Review on 4Pcs WINSINN 50Mm 5015 Blower Fan 12V 3D Printer Dual Ball Bearing Brushless Cooling Turbo Turbine 2PIN by Todd Nordine

I have installed 2 of these so far, both in 3D printers. They have great air supply, and were a real upgrade to the stock fans that were included. The folks that sell these fans stand behind their products, and were very responsive to an issue with one fan. I will be buying more of these for future projects as they were just the product that I needed. Planning on dual fans on one of the printers soon, but these are so good, may have to dial them back a notch or print really fast! Lol.Update: These fans have been pretty much running 24x7 for a few months now, and no problems whatsoever - great choice for 3D printers. Threw dual fans on one printer and can print overhangs like never before with all the air being pushed by these. Great buy!
