JOYJOM vs SGTKJSJS Heatsink Specs
Material and finish
Both heatsinks rely on pure copper for thermal conductivity. The JOYJOM model features a graphite coating over the copper surface. This black finish helps with heat radiation while protecting the metal. The SGTKJSJS unit remains bare copper. It is cut and polished but lacks an additional coating layer. Graphite can enhance surface emissivity compared to bare metal. However, both designs use the same base conductive material. The choice here depends on whether you prefer the aesthetic of a coated finish or the traditional look of exposed copper. Both materials are effective for dissipating heat from NVMe drives.
Physical dimensions
Size matters for fitting into tight laptop chassis. The JOYJOM heatsink measures 70 by 20 by 2 millimeters. This translates to roughly 2.76 inches in length and 0.79 inches in width. The SGTKJSJS unit is slightly larger at 3 inches in length and 0.87 inches in width. The JOYJOM model is also thinner at 2mm, which is noted as ideal for laptops. The SGTKJSJS requires a minimum installation height of 1.5mm. Both fit the standard M.2 2280 form factor. If your laptop has very limited clearance, the lower profile of the JOYJOM might offer a better fit without interference.
Included thermal pads
Thermal pads transfer heat from the SSD controller and NAND chips to the heatsink. The JOYJOM package includes one thermal pad made from silicon grease material. It is described as soft and ductile to handle uneven surfaces. The SGTKJSJS option comes with two thermal pads in the box. These pads are available in 0.5mm and 1mm thicknesses. Having two pads allows for better coverage if your SSD has multiple hot spots. The JOYJOM includes only one pad, which might leave parts of the drive uncovered if the chip layout requires more contact area. More pads generally mean better heat transfer coverage.
Mounting hardware
Secure mounting ensures consistent thermal performance. The JOYJOM heatsink uses rubber rings and high-temperature bandages to stay in place. These bandages are designed to withstand heat without degrading. The SGTKJSJS also uses rubber rings and high-temperature insulation stickers. Both methods are suitable for compact laptop spaces where screws are not an option. The SGTKJSJS explicitly mentions insulation stickers, which can be useful for securing the unit against the SSD casing. The JOYJOM uses bandages for a similar purpose. Both solutions are non-invasive and safe for warranty labels, provided you apply them carefully.
Package quantity
The number of units included in the box affects value and versatility. The JOYJOM product includes a single heatsink, one thermal pad, rubber rings, and bandages. The SGTKJSJS package contains two copper heatsinks along with the thermal pads. If you are upgrading multiple drives or need a spare, the two-pack from SGTKJSJS provides more hardware. The JOYJOM is a single-unit solution. This difference is significant if you are equipping a desktop with multiple M.2 slots or a laptop with dual drive bays. You get twice the cooling hardware with the SGTKJSJS option.
Choose the right M.2 heatsink for you
Laptop users needing ultra-thin fit
The JOYJOM heatsink measures just 0.08 inches (2mm) thick. This slim profile fits tight laptop spaces where clearance is limited. The graphite coating aids heat radiation from the pure copper base. It includes a thermal pad and rubber rings for secure mounting. You avoid overheating throttling by keeping your SSD cool in compact enclosures.
Users wanting two units included
The SGTKJSJS package contains two heatsinks for the price of one unit. Each unit is made of 100% pure copper for reliable heat dissipation. It fits standard M.2 2280 SSDs in laptops and desktops. The set includes silicone thermal pads in two thicknesses. You get mounting hardware like rubber rings and insulation stickers for easy installation.
Desktop or PS5 builders
This model is explicitly noted for compatibility with desktop computers and PS5 consoles. The 2mm thickness suits many desktop layouts. The graphite cover protects the copper while improving thermal transfer. It includes bandages and rubber rings for versatile mounting. You ensure safe operating temperatures for your NVMe drive in larger cases.
