Key Features
- Purpose-Built 3-Piece Design: Each heat sink is individually sized to match the exact footprint of the Raspberry Pi 4B's CPU, USB 3.0 controller, and RAM chip for maximum thermal contact.
- High-Quality Anodized Aluminum: Lightweight yet highly thermally conductive aluminum alloy with a durable matte black anodized finish that enhances heat radiation.
- Black Finish for Better Emissivity: The dark anodized surface improves infrared heat radiation compared to bare aluminum, offering a slight but measurable cooling advantage.
- Pre-Applied Thermal Adhesive: Each heat sink comes with factory-applied thermal conductive adhesive tape - simply peel the protective backing and press onto the chip for a secure, bubble-free bond.
- Effective Passive Cooling: Reduces CPU throttling during intensive tasks like 4K video playback, compiling code, running servers, or machine learning workloads - no fan noise, no power draw.
- Case & Fan Compatible: Low-profile design fits inside most Raspberry Pi 4B cases and works alongside active cooling fans or GPIO fan hats for maximum thermal performance.
- Tool-Free Installation: No screws, clips, or tools needed - installs in under 60 seconds with a clean peel-and-stick process.
- Sleek Aesthetic: The matte black finish complements the Raspberry Pi 4B's board color and gives your setup a clean, professional look.
