Red/White Official Case with Temperature Controlled Fan Case Shell Protection Box Protective Case for Raspberry Pi 5
Feature:
1.Improved Heat Dissipation: With the addition of a self-adhesive 2mmx17mmx4mm heat sink, this product excels at dispersing heat from the processor. This enhanced thermal transfer mechanism effectively prevents any potential overheating problems, guaranteeing optimal performance and reliability.
2.Convenient Accessibility: With a removable cover, users can easily access the fan, cable connectors, and GPIO. This allows for seamless installation of HATs and extensions using brackets and GPIO header extenders (not included), while also facilitating the stacking of multiple cases for expanded functionality.
3.Upgraded Design: This advanced version of the case builds upon the aesthetic appeal of its predecessor, while introducing a plethora of new features for improved usability and efficient heat management. The integrated 2.79 (max) CFM fan, with a fluid dynamic bearing, operates quietly and lasts longer. It can be connected via a four-pin JST connector, enabling temperature-controlled cooling.
4.Efficient Airflow System: The 360-degree slot beneath the cover acts as an intake, drawing in air that passes over the heat sink attached to the BCM2712AP. The expelled air is then directed through the connector openings and ventilation ports on the base, ensuring effective ventilation and heat dissipation.
5.Enhanced Cooling Performance: The elongated case design and secure fitting allow for easy insertion without the need to remove the SD card. The combination of the integrated fan and efficient heat sink design ensures optimal cooling performance.
