Heatsink/Radiator Jonsbo M.2 GREY Black Grey 1 pc 23.2mm 76.3mm 17.4mm

The Jonsbo M.2 GREY is a compact heatsink designed to improve thermal management for M.2 solid-state drives. Its black and grey finish provides a neutral aesthetic that fits a variety of system builds while the low-profile rectangular shape and measured dimensions (23.2mm × 76.3mm × 17.4mm) allow compatibility with typical M.2 mounting locations and tight spaces on motherboards or add-in card assemblies. The heatsink conducts and dissipates heat away from the SSD controller and flash components to help maintain consistent operating temperatures under load.

Advantages

The heatsink offers passive cooling without moving parts, reducing the risk of mechanical failure and eliminating additional noise. Its solid metal construction increases surface area for heat dissipation, which can reduce thermal throttling during sustained read/write operations. The slim profile helps preserve clearance for adjacent components and fits most M.2 modules that require a low-profile solution. The neutral black and grey colorway supports system integration without visual conflict.

Suitable for

• Cooling M.2 NVMe or SATA SSDs in desktop PCs and compact builds
• System builds where low-profile cooling is required to maintain component clearance
• Upgrades aimed at reducing SSD thermal throttling during heavy workloads

Key specifications

• Material: metal alloy for thermal conduction
• Color: black and grey finish
• Width: 23.2 mm
• Depth / length: 76.3 mm
• Height / thickness: 17.4 mm
• Cooling type: passive heatsink (no fan)

How to use

Remove any protective film from the contact surface, align the heatsink with the M.2 module so the thermal pad contacts the SSD controller and flash memory areas, and press firmly to ensure intimate contact. If the product includes a thermal adhesive or pad, follow the manufacturer’s placement guidance to avoid shifting. Reinstall the M.2 module into its socket or mounting bracket and secure according to your motherboard or device instructions. Verify clearance with adjacent components before final assembly.

Recommendations

For best results, use the heatsink on M.2 SSDs that experience sustained workloads such as large file transfers, gaming, or content creation. Ensure the system has adequate airflow; passive heatsinks perform better when case ventilation removes the heat they dissipate. Check motherboard or device specifications for M.2 slot clearance and confirm that the heatsink height is compatible with any surrounding components or expansion cards.
