Who it fits
Good fit for
This heatsink suits users with M.2 2280 SSDs in laptops, desktops, or PS5 consoles who need a low-profile solution. The 2mm height is critical for devices with limited clearance above the drive slot. If you want to prevent thermal throttling without adding active fans, this passive copper block is a practical choice. It is also good for users who prefer a simple, durable material that does not require power or complex installation.
Who should skip it
You should skip this option if you are installing the heatsink in a desktop tower with ample airflow or a large vertical clearance. The 4mm version is better suited for those setups. Do not buy this if you need an active cooler with a fan for extreme sustained loads. Also, avoid this if your SSD has components that protrude significantly above the chips, as the 2mm pad may not bridge the gap effectively without compression.
Verdict: The JOYJOM heatsink offers a solid passive cooling option for tight spaces using high-conductivity copper. It is a straightforward, spec-driven solution for preventing throttling in constrained environments.
Key specs explained for JOYJOM
Material: Pure Copper
The heatsink uses pure copper instead of aluminum. Copper conducts heat at 401 W/mK, which is significantly faster than aluminum's 237 W/mK. This means the metal pulls heat away from your SSD chip more efficiently. You get better thermal transfer without needing active fans. This is similar to how high-end CPU air coolers use copper heat pipes to move heat from the processor base to the fins quickly.
Dimensions: 70x20x2mm
The physical size is 70mm long, 20mm wide, and only 2mm thick. This low profile is designed specifically for laptops and tight spaces where a larger heatsink would not fit. You must check your available clearance before buying. If you have a desktop or PS5, you might need a 4mm version. This compact size ensures it fits under laptop lids or inside small form factor cases without interference.
Compatible Device: M.2 2280 SSD
This product is sized for standard 2280 M.2 drives, which are the most common length for laptop and desktop NVMe SSDs. It will not fit smaller M.2242 or M.22280 modules. Ensure your drive is the standard 80mm length (2280). This compatibility ensures the heatsink covers the controller and NAND chips properly. It is not a universal fit for all storage formats, so verify your drive size first.
Color: Black
The exterior is black due to a graphite coating over the copper. Graphite helps spread heat across the surface area more evenly. This coating can make the copper look dark, which is normal. If you see small red spots, that is just the bare copper showing through. The graphite layer is thin and does not add significant bulk. It aids in passive heat dissipation by improving surface emissivity.
Design and build details
The heatsink is constructed from pure copper, which offers better thermal conductivity than aluminum alloys. According to the listing, this material choice helps pull heat away from your SSD chip more efficiently. The exterior is coated in graphite, giving the unit a black finish. Small areas of red copper may be visible, which is normal for this design. The surface includes grooves to increase the heat dissipation area. This layout helps lower SSD temperatures by 10 to 30 degrees Celsius in typical environments.
The physical dimensions are 70 by 20 by 2 millimeters. This corresponds to 2.76 inches in length, 0.79 inches in width, and 0.08 inches in height. The unit weighs 1.06 ounces. These compact measurements make it suitable for tight spaces inside laptops or PS5 consoles. You must check your available clearance before installation. The listing notes that a 4mm thickness is available for desktop computers, but this specific model is the 2mm variant.
Installation includes a thermal pad made from silicon grease material. This pad is soft and ductile, allowing it to conform to uneven surfaces on your M.2 SSD. It has low viscosity to avoid damaging warranty labels. The package also provides rubber rings and bandages that can withstand high temperatures. These accessories secure the heatsink firmly to the drive. The design focuses on passive cooling without fans or active controls.
Setup and everyday use guide
Installing this heatsink requires careful measurement before you begin. The listing specifies that you must check the available space around your M.2 slot. You should choose the 2mm thickness for laptops and the 4mm option for desktop computers. This heatsink is strictly designed for M.2 2280 SSDs. It fits standard laptop drives, desktop motherboards, and the PS5 storage expansion slot. Do not attempt to use it with other form factors.
The package includes a 70x20x2mm copper block, a thermal pad, rubber rings, and bandages. You apply the thermal pad to the SSD chip first. The pad is made from silicon grease material. It has low viscosity and good ductility. This allows it to conform to uneven surfaces on the drive. The material is designed to avoid damaging the SSD warranty label during application. You then place the copper heatsink over the pad. Secure the assembly using the included bandages and rubber rings. The bandages can bear high temperatures, which is necessary for long-term stability.
In daily use, the graphite coating gives the unit a black appearance. You might notice small areas of red copper if the coating is thin. This is normal. The groove design on the copper increases the surface area for heat dissipation. The listing claims a cooling effect of 10°C to 30°C. This range varies based on your specific environment. The passive design relies on airflow within your case or console. Ensure your system has adequate ventilation for the heatsink to function as intended.
Before You Buy JOYJOM Heatsink
This is a passive cooling solution for your M.2 drive. You must verify your available space before purchasing. The listing specifies 2mm thickness for laptops and 4mm for desktops. Since this heatsink is pure copper, it conducts heat at 401 W/mK, which is faster than aluminum. The graphite coating helps dissipate that heat. You will need to apply the included thermal pad carefully. Ensure it covers the NAND chips evenly. The rubber rings and bandages help secure it in place. This product fits alongside our other reviews for CPU air coolers and thermal paste. It addresses storage thermal management rather than processor cooling. You should check if your SSD has components that protrude above the controller. The 2mm height is very thin. If your drive is taller, this unit will not fit. Keep the area around the drive clear of other cables. This simple setup requires no fans or power. It relies entirely on conductive transfer and convection.
Check before you buy
- Check if your laptop has 2mm clearance above the M.2 slot.
- Verify your SSD is a standard 2280 form factor.
- Ensure no components on the drive exceed the 2mm height limit.
- Confirm you have the included thermal pad for proper contact.
