Review on WINSINN 40mm Fan 24V Dual Ball Bearing Brushless 4010 40x10mm 🌀 - High Speed (Pack of 5) - Enhanced Airflow Cooling Solution for Electronics by Brent Shaeffer

I wish I had found this sooner. I used to buy other fans to upgrade my 3D printers. The fans I had were ok but they are nothing compared to these. For starters, these fans came with pin headers attached. This made the installation very quick. Soldering is not required. Second, these fans have a significantly higher CFM rating than the stock fans or upgraded fans I bought for my other printer. I can feel air coming out of the vents on the bottom of my printer. I have not felt any air movement before and no air is coming out of my other printer with another company's "upgraded" fans. Third, I can't believe how quiet these fans are. Since my space is limited, all my printers are in my bedroom. I can easily print to a printer at night with these fans and sleep through the night. Fourth (but perhaps most importantly) I plan to buy two more printers so I will most likely be buying more of these fans. I would consider these fans an "easy" upgrade along with the Micro Swiss All Metal case and hotend. Buy with confidence!
