Copper Heatsink Size and Fit
Physical Dimensions
The MECCANIXITY 6x6x4mm Copper Heatsink 5-Pack measures 6mm by 6mm with a height of 4mm. This compact profile suits tight spaces around small chips. In contrast, the MECCANIXITY Heatsink Copper Sheet Shim is larger at 15mm by 15mm but much thinner at 0.5mm. The shim covers more surface area but adds minimal height. You must choose based on the available clearance on your component. The 5-pack offers a traditional finned block shape, while the shim is a flat plate. Select the 5-pack if you need vertical height for airflow. Choose the shim if you need a low-profile solution that spreads heat over a wider area.
Material Composition
Both products use pure copper for their construction. The MECCANIXITY 6x6x4mm Copper Heatsink 5-Pack is made entirely of copper to improve heat dissipation efficiency. Similarly, the MECCANIXITY Heatsink Copper Sheet Shim is crafted from high-quality copper material. Copper is chosen for its excellent thermal conductivity in both cases. This shared material ensures that heat transfers quickly from the component to the heatsink. There is no difference in the base material quality or type between the two items. You get the same thermal benefits from copper regardless of which shape you select. The choice comes down to form factor rather than material performance.
Mounting Method
The MECCANIXITY 6x6x4mm Copper Heatsink 5-Pack comes with ordinary self-adhesive backing. You simply peel off the protective film and stick it to the component. This makes installation straightforward for the block-style heatsink. The MECCANIXITY Heatsink Copper Sheet Shim does not include adhesive. You must use your own adhesive to attach the copper sheet to the hardware. This requires you to source separate mounting tape or glue. The 5-pack offers a more plug-and-play experience right out of the box. The shim requires extra steps for secure attachment. This convenience factor favors the pre-adhered option for quick repairs.
Compatible Devices
The MECCANIXITY 6x6x4mm Copper Heatsink 5-Pack is designed for IC chipset cooling and general chip applications. It targets components that need direct heat sinking. The MECCANIXITY Heatsink Copper Sheet Shim is suitable for chips, notebooks, north and south bridges, and memory modules. It is also used for graphic cards and other small electronic devices without built-in cooling. The shim’s larger surface area makes it versatile for spreading heat across broader components like memory sticks. The 5-pack is more specialized for specific IC chips. Your target component determines which product fits best. Check the size of the heat source before deciding.
Package Quantity
The MECCANIXITY 6x6x4mm Copper Heatsink 5-Pack includes five individual heatsinks in the package. This allows you to cool multiple components or have spares ready. The MECCANIXITY Heatsink Copper Sheet Shim comes in variations of six or twelve pieces. The data shows options for 6 or 12 sheets. This provides a higher count of units for the same type of flat shim. If you need to cool many small areas, the shim pack offers more units. The 5-pack gives you five distinct finned blocks. Consider how many components you need to cool simultaneously. The shim offers more pieces for flat surface applications.
Which one should you buy?
You need compact cooling for small IC chips
The 6x6x4mm dimensions fit tight spaces around small electronic components. The included self-adhesive backing simplifies installation directly onto chipsets. This size offers a practical solution for localized heat dissipation without requiring additional mounting hardware or adhesives.
You require larger surface area for memory modules
The 15mm by 15mm sheet provides a broader contact area for heat transfer. This larger footprint suits memory modules and north bridge chips that need more surface coverage. You must apply your own adhesive, but the increased size aids in spreading heat more effectively.
You want pre-adhesive for quick component repair
This option comes with ordinary self-adhesive already attached, saving you the step of sourcing separate bonding materials. The 6x6mm size is ideal for precise placement on specific hotspots. It is a straightforward choice for stabilizing IC chip temperatures without extra preparation.

Frequently asked questions
Is the 6x6x4mm heatsink good for VRM cooling?
Yes, it is designed for cooling small IC chips and chipsets. The compact 6mm by 6mm base allows you to mount it directly over voltage regulation modules. The 4mm height provides enough surface area for heat dissipation in tight spaces without interfering with nearby components.
What is the thickness of the copper shim?
The MECCANIXITY copper sheet shim is 0.5mm thick. This thin profile makes it ideal for supplementing cooling on memory modules or small chips where standard heatsinks are too bulky. You can place it directly over the component to improve thermal contact.
Does the 5-pack include adhesive backing?
The product description notes that the heatsinks are adhesive-mounted. This means you do not need to buy separate thermal pads or clips. You can peel and stick them directly onto the target component for a secure and simple installation.
Can I use the copper shim for RAM cooling?
Yes, the copper shim is best for cooling small IC chips and memory modules. Its 15mm by 15mm size covers standard DIMM modules effectively. The copper material helps draw heat away from the memory chips to improve stability during intensive tasks.
How does the size of the heatsink compare to the shim?
The heatsink is significantly smaller, measuring 6mm by 6mm with a 4mm height. The shim is larger at 15mm by 15mm but much thinner at 0.5mm. Choose the heatsink for vertical clearance needs and the shim for flat surface coverage.
Is copper better than aluminum for these small parts?
Both products use copper, which has higher thermal conductivity than aluminum. This material choice helps dissipate heat more efficiently from small components like chipsets and memory. You get better heat transfer performance for the same physical footprint compared to aluminum alternatives.
