3-in-1 Aluminum Heat Sink Set for Raspberry Pi 3
[Aluminium Heat Sink] ❄️ 3-in-1 Aluminum Heat Sink Set for Raspberry Pi 3 High-Quality Aluminum • Self-Adhesive Thermal Tape • Improved Cooling • Easy Installation The 3-in-1 Aluminum Heat Sink Set for Raspberry Pi 3 is a premium cooling accessory designed to improve heat dissipation and maintain stable operating temperatures for Raspberry Pi boards. Manufactured from high-quality aluminum, these heat sinks efficiently transfer heat away from critical components, helping improve performance and extend the life of your Raspberry Pi. The kit includes three aluminum heat sinks of different sizes to cool the processor, Ethernet/LAN controller, and other heat-generating ICs. Each heat sink comes pre-installed with a high-performance thermal adhesive backing, allowing quick and secure installation without the need for additional thermal paste or glue. By reducing operating temperatures, the heat sinks help prevent thermal throttling during continuous operation, making them ideal for overclocking, media centers, home servers, IoT applications, industrial automation, and embedded systems. ⭐ Features Premium-quality aluminum construction Excellent thermal conductivity Self-adhesive thermal tape for easy installation No thermal paste required Lightweight and durable Improves heat dissipation Reduces processor temperature Helps prevent thermal throttling Ideal for continuous operation and overclocking Designed specifically for Raspberry Pi boards Corrosion-resistant aluminum finish Easy peel-and-stick installation 📋 Technical Specifications Product Type: Aluminum Heat Sink Set Compatibility: Raspberry Pi 3 Model A, A+, B, B+ Material: Aluminum Color: Silver Quantity: 3 Heat Sinks Mounting Method: Self-Adhesive Thermal Tape Thermal Interface: Pre-applied Thermal Adhesive Cooling Type: Passive Cooling Weight: Lightweight Installation: Peel-and-Stick 🔧 Applications Suitable for: Raspberry Pi 3 Model B Raspberry Pi 3 Model B+ Raspberry Pi 3 Model A+ Raspberry Pi 3 Model A Raspberry Pi Media Center Home Automation Projects IoT Devices Embedded Systems Robotics Projects Industrial Controllers NAS Servers Retro Gaming Consoles AI Edge Computing Educational Projects DIY Electronics 📦 Package Includes 1 × Large Aluminum Heat Sink (CPU) 1 × Medium Aluminum Heat Sink (LAN/Ethernet Controller) 1 × Small Aluminum Heat Sink (Additional IC / Spare)

Out of stock3.7v – 4V Flower Shape COB led light [ Color – Cool White ]
[COB LED] This Chip on Board COB Led Light is a very small and innovative product, it comes in many different Shapes and Sizes. Its mostly used where the thickness of the product is a very important consideration. This led comes with an Aluminium metal back which acts as a heat-dissipating area for the Led, as these led got hot while running, but for the safety purpose we will recommend you to attach a metallic heat sink with it or paste it on the metal surface. Plate Dimensions ( L x B x H ):- ~74mm X ~22mm X ~2mm. Name of character/shape/letters on COB plate: SHAPE Fan Blade Dimensions of Led Area ( L x B x H ) :- ~62mm X ~18mm X ~1mm. Thickness:- 2mm. Input Voltage:- 3.7v – 4V. Max Input Voltage:- 4v (More than 4v Voltage will completely damage the product ) Aluminum back as a heat sink.
