Review on Enhanced Cooling Fan and Heatsink Set for Raspberry Pi 4B, GPIO Expansion Board with LED for Raspberry Pi 4B/3B+/3B, DC5V 0.2A - MakerFocus by Charles Butler

Used for my weatherproof portable pi box. At first the fan made a little noise, but after a slight adjustment of the tightening of the mounting screws, everything became normal. The header extender was a bit difficult to push all the way in, but at least don't worry about a bad connection. This fan is my choice as a fan for Pi because of A. No WiFi signal interference (with other fans, they almost all hinder signal strength) B. If the fan is not running, it will not stop passive heat dissipation. physical switch .D. Its low power consumption / high heat dissipation. The aesthetic glow of its lights will make your rig look way cooler than it actually is. My rigs are waterproof portables and floats - how do you like raspberries?
