Features: .High speed silent double fans, with two high speed silent fans up to 10,000 RPM, let the hard disk enjoy cool and refreshing. .Active heat dissipation scheme, supported by high-speed fans, keeps hard disks at a low temperature and enjoys high-speed disk read and write. .Support multi-specification M2 hard disk installation, support single, double-sided chips and 2280, 22110 M2 hard disk installation. .Straight flow air guide trough, straight out air exhaust, quickly take away the heat generated when the M.2 hard disk is reading and writing at high speed. .CNC processing molding, select high-quality raw materials, CNC integrated molding, anodic appearance process, texture fully show. Aluminum alloy cooling parts by the whole aluminum alloy CNC processing molding, using anodic oxidation process can keep bright color for a long time. .Installation tutorial: 1. Remove the label on the hard disk to prevent poor heat dissipation. 2. Attach thermal grease to one side of the hard disk. 3. Slowly insert the hard disk into the heat sink slot (keep the gold finger and the fixed gap outside the slot). 4. Paste thermal grease on the other side (for disks with chips on both sides, use 0.5MM gray spacers on one side) 5. Install the fixing screws and the installation is complete Specifications: .Material: Metal .Product Dimensions: 7.2 x 1.7 x 2.4cm .Product Weight: 150g .Package Dimensions: 13 x 5 x 5cm .Package Weight: 200g .Packing: Carton Box
