Features in Detail

🌡️ High Thermal Conductivity

With 73 W/m·K thermal conductivity, this aluminum heatsink efficiently draws heat away from components and dissipates it into the surrounding air—keeping temperatures in check.

📏 Compact 73mm Design

The 73mm length makes it ideal for:

  • M.2 SSDs: Covers controller and NAND chips

  • RAM modules: Fits standard DIMMs

  • VRM cooling: Motherboard voltage regulator modules

  • Raspberry Pi: Cooling for processor and other ICs

  • Graphics card components: Memory chips and VRMs

🏗️ Lightweight Aluminum Construction

Weighing between 10g and 26g, this heatsink adds minimal weight while providing effective passive cooling. No power required—just attach and let physics do the work.

🔧 Easy Installation

Simple adhesive backing allows for tool-free installation. Clean the component surface, peel the protective film, and press firmly to secure.

🎨 Clean, No-RGB Aesthetic

Designed for performance without distracting RGB lighting—perfect for:

  • Professional workstations

  • Server builds

  • Minimalist PC aesthetics

  • Applications where lighting isn't desired
