Koellichaam/radiator Jonsbo M.2-3 grijs zwart grijs 24,4 mm 73 mm 9,6 mm

The Jonsbo M.2-3 GREY is a compact heatsink designed specifically for M.2 solid-state drives. With a black and grey finish and low-profile dimensions of 24.4mm width, 73mm depth and 9.6mm height, this radiator improves thermal dissipation for NVMe and SATA M.2 modules. The heatsink’s construction reduces operating temperature under sustained workloads, helping maintain steady performance and prolong device life while fitting into tight system layouts.

Advantages

The M.2-3 GREY combines a sleek two-tone appearance with efficient heat conduction through its metallic body. Its slim profile allows installation in compact desktop cases and on many motherboard M.2 slots where clearance is limited. By increasing the surface area in contact with ambient air, the heatsink lowers peak SSD temperatures and supports consistent throughput during heavy read/write activity.

Suitable for

• Cooling consumer NVMe and SATA M.2 SSDs in desktop PCs
• Small form-factor builds where component clearance is constrained
• Systems running sustained disk-intensive tasks such as video editing or large file transfers
• Upgrading thermal management on motherboards without integrated M.2 cooling

Key specifications

• Compatibility: M.2 form factor SSDs (typical M.2 2280 length compatibility when used with matching module placement)
• Material: thermally conductive metal construction for passive heat dissipation
• Finish: black and grey two-tone surface
• Dimensions: 24.4 mm (width) × 73 mm (depth) × 9.6 mm (height)
• Cooling type: passive heatsink / radiator (no active fan)

How to use

Ensure the M.2 SSD and motherboard slot are free of dust and debris before installation. Align the heatsink over the M.2 module so that the contact surface covers the SSD controller and NAND area if possible, then secure it according to the included mounting method or with the appropriate adhesive thermal pad. Recheck clearance with adjacent components such as GPU or expansion cards to confirm the 9.6 mm height fits your build. After installation, monitor SSD temperature during initial operation to verify reduced thermal levels.

Recommendations

For optimal results, pair the heatsink with a quality thermal pad rated for SSD use and ensure airflow in the case is adequate. In compact or densely packed systems, verify mechanical compatibility with motherboard standoffs and nearby components before final installation.
