This meccanixity heatsink copper sheet shim review focuses on a simple thermal solution for small components. The product is a 15mm by 15mm copper pad with a 1mm thickness. It includes thermal conductive adhesive tape for direct attachment. You get five sets in the package. The material is pure copper, which offers good heat dissipation for chips, memory modules, or north bridge areas. It withstands temperatures up to 160 degrees. This listing provides a basic, spec-driven look at what these shims offer for desktop computer CPU cooling or other small electronics that lack dedicated cooling fans.
What stands out
- Made of pure copper for effective heat transfer
- Includes thermal conductive adhesive tape for easy mounting
- Dimensions are exactly 15mm x 15mm with 1mm thickness
- Withstands high temperatures up to 160 degrees
- Available in multiple thickness options like 0.5mm and 3mm
Who it fits
Good fit for
You should consider this shim if you need to cool small electronic components like memory modules or chipsets that do not have fans. The adhesive backing makes it easy to attach to tight spaces without complex mounting hardware. It is suitable for desktop computer CPUs or graphic cards where you need a small, passive cooling surface. If you want a simple, durable solution that can handle high temperatures, this copper pad is a practical choice for extending component life.
Who should skip it
Skip this product if you need a high-performance CPU air cooler for a large processor. The 15mm by 15mm surface area is too small for modern high-TDP CPUs. It is not a standalone cooling solution but rather a supplemental heat spreader. If you require adjustable fan speed or liquid cooling, this passive copper shim will not meet your needs. It is also not suitable if you prefer pre-applied thermal pads, as you must handle the adhesive tape application yourself.
Verdict: This is a basic copper shim for small components, not a main CPU cooler. It works well for supplemental cooling on memory or chipsets.
MECCANIXITY Copper Shim Key Specs
Material: Copper
Copper offers high thermal conductivity, moving heat away from hot spots faster than aluminum or plastic. You should use this shim on small chips like northbridge or memory modules that lack dedicated cooling. When comparing to standard CPU air coolers, note that this is a passive heat spreader for localized spots, not a full processor sink.
Dimensions: 15mm x 15mm
The pad is square and compact, fitting tightly around small integrated circuits or VRM components on a motherboard. This size ensures coverage without interfering with surrounding capacitors or traces. For main CPU cooling, this is too small. You would typically use this for auxiliary chips rather than the primary processor core in a desktop setup.
Thickness: 1mm
A one-millimeter profile provides a solid thermal bridge without adding excessive height. This thickness helps fill small gaps between a heat source and a heatsink or chassis. It is thicker than standard thermal pads but thinner than most CPU cooler base plates. Check your available clearance before using it near tall RAM sticks or large VRM heatsinks.
Mounting Type: Thermal Conductive Adhesive Tape
The pad sticks directly to the component surface via an integrated adhesive layer. You peel off the backing and press it on for a permanent bond. This eliminates the need for screws or clips for these small parts. Ensure the surface is clean before application. This method is ideal for static components that do not require frequent removal or adjustment.
Copper Build and Adhesive Design
The listing specifies that these shims are made from pure copper. Copper is chosen for its high thermal conductivity. This material moves heat away from small electronic components faster than aluminum or plastic. The product is designed as a passive heatsink. It does not have fans or moving parts. You attach it directly to the surface of the chip. The adhesive backing is part of the design. It uses thermal conductive glue to bond the copper to the hardware. This eliminates the need for screws or clips. You simply peel the protective layer and press the shim in place. This makes installation quick for tight spaces.
Each shim measures 15mm by 15mm with a thickness of 1mm. The package contains five sets of these pads. The total weight of the package is 0.35 ounces. This light weight means the shims add negligible load to your motherboard. The small footprint allows you to place them on various components. You can use them on northbridge chips, memory modules, or graphics cards. The adhesive ensures the copper stays in contact with the heat source. Over time, the copper surface may darken when exposed to air. This oxidation does not affect the cooling performance. You can sand the surface if you prefer a cleaner look. The design is strictly functional. It focuses on maximizing surface contact for heat transfer. There are no controls or buttons. The only interaction is the physical attachment via the adhesive tape.
Setup and everyday use
Setting up these MECCANIXITY copper shims requires no tools or complex mounting hardware. The package includes five sets of pads, each pre-backed with thermal conductive adhesive tape. You simply peel the protective layer from the sticky backing and press the shim onto your target component. This adhesive mount type allows for direct attachment to small electronic devices, making installation straightforward. The listing notes that the copper material can withstand temperatures up to 160 degrees, which suggests it remains stable during routine operation without degrading the adhesive bond. Once applied, the shim acts as a passive heat spreader. It transfers heat from integrated circuits, graphic cards, or memory modules to the larger copper surface. The 1mm thickness provides a specific gap fill, which may help in systems where components sit slightly below the heatsink base. In daily use, you might notice the copper surface darkening when exposed to air over time. The listing confirms this oxidation does not affect cooling performance. If you prefer a cleaner look, you can lightly sand the surface with fine sandpaper. These shims are compatible with desktop computer CPUs and other small chips lacking dedicated cooling. They are not designed for high-wattage processors that require heavy-duty mechanical pressure. Instead, they suit niche applications where a small, adhesive-mounted copper pad can bridge a thermal gap or absorb excess heat from a nearby hot spot. The lightweight design, weighing only 0.35 ounces per unit, ensures it adds negligible stress to your motherboard or component. You get a simple, spec-driven solution for targeted thermal management.
Before You Buy These Shims
These MECCANIXITY copper shims are passive aids, not standalone coolers. You must pair them with existing cooling solutions like heatsinks or fans. They do not replace a CPU air cooler. Check your component dimensions carefully. The shim is 15mm by 15mm with a 1mm thickness. Ensure your target area, such as a northbridge chip or memory module, fits this footprint. The adhesive backing is permanent once applied. You cannot reposition it without damage. Clean the surface thoroughly before installation. Copper darkens over time when exposed to air. This oxidation does not reduce thermal performance. You can sand the surface if appearance matters. This product fits into a broader system where other components handle the heavy lifting. It complements your main CPU cooler by managing heat from nearby small chips. It is not a substitute for proper airflow. Verify that your motherboard layout allows for this placement. Do not use it on components that require active cooling. It is a simple, low-profile fix for specific hot spots.
Check before you buy
- Confirm your target chip fits within the 15mm x 15mm footprint.
- Verify the 1mm thickness will not interfere with surrounding components.
- Ensure you have a primary cooling solution for the main CPU.
- Clean the application surface to ensure the adhesive bonds properly.
