M.2 SSD Cooler Jonsbo M.2-6 Gray — passive heatsink for M.2 NVMe drives, aluminum

Jonsbo M.2-6 Gray is a passive M.2 SSD heatsink engineered for M.2 NVMe drives. Constructed from aluminum, this low-profile cooler attaches directly to the SSD to increase surface area and improve thermal dissipation. It is intended for desktop and compact system builds where additional active cooling is not available or desired, helping to reduce thermal throttling during sustained read/write operations and prolonged workloads.

Advantages

The aluminum construction offers good thermal conductivity while keeping the heatsink lightweight and corrosion-resistant. Its passive design requires no power, moving parts or airflow from a dedicated fan, which simplifies installation and eliminates noise. The low-profile form factor fits most M.2 slots inside cases with limited clearance, and the mounting method ensures direct contact with the SSD controller and NAND for efficient heat transfer.

Suitable for

• Desktop PCs where airflow is moderate and low-noise operation is preferred
• Small form-factor and compact builds with limited internal clearance
• Workstations or gaming rigs performing sustained read/write tasks
• System upgrades where passive cooling is needed without modifying case fans

Key specifications

• Material: aluminum for effective passive heat conduction
• Form factor: low-profile design compatible with M.2 NVMe SSD modules
• Mounting: direct-attach solution designed to contact controller and NAND areas
• Cooling type: passive heatsink — no power or additional components required
• Compatibility: intended for single-sided or double-sided M.2 modules depending on slot clearance

How to use

Remove the M.2 SSD from the motherboard slot, clean the drive surface if necessary, and align the heatsink so it contacts the controller and NAND chips. Secure the heatsink according to the included mounting method, ensuring even pressure for optimal thermal transfer. Reinstall the M.2 module into the motherboard slot and fasten the standoff or screw as usual. Verify that the heatsink does not interfere with adjacent components and that any case clearance is sufficient before closing the system.

Usage recommendations

For best results, use the Jonsbo M.2-6 Gray in systems with at least moderate case airflow and check clearance around neighboring PCIe or M.2 slots; ensure thermal pads (if provided) remain in good condition and replace them if damaged to maintain efficient heat transfer.
