Heatsink/Radiator Jonsbo M.2-3 RED Black Red 24.4mm 73mm 9.6mm

The Jonsbo M.2-3 RED is a compact heatsink designed to improve thermal performance for M.2 solid-state drives. With a black and red color scheme and a low-profile form factor measuring 24.4 mm wide, 73 mm deep and 9.6 mm high, this radiator attaches directly to M.2 SSDs to increase heat dissipation and help maintain sustained read/write performance under heavy loads. The unit is intended for desktop PC builds where space is limited but thermal management remains important.

Advantages

This heatsink increases the surface area available for passive cooling, reducing operating temperatures of compatible M.2 SSDs without adding mechanical noise. The aluminium construction and slim profile enable installation in compact cases and on motherboards with limited clearance. The black-and-red visual style provides a coordinated look for systems with matching color accents while keeping weight and bulk minimal.

Suitable for

• Cooling single M.2 NVMe or SATA SSDs in desktop builds
• Small form factor (SFF) and mini-ITX systems with limited vertical clearance
• High workload scenarios such as gaming, content creation, and large file transfers
• Systems where a low-profile aesthetic with red/black accents is desired

Key specifications

• Dimensions: 24.4 mm (width) × 73 mm (depth) × 9.6 mm (height)
• Material: aluminium alloy heatsink body (passive cooling)
• Color: black with red accents
• Mounting: adhesive thermal pad / clip-style attachment compatible with standard M.2 modules
• Compatibility: designed for single-sided and double-sided M.2 SSDs within standard M.2 length profiles

How to use

Clean the SSD surface to remove dust and oils before applying the thermal interface material. Remove protective film from the thermal pad, align the heatsink with the M.2 module and press firmly to ensure contact across the SSD controller and NAND memory areas. Reinstall the M.2 module into the motherboard or adapter and secure it according to the system manufacturer's instructions. Verify clearance with adjacent components and case panels before finalizing assembly.

Recommendations

Use this heatsink in systems where passive cooling is preferred; ensure there is some airflow in the case to improve passive dissipation. Check motherboard layout and M.2 slot position to confirm sufficient space for the specified 9.6 mm height. For maximum thermal performance, pair with good chassis airflow and avoid stacking other components directly above the M.2 area.
