Icepc vs SGTKJSJS Heatsink Comparison
Compatible Device
The Icepc heatsink is designed specifically for 50x30mm mSATA SSDs, such as the PM830 and PM851 models. This makes it a precise fit for older or specialized compact drives. In contrast, the SGTKJSJS unit targets the much more common M.2 2280 form factor. It works with standard drives like the Samsung 970 EVO and 960 PRO. You must choose the correct heatsink for your drive size. Using the wrong one will result in poor contact and ineffective cooling. The Icepc fits the smaller mSATA standard, while the SGTKJSJS fits the standard 2280 M.2 NVMe drives found in most modern laptops.
Build Material
Both products rely on pure copper for their heat dissipation properties. The Icepc specification lists its material as pure copper, noting its high thermal conductivity of 401W/mK. This value is significantly higher than aluminum, ensuring efficient heat transfer away from the SSD. The SGTKJSJS heatsink also uses 100% copper that is cut and polished. This shared material choice means both units offer excellent baseline thermal performance. You get the same conductive benefits from either brand, as copper is the superior metal for this application. Neither product uses aluminum or mixed materials in the main heat sink body.
Mounting Method
Installation approaches differ between the two units. The Icepc heatsink uses a high-performance thermal adhesive backing for tool-free installation. You simply peel and stick it to the SSD, which is stable and durable. The SGTKJSJS offers two mounting options: a rubber ring and a high-temperature insulation sticker. This flexibility allows you to secure the heatsink in various laptop configurations. The rubber ring might provide a more mechanical hold, while the sticker offers a simpler adhesive bond. If you prefer a single adhesive solution, the Icepc is straightforward. If you want options for different chassis constraints, the SGTKJSJS provides more versatility.
Dimensions
Physical size is critical for fitting inside your device. The Icepc heatsink measures 40x26x4mm, which is 1.57 inches long, 1.02 inches wide, and 0.16 inches high. It is quite low profile, suitable for tight spaces. The SGTKJSJS heatsink is 3 inches long and 0.87 inches wide. Its height is not explicitly stated in the specs, but it requires a minimum installation height of 1.5mm. The SGTKJSJS is longer to cover the standard 2280 drive length. The Icepc is shorter and wider relative to its length, matching the mSATA footprint. You must measure your available space before purchasing either unit.
Thermal Pads
The SGTKJSJS package includes unique silicone thermal pads in 0.5mm and 1mm thicknesses. These are provided to accommodate uneven surfaces on some SSDs, ensuring full contact with the copper. This is a practical addition for laptops where component height varies. The Icepc data does not mention included thermal pads. It relies on the high-performance thermal adhesive backing for connection. You may need to source separate pads if using the Icepc on an uneven surface. The inclusion of variable thickness pads with the SGTKJSJS simplifies installation for drives with raised components.
Which M.2 SSD Heatsink Fits You
Owner of older 50x30mm mSATA drives
The Icepc heatsink is dimensioned specifically for 50x30mm mSATA SSDs. Its 40x26x4mm size matches the compact footprint of legacy drives like the PM830. The adhesive backing secures the pure copper block without tools. This ensures a direct thermal path for older hardware that lacks standard M.2 2280 form factors.
User with standard 2280 NVMe SSDs
The SGTKJSJS unit is built for standard M.2 2280 SSDs. It includes thermal pads of 0.5mm and 1mm thickness to bridge gaps on uneven surfaces. The design requires a minimum installation height of just 1.5mm, making it ideal for thin laptop chassis where space is tight and standard cooling solutions do not fit.
Seeking maximum thermal conductivity material
Both units use pure copper, which offers 401W/mk thermal conductivity. The Icepc model emphasizes this material property to dissipate heat faster than aluminum. Its broken groove design increases the surface area for air exchange. This construction helps lower SSD temperatures by up to 25°C, depending on your specific environment and workload.

Frequently asked questions
Which heatsink is better for a laptop M.2 2280 drive?
The SGTKJSJS Copper M.2 2280 Laptop Heatsink is the correct choice. It is designed for the standard 2280 form factor used in most modern laptops. The Icepc unit is built for smaller 50x30mm mSATA drives and will not fit a standard M.2 slot. Choose SGTKJSJS for proper compatibility and low-profile cooling.
Does the SGTKJSJS heatsink include a thermal pad?
Yes, the SGTKJSJS model includes a thermal pad. This feature helps transfer heat from the SSD to the copper block efficiently. The Icepc Pure Copper Heatsink does not list a thermal pad in its specifications. If you need a pre-applied interface material, the SGTKJSJS option provides that included in the package.
What are the dimensions of the Icepc mSATA heatsink?
The Icepc heatsink measures 40x26x4mm. In imperial units, this is 1.57 inches in length, 1.02 inches in width, and 0.16 inches in height. It weighs 0.63 ounces. These compact dimensions are tailored specifically for 50x30mm mSATA SSDs, ensuring a snug fit for older or specialized compact storage devices.
Is the SGTKJSJS heatsink suitable for desktop PCs?
It is primarily designed for laptops where space is tight. The SGTKJSJS unit targets low-profile laptop M.2 SSD cooling. While it fits M.2 2280 drives, its small size may offer less thermal mass than larger desktop coolers. For desktops, you might prefer a larger solution, but this works for compact builds too.
How thick is the Icepc copper heatsink?
The Icepc heatsink is 0.16 inches thick, which equals 4mm. This low profile makes it ideal for mSATA drives that require minimal vertical clearance. The thin design ensures it sits flush with the drive without interfering with surrounding components in tight chassis spaces.
What material is used in both heatsinks?
Both products use pure copper for the main heatsink body. Copper offers high thermal conductivity to draw heat away from the SSD. The SGTKJSJS model is described as a copper heatsink, and the Icepc unit is explicitly labeled as pure copper. This material choice helps manage drive temperatures effectively.
Which heatsink is lighter?
The Icepc heatsink is lighter at 0.63 ounces. The SGTKJSJS unit weighs 2.89 ounces. The weight difference reflects the size and material volume of each block. If minimizing added weight is a priority for your build, the Icepc option is the lighter choice.
