Review on WINSINN Hydraulic Bearing Brushless 20X6 3Mm by Robert Goodlow

I bought these fans for the Raspberry Pi project. First let me say these fans are SMALL. They move enough air for my purposes and produce a high-pitched rumble. For my application, noise is not an issue but can be disruptive if needed for a quiet environment. It was nice to have a long connection cable. They gave me ways to connect the fan to the power supply. Overall I am satisfied with this purchase.
