Catda PWM Mini Cooling Fan Hat Argon Speed Control GPIO Fans with Copper Metal Base Radiator for Raspberry Pi 4 Model B

The Argon mini cooling fan specially designed for Raspberry Pi 4 pure copper metal base radiator pure copper material is the best heat dissipation material it is the perfect combination of cooling fan and radiator Improve the operating speed and service life of the motherboard CPU so you don t have to worry about the inconvenience caused by the motherboard overheating during use In addition the cooling fan also has a switch you can decide whether to use the fan at will you don t need to manually plug and unplug the GPIO interface like a traditional fan Even if the fan is turned off the copper heat sink base can still perform heat dissipation for you Please note In PWN mode the Raspberry Pi mini PWN cooling fan with adjustable speed will only rotate more than 55 degrees by defaultHow to installl Argon Mini FanConnect the Argon Mini Fan to your Raspberry Pi 4Don t power your Raspberry Pi yet 1 Place Silicon Thermal Pad on the CPU of the Raspberry Pi 2 Make sure that the header of the Argon Mini FAN HAT is aligned with physical PINS 1 12 of the Raspberry Pi 3 Check if the HEAT SINK of the Mini FAN is in contact with the Raspberry Pi CPU SET MODE OF THE ARGON MINI FAN1 ON Mini FAN will always turn ON when the Raspberry Pi is powered 2 OFF Turns OFF the Mini FAN3 PWM Sets the Mini FAN into a Pulse Width controllable mode SETTING THE PWM SETTINGS1 In Raspbian open the Terminal App2 Go To the root directory and Open the boot config txt file3 Open and e
