Tired of your GMKtec NucBox K2 or K4 running hot? The NucBox K2 K4 Ultimate Cooling Top is a 3D-printed replacement top designed to dramatically improve thermal performance across all your core components. Featuring an integrated, quiet 80x10mm USB fan, this high-efficiency cooling top provides an average temperature drop of 15°C, ensuring your mini PC's CPU, RAM, NVMe drives, and other chipsets run smoothly even under heavy workloads.

• Powerful Cooling: Get an average temperature drop of 15°C across your processor, memory, and NVMe drives, preventing thermal throttling and ensuring reliable performance.

• Minimal Noise: The quiet 80x10mm USB fan operates with minimal noise—far less than the stock fan under load—and can be unplugged when not needed.

• Easy Installation: Simply replace the existing top of your NucBox with this cooling top. It securely snaps into place, and the fan is powered by a USB port on the back of the mini PC.

• Sleek, Durable Design: The top features a high-efficiency spiral fan grill that looks great. Made from high-quality 3D-printed plastic, it adds just 12mm to the height of your mini PC.

• Perfect Fit: This cooling top is designed exclusively for the GMKtec NucBox K2 and K4.
