Review on 🌀 ANVISION 2-Pack 40mm x 10mm DC 5V USB Brushless Cooling Fan with Dual Ball Bearing Design - YDM4010B05 by Kev Mills

This fan has only one speed and spins fast with a high-pitched sound. I use it to cool my cable modem in a cable enclosure. Works great with cooling. Unfortunately, the noise level is high enough to be noticeable at night. For my application I would like a high/low switch so it runs slower and quieter, it should still be good enough to keep the device cool. Now I'm looking for a version that includes speed settings to replace this. .
