Who it fits

Key specs explained for this heatsink

Material: Aluminum

Aluminum offers reliable thermal conductivity while remaining lightweight. You benefit from a material that spreads heat away from the source efficiently. This is the standard choice for passive cooling fins. Unlike copper, aluminum is lighter and often more affordable, though it conducts heat slightly slower. For CPU air coolers, you often see aluminum fins paired with copper heat pipes. This heatsink uses pure aluminum for its entire block, making it suitable for components that need steady, passive dissipation rather than extreme peak performance.

Dimensions: 150 x 93x 15 mm

These measurements define the physical footprint and thickness of each heatsink. The 150 mm length and 93 mm width provide a broad base for contact. The 15 mm thickness adds mass, which helps absorb and release heat over time. You must check your case or component clearance to ensure this size fits. Larger dimensions generally mean more surface area for air to cool. When comparing to CPU air coolers, note that this is a compact block, not a large tower cooler with fans.

Base board thickness: 4.3mm

The base is the part that touches the heat source. A 4.3 mm thickness provides substantial material to transfer heat from the component to the fins. This helps prevent hot spots by spreading the thermal energy across the wider fin structure. You benefit from a stable thermal path that reduces the risk of localized overheating. Thinner bases may warp or transfer heat less evenly. This thickness is robust for power transistors and ICs that generate consistent heat loads during operation.

Fins board thickness: 2mm

The fins are the surfaces exposed to the air. A 2 mm thickness balances surface area with airflow resistance. Thicker fins can absorb more heat but may block air movement if packed too tightly. This specific thickness allows for good heat dissipation in passive setups. You should ensure there is adequate space around the fins for air to circulate. In CPU air coolers, fin thickness varies to optimize fan efficiency. Here, the 2 mm design supports steady cooling for components like MOSFETs and voltage regulators.

Weight: 310g (per unit)

Each heatsink weighs 310 grams, indicating a dense and solid build. This mass helps the aluminum absorb thermal energy and release it slowly. You benefit from a stable unit that does not vibrate or shift easily. Heavier heatsinks often perform better in passive applications due to their thermal mass. Compare this to lighter, thinner coolers which may struggle with sustained loads. The weight also suggests durability, as the block is less likely to bend or deform under normal handling or mounting pressures.

Design and build details

According to the listing, the Awxlumv heatsink is constructed from aluminum. This material provides good thermal conductivity while keeping the unit lightweight. You receive two black blocks, each measuring 150 x 93 x 15 mm. The base board thickness is 4.3 mm, and the fins board thickness is 2 mm. This specific geometry maximizes the surface area in contact with cooling air. The design aims to reduce the risk of hardware failure caused by overheating. The large surface area helps dissipate heat passively into the surrounding environment.

The total weight for the two-pack is 10.9 ounces. This weight distribution suggests a sturdy build suitable for mounting on various components. The black finish is standard for aluminum heatsinks and does not affect thermal performance. The listing notes that these units are widely used for computers, power transistors, FETs, ICs, power amplifiers, voltage regulators, MOSFETs, and SCRs. This versatility means you can use them for different electronic needs beyond just CPU cooling.

If you require other sizes or oxidation-resistant models, the listing advises contacting the seller directly. The current design is fixed at these dimensions and material composition. You must ensure your target component fits within the 150 x 93 mm footprint. The 15 mm height provides a balance between surface area and space constraints. This passive design requires adequate airflow around the fins to function effectively.

Setup and everyday use

You install this heatsink by mounting it directly to the component you need to cool. The listing notes a base board thickness of 4.3 mm. This provides a solid surface for thermal interface material. You apply paste to the heat source before pressing the aluminum block against it. The fins board thickness is 2 mm. This creates a large surface area to contact cooling air. The design aims to reduce hardware failure from overheating. You must ensure adequate airflow around the 150 x 93 x 15 mm block. Passive cooling relies on ambient air movement. You should position it where air can flow freely across the fins. This unit is widely used for power transistors, FETs, ICs, and voltage regulators. It also suits MOSFETs and SCRs. You do not need fans or external power for this passive solution. The weight is 310 grams per unit. This adds minimal load to your motherboard or power supply board. You receive two black aluminum blocks. You can use them for dual components or keep one as a spare. If you need different sizes or oxidation finishes, you must contact the seller. The product does not include mounting hardware in the specs. You likely need to source your own screws or clips. Daily use involves monitoring temperatures. The aluminum material spreads heat efficiently. You benefit from reliable thermal conductivity. This setup is static once installed. You do not adjust settings. You simply ensure the component stays within safe thermal limits. The black finish does not affect performance. It is a straightforward, no-frills cooling solution for specific electronic parts.

Before You Buy This Heatsink

This heatsink is a passive component. It relies on case airflow to move heat away from your hardware. You must ensure your computer case has adequate ventilation. Stagnant air will cause temperatures to rise quickly. You need to verify that your target component fits within the 150 x 93 x 15 mm footprint. Check the clearance height in your chassis as well. This unit is not a CPU air cooler with a fan. It is best suited for power transistors, voltage regulators, or MOSFETs. You will need high-quality thermal paste to bridge the gap between the component and the aluminum base. The 4.3 mm base thickness provides a stable mounting surface. Keep the fins clean from dust. Dust accumulation reduces the surface area available for cooling. This product fits into a broader strategy of managing heat in dense builds. It works well alongside active cooling solutions for critical components.

Check before you buy

• Verify your case has strong airflow for passive cooling.
• Confirm the component fits the 150 x 93 x 15 mm size.
• Check chassis clearance for the 15 mm height.
• Ensure you have appropriate thermal paste ready.
• Identify if the target part is a MOSFET or regulator.
