Review on Noctua NF-A4x20 5V PWM, High-Quality Silent Fan, 4-Pin, 5V Version (40x20mm, Brown) by Nick Gathings

This fan was installed on an nVidia Jetson Nano and it fits perfectly. I received a case for the Jetson Nano that had the appropriate screws to properly install the fan. This fan kit does not come with them as the parts that come with the fan are more likely to be used for mounting to something like a computer case. Anyway, I'm very impressed how quiet the fan runs at full power and doesn't make any annoying noises. the sound of a small high-frequency vacuum cleaner, like most small fans.
