This awxlumv aluminum 100mm heatsink 3 94 x2 72 x1 06 review covers a passive cooling component designed for low-power electronics. It measures 100 x 69 x 27 mm and features black oxide aluminum fins. The unit includes 22 fins to maximize surface area for heat dissipation. You get a single heatsink without additional mounting hardware or fans. It is built for direct contact with components like ICs, FETs, and voltage regulators. The compact form factor allows it to fit into tight spaces where airflow is limited or non-existent. This listing provides the core thermal mass needed for basic heat management tasks.
What stands out
- 22 aluminum fins provide increased surface area for passive heat dissipation.
- Black oxide finish helps protect the aluminum from corrosion and wear.
- Compact dimensions of 100 x 69 x 27 mm fit small enclosures.
- Lightweight design at 8.32 ounces is easy to mount in tight spaces.
Who it fits
Good fit for
This heatsink suits builders working with low-power components such as voltage regulators, MOSFETs, and small ICs. It is ideal for projects where active fans are not possible due to noise or space constraints. Hobbyists building custom power supplies or audio amplifiers will find the 22-fin array sufficient for modest thermal loads. The black oxide finish is also good for cosmetic builds where appearance matters. If you need a simple, passive solution for a specific chip, this size offers a practical fit.
Who should skip it
You should skip this option if you are cooling a high-performance CPU or GPU. The 100mm footprint and lack of a fan mean it cannot handle significant heat output. It is not suitable for modern processors that require active cooling. If you need to cool power transistors with high current draw, this passive unit will likely overheat. Look for a larger heatsink with fan support or heat pipes if your component generates more than a few watts of heat.
Verdict: The Awxlumv heatsink is a basic, passive cooling solution for low-power components. It works well for simple electronics projects but cannot handle high thermal loads.
Key specs explained for heatsink
Material: Aluminium
Aluminum is a lightweight metal that conducts heat well. You get efficient heat transfer without adding heavy weight to your build. This makes it easier to mount in tight spaces. When shopping for CPU air coolers, you will often see aluminum fins paired with copper bases. This heatsink uses pure aluminum, which is standard for passive cooling applications where weight is a concern.
Dimensions: 100 x 69 x 27 mm
These measurements define the physical footprint and thickness of the unit. The 100 mm length and 69 mm width determine if it fits your case or component. The 27 mm height is relatively low compared to large tower coolers. You need to check your clearance before buying. This size suits small form factor builds or specific electronic components rather than high-end desktop processors requiring massive airflow.
Fin: 22 pcs
The heatsink contains twenty-two individual aluminum fins. More fins increase the surface area exposed to air. This allows more heat to dissipate passively. You benefit from better cooling efficiency without needing a fan. When comparing to active CPU coolers, fewer fins might mean lower performance. Here, the count helps manage thermal loads for low-power devices like voltage regulators or small ICs.
Compatible Device: Computer, Power Transistor, FET, IC
This list tells you where the heatsink is designed to attach. It works with computers, power transistors, FETs, and integrated circuits. You should match the component size to the heatsink base. It is not a direct drop-in replacement for standard CPU sockets. Use it for specific electronic parts that generate heat but do not require the high thermal mass of a main processor cooler.
Design and build details
The Awxlumv heatsink uses aluminum for its construction. According to the listing, the material is chosen for its lightweight nature and decent thermal conductivity. You get a passive component that relies on natural air convection. The fins are treated with a black oxide finish. This coating helps with aesthetics and may offer slight corrosion resistance for general use. The unit contains 22 fins arranged in a dense stack. More fins mean more surface area for heat to dissipate into the surrounding air. This design suits components that generate low to moderate heat.
The dimensions are 100 x 69 x 27 mm. You can also see these listed as 3.94 x 2.72 x 1.06 inches. This compact footprint allows it to fit in small cases or on compact motherboards. The height of 27 mm keeps it low, reducing the chance of interference with nearby RAM sticks or other components. The weight is 8.32 ounces. This is light enough to be mounted with standard thermal adhesive or small clips without stressing the PCB.
It is widely used for power transistors, FETs, ICs, and voltage regulators. You should verify that your component fits within the base area. The design is simple with no moving parts. There are no fans or controls. You must ensure your system has airflow to carry the heat away. This heatsink is a passive solution for specific electronic cooling needs.
Setup and everyday use
Setup involves mounting the heatsink directly onto your target component. The unit measures 100 x 69 x 27 mm, which translates to 3.94 by 2.72 by 1.06 inches. You need to ensure your mounting hardware fits the surface area of the device. The base must make full contact with the heat source for proper thermal transfer. Common targets include power transistors, FETs, ICs, and voltage regulators. You will also find it suitable for power amplifiers, MOSFETs, and SCRs. The black oxide finish on the aluminum fins does not change how you install it, but it may help with corrosion resistance over time. There are no fans or active components, so you rely on natural air convection. This means you should position the heatsink so air can flow freely across the 22 fins. Obstructions near the 2.72-inch width or 1.06-inch height can reduce efficiency. The weight is 8.32 ounces, which is light enough for most standard brackets or adhesive mounts. You do not need to manage cables or power connections. Daily use is maintenance-free once installed. The aluminum construction handles steady heat loads without requiring adjustments. If your component generates significant heat, you may need additional airflow in the case or enclosure. The passive design means no noise from moving parts. You simply verify the thermal paste application and secure the mount. The listing notes wide compatibility with various electronic components. You should check the specific thermal requirements of your IC or transistor against the surface area provided by the 22 fins. This ensures the passive cooling is sufficient for your specific application.
Before you buy this heatsink
This component is a passive aluminum heatsink. It does not include a fan. You must provide your own airflow source to move heat away from the chip. Without forced air, the 22 fins will not cool high-power devices effectively. Check your case layout carefully. The unit measures 100 x 69 x 27 mm. Ensure this footprint fits your target component, such as a power transistor or voltage regulator. You also need to verify that your mounting hardware aligns with the base surface. Maintenance is minimal. You only need to dust the fins occasionally to keep thermal transfer efficient. This option suits builders who already have fans or existing airflow. It is not a standalone CPU cooler for gaming PCs. Compare it with active air coolers if you need higher performance. Use it for low-power electronics where noise and moving parts are not desired.
Check before you buy
- Confirm you have a separate fan or airflow source.
- Verify the 100 x 69 x 27 mm size fits your component.
- Check that your mounting hardware matches the heatsink base.
- Ensure the device generates low enough heat for passive cooling.
