52 PI Raspberry Pi 5 Active Cooler with 5mm Copper Heat Pipe and PWM Fan

Specifications

• Compatibility: Raspberry Pi 5 (4GB, 8GB, and 16GB variants)
• Heat Sink Type: Direct-Touch 5mm Pure Copper Heat Pipe with Aluminum Fin Array
• Fan Type: 4-Pin JST PWM Temperature-Controlled Blower/Axial Fan
• Operating Voltage: 5V DC (powered via Pi 5 dedicated fan header)
• Speed Control: Automatic PWM via Raspberry Pi OS kernel thermal management
• Mounting Mechanism: Spring-loaded push pins with rigid brass standoffs
• Thermal Interface: Pre-cut high-conductivity thermal pads included

Minimum hardware 

• Raspberry Pi 5 Board (4GB, 8GB, or 16GB)  to host the cooler and provide power via the dedicated 4-pin PWM fan header
• Official Raspberry Pi 27W USB-C Power Supply  required to deliver sufficient sustained current to both the Pi 5's Broadcom CPU and the active cooling fan under max load without causing under-voltage warnings
• Thermal pads (included)  to provide direct, efficient heat transfer between the CPU/PMIC surface and the copper heat pipe base

Safety Warnings

• Pin Orientation Caution: Connect the fan connector ONLY to the dedicated 4-pin JST PWM fan header located between the GPIO header and the USB-C power port on the Raspberry Pi 5. Forcefully plugging it into the 40-pin GPIO header can damage the fan connector or short board components.
• Power Off First: Always shut down and disconnect main USB-C power from the Raspberry Pi 5 before mounting the cooler or pressing spring-loaded pins into board mounting holes to avoid shorting nearby SMD components.
• Thermal Pad Placement: Ensure protective clear films are peeled off both sides of the thermal pads prior to mounting; leaving protective films on will cause rapid CPU overheating.

Frequently Asked Questions

• Is this 52Pi Active Cooler compatible with the Raspberry Pi 4?
  No, this active cooler is specifically designed for the layout, mounting holes, and dedicated 4-pin JST PWM fan header of the Raspberry Pi 5.
• Can I use this cooler with Raspberry Pi 5 boards in all RAM configurations?
  Yes, it is 100% compatible with the 4GB, 8GB, and 16GB variants of the Raspberry Pi 5.
• Does this cooler fit inside standard Raspberry Pi 5 cases?
  It fits inside cases designed with tall thermal clearance or removable top lids, but it will not fit inside tight, low-profile passive aluminum enclosures.
• Will this cooler interfere with HATs attached to the GPIO header?
  Because of the vertical height of the fin stack and fan wire, standard HATs mounted directly on the GPIO header may require a GPIO header extender or spacer.
• What voltage does the 52Pi Active Cooler fan require?
  The cooling fan operates at 5V DC and draws power directly from the dedicated 4-pin fan header on the Raspberry Pi 5.
  
• How much power or current does the fan draw during operation?
  The PWM fan draws approximately 0.1A to 0.15A at full speed, which is easily delivered by the Raspberry Pi 5 board when using a standard power supply.
  
• Do I need an external power source to run this active cooler?
  No external power supply is needed because power is supplied directly through the onboard 4-pin JST fan header
• Where do I plug the 4-pin cable on the Raspberry Pi 5?
  Plug the 4-pin JST connector into the dedicated fan header located near the top right of the board between the GPIO header and the USB-C power jack.
  
• Can I plug the fan cable into the 40-pin main GPIO header instead?
  No, you must use the dedicated 4-pin JST fan header; plugging it into standard GPIO pins can damage the connector or result in improper PWM control.
  
• Does the cable require manual pin sorting or soldering before installation? No soldering or pin re-arrangement is required as the connector comes pre-wired with standard pinouts matching the Pi 5 header natively.
• Why is the fan not spinning immediately when I turn on my Raspberry Pi 5? The fan is dynamically controlled by PWM and will remain off or spin at low speeds until the CPU core reaches its programmed activation threshold (typically 50°C).
  
• What should I do if my CPU core temperatures remain high under load? Check that the protective plastic film was removed from both sides of the thermal pads and verify that the spring pins are firmly locked in place.
  
• Why is the fan running at maximum speed constantly without slowing down?
  This usually happens if the 4-pin cable is loose or not fully seated into the board header, preventing the PWM control signal from reaching the fan controller.
