat the house while they pull the air out instead of pushing it out like a fan. I love her so far.
