Aluminum Heatsink Cooler Cooling Kit for Raspberry Pi 32 Model 3B+ - 2 Piece
This Aluminum Heatsink Cooler Cooling Kit is a passive thermal management solution designed specifically for Raspberry Pi 3B+ single-board computers, featuring two precision-engineered aluminum heatsinks with adhesive thermal pads for optimal heat dissipation. Electronics engineers, IoT developers, and embedded systems professionals use this cooling kit to maintain stable CPU and GPU temperatures during continuous operation, preventing thermal throttling and extending system lifespan. By efficiently transferring heat away from the SoC to the surrounding environment, this heatsink kit solves critical thermal management challenges in resource-constrained computing environments where active cooling solutions are impractical or power-inefficient.
Product Overview
The Aluminum Heatsink Cooler Cooling Kit utilizes passive heat dissipation principles through high-surface-area aluminum construction with superior thermal conductivity. Aluminum's thermal conductivity of approximately 160-240 W/mK makes it an ideal material for extracting heat from the Broadcom BCM2837 processor found in Raspberry Pi 3B+ models. The kit includes two heatsinks: one larger unit for the main SoC and a smaller companion heatsink for the voltage regulator circuit. Pre-applied thermal adhesive pads eliminate the need for thermal paste application, ensuring consistent contact pressure and repeatable thermal performance across multiple installations.
This passive cooling approach operates without moving parts or electrical connections, making it completely silent and eliminating power consumption overhead. The heatsinks are engineered with optimized fin geometry to maximize convective heat transfer when mounted in typical enclosures with modest air circulation. Temperature reduction of 15-25 degrees Celsius under sustained load is achievable, effectively preventing the Raspberry Pi 3B+ from reaching the 80-85°C thermal throttling threshold during CPU-intensive tasks such as video encoding, machine learning inference, or continuous sensor data processing. The compact form factor ensures compatibility with standard Raspberry Pi cases and mounting solutions.

How to Use
Installation of the Aluminum Heatsink Cooler Cooling Kit requires minimal preparation and no specialized tools. First, power off your Raspberry Pi 3B+ and allow it to cool to room temperature for approximately 10-15 minutes. Gently clean the target surfaces on the SoC and voltage regulator using a soft, lint-free cloth to remove any dust or residue that might compromise adhesive contact. The larger heatsink should be applied to the Broadcom BCM2837 processor located at the center of the board, while the smaller heatsink is mounted on the MP2145 voltage regulator chip positioned near the USB ports. Peel the backing from the thermal adhesive pad, align the heatsink perpendicular to the component surface, and apply firm downward pressure for 30 seconds to ensure complete adhesive contact.
After installation, allow the adhesive to cure for a minimum of 2-3 hours before powering on the Raspberry Pi or subjecting it to thermal load. Monitor the system temperature using tools such as vcgencmd measure_temp command or third-party monitoring utilities during the first operational session to verify proper thermal contact and heat dissipation. Under typical ambient conditions of 25-30°C, expect core temperatures to stabilize 15-25°C lower than unheatsink configurations during sustained CPU load. The heatsinks require no maintenance and should not be removed once installed, as repeated adhesive application may reduce thermal coupling efficiency.
Frequently Asked Questions
Will these heatsinks fit inside standard Raspberry Pi cases?
Yes, the heatsink dimensions are specifically engineered to fit within most popular Raspberry Pi 3B+ cases including official cases, Argon One enclosures, and generic plastic housings. The maximum height of the assembled heatsinks is approximately 8-10mm, which accommodates standard case clearances. However, we recommend verifying case specifications before installation if using non-standard or custom enclosures with restricted internal clearance.
Can I use thermal paste instead of the pre-applied adhesive pads?
While technically possible, we do not recommend replacing the pre-applied adhesive pads with thermal paste. The adhesive pads provide consistent contact pressure and repeatable thermal resistance across installations, whereas thermal paste application introduces variables such as paste thickness, spreading, and pump-out that degrade long-term thermal performance. The pre-applied solution is optimized for Raspberry Pi thermal characteristics and ensures warranty coverage.
What temperature reduction should I expect with these heatsinks?
Under sustained CPU load at ambient temperatures of 25-30°C, expect temperature reductions of 15-25°C compared to unheatsink operation. For example, a Raspberry Pi 3B+ without heatsinks typically reaches 65-75°C under full load, while with these heatsinks the same workload results in temperatures of 40-55°C. Actual reduction depends on ambient temperature, case airflow, and workload characteristics. Passive cooling is less effective in high-ambient environments above 35°C.
Are these heatsinks compatible with Raspberry Pi 4 or Raspberry Pi 5?
No, these heatsinks are specifically designed for Raspberry Pi 3B+ and are not compatible with Raspberry Pi 4 or Raspberry Pi 5 models due to different SoC package dimensions and board layout. The Broadcom BCM2711 processor in Pi 4 and BCM2712 in Pi 5 require heatsinks with different thermal interface dimensions. Using incompatible heatsinks may result in poor thermal contact and reduced cooling effectiveness.
Can I remove and reuse these heatsinks on another Raspberry Pi?
Removal of the heatsinks after installation is not recommended as the adhesive pads are designed for permanent mounting. Attempting to remove them may damage the thermal pads and compromise the adhesive bonding capability for reapplication. If you require heatsinks for multiple Raspberry Pi units, purchase separate kits for each board to ensure optimal thermal performance and warranty coverage.
