JEYI M.2 NVMe SSD Heatsink

Passive Cooling and Performance

JEYI produces a range of passive heatsinks for M.2 NVMe and NGFF SSDs. By drawing heat away from the drive and dissipating it into the surrounding air, these heatsinks help prevent thermal throttling, a phenomenon where a hot SSD reduces its speed to protect itself . The cooling performance is substantial, with some JEYI models offering a temperature reduction of 10°C to 30°C or even up to 40°C depending on the model and environmental conditions .

Form Factor and Compatibility

JEYI heatsinks are predominantly designed for the standard M.2 2280 form factor (22mm wide, 80mm long) . They are compatible with a wide range of high-performance drives, including the Samsung 980 Pro, 970 Pro, Western Digital SN850, and Corsair MP600 . However, compatibility with double-sided SSDs is not guaranteed and should be confirmed before purchase .

Material and Design Variations

The product line offers significant variety in materials and design:

• Copper Variants (e.g., Finscold Q150): Feature a heavy copper heatsink with 36 internal copper fins. Copper’s high thermal conductivity of 401 W/(m·K) makes it an excellent choice for cooling high-heat drives .

• Aluminum Alloy Variants: Many models use a magnesium-aluminum alloy with an anodized finish to improve durability and corrosion resistance .

• Low-Profile Options (e.g., DazzCold-006): A slim heatsink with a 6-10.5mm height, specifically designed for space-constrained builds like PS5, mATX, and MiniATX motherboards .

• Active Cooling Models: A few JEYI models integrate a 3-pin silent turbo fan, providing active airflow for even greater cooling efficiency .

Physical Dimensions and Installation

Physical dimensions vary, with models like the DazzCold-006 measuring 73.5 x 23.1 x 10.5mm, while the fan-equipped model is 77 x 24 x 40mm . Installation requires mounting thermal pads between the heatsink and the SSD to ensure proper contact and is generally straightforward, using screws or clips .
