Who it fits
Good fit for
You should consider this heatsink if you need passive cooling for small components like power ICs, LED drivers, or NEMA 17 stepper motors. The 25mm footprint is ideal for cramped enclosures where larger coolers do not fit. It is also a good match for the ASUS ROG Ally, as noted in the specifications. If you are building a low-noise device or need to cool multiple small chips, the six-pack value and adhesive backing make setup straightforward.
Who should skip it
Skip this product if you require active cooling for high-heat processors. This heatsink relies solely on passive aluminum fins and has no fan or liquid cooling loop. It is designed for low-power components, not CPUs or GPUs that generate significant thermal output. If your device runs hot, this 10mm height and small surface area will not provide enough thermal mass. You will need a larger, fan-equipped cooler for demanding tasks.
Verdict: This is a practical, low-profile passive heatsink for small, low-power components. It offers easy installation and fits tight spaces well.
Awxlumv 25mm Heatsink Key Specs
Material: anodized aluminum
Anodized aluminum provides a durable surface that resists corrosion and improves heat transfer efficiency compared to bare metal. This finish helps maintain consistent thermal performance over time without degrading. You benefit from a long-lasting component that does not require additional protective coatings. When shopping for CPU air coolers, note that most use raw aluminum or copper, while this passive unit relies on this specific treated surface for optimal dissipation in small form factors.
Dimensions: 25 x 25 x 10mm
These compact measurements define the physical footprint and height of the heatsink. A 10mm height offers minimal profile clearance, making it suitable for tight spaces where standard CPU coolers cannot fit. You can install this on small chips or components without interfering with surrounding parts. Compare this size to full-sized tower coolers which often exceed 150mm in height. This small dimension is critical for embedded systems or accessories like the ASUS ROG Ally where space is severely limited.
Mounting Type: Pre-applied thermal conductive tape
The pre-applied tape simplifies installation by removing the need for separate adhesive glue or screws. You simply peel and stick the unit to the target component, ensuring immediate contact for heat transfer. This method is convenient for quick repairs or permanent fixes on flat surfaces. Unlike traditional air coolers that require complex bracket systems, this tape approach is ideal for small electronic devices. Ensure the surface is clean before application to maximize the thermal conductivity of the adhesive layer.
Cooling Method: passive cooling
Passive cooling relies entirely on natural air convection and the heatsink's surface area to dissipate heat, with no moving parts. This results in silent operation with zero noise output, which is beneficial for quiet environments. You do not need to manage fan speeds or worry about mechanical failure. However, passive cooling has lower thermal capacity than active fans. When comparing to CPU air coolers, remember that this method is best for low-power components rather than high-heat processors.
Compatible Device: ASUS ROG Ally
This heatsink is explicitly listed as compatible with the ASUS ROG Ally handheld console. This specific compatibility indicates the unit is sized and shaped to fit the internal thermal requirements of this gaming device. You can use it to enhance cooling performance for specific chips within the handheld. When shopping for CPU air coolers, note that this is a specialized application rather than a general-purpose desktop solution. It serves as a targeted accessory for maintaining optimal temperatures in portable gaming hardware.
Design and Build Details
According to the listing, this heatsink is built from black anodized aluminum. This material choice offers a durable surface that resists corrosion. The anodizing process also improves heat transfer efficiency compared to bare metal. You get a component that maintains thermal performance over time without degrading. The listing specifies a weight of 5.7 grams per unit, or 0.2 ounces. This light weight makes it easy to integrate into tight spaces without adding significant mass to your device.
The physical dimensions are 25 x 25 x 10mm, which equals 0.98 x 0.98 x 0.39 inches. The base features a pre-applied thermal conductive adhesive tape. This mounting type allows for convenient installation without needing additional glue. You can stick it directly onto small components like PC chipsets, power ICs, or LED devices. The fin layout consists of 8 x 8 fins. This structure provides passive cooling for heat-generating parts.
The listing notes compatibility with devices like the ASUS ROG Ally, 3D printers, and NEMA 17 motors. The black finish is consistent across the unit. You benefit from a compact solution that fits where larger coolers cannot. The small footprint ensures it does not interfere with nearby components. This design suits applications where space is limited and airflow is minimal. The adhesive backing simplifies the setup process for DIY projects.
Setup and Everyday Use Guide
Installing this heatsink requires no tools or additional adhesives. The listing specifies a pre-applied thermal conductive adhesive tape backing. You simply peel off the protective layer and press the unit onto the target component. This design eliminates the need for screws, clips, or separate thermal paste application. The process is straightforward and reduces the risk of misalignment during placement. The compact dimensions of 25 by 25 by 10 millimeters allow for installation in tight spaces. You can mount this on small chips where larger coolers do not fit. The passive cooling method means there are no moving parts to maintain. You will not need to worry about fan noise or dust accumulation on blades. This makes it suitable for environments where silence is a priority. The heatsink is compatible with various small electronic components. You can use it on computer PC chipsets, power ICs, and LED light devices. It also fits passive cooling applications for 3D printer parts like NEMA 17 stepper motors. The listing notes it is a perfect fit for the ASUS ROG Ally. This suggests you can use it to manage heat on handheld gaming devices. The black anodized aluminum construction helps dissipate heat efficiently without active airflow. You benefit from a low-profile solution that stays out of the way. The lightweight design at 5.7 grams per unit ensures minimal added mass. This is ideal for portable electronics where weight matters. The setup is quick, and everyday use involves no ongoing maintenance. You place it, and it works continuously to lower component temperatures.
Before You Buy This Heatsink
This small heatsink is designed for passive cooling on low-heat components. You must verify that your target device generates minimal thermal output. High-power chips will overheat without active airflow. The pre-applied adhesive tape simplifies installation, but surface flatness is critical for proper contact. You should clean the component surface with isopropyl alcohol before application to ensure maximum thermal conductivity. This unit is not a replacement for standard CPU air coolers in desktop PCs. It suits niche applications like LED strips, power ICs, or specific handheld consoles like the ASUS ROG Ally. Check your device’s height clearance carefully, as this unit is only 10mm tall. Other listings may offer larger footprints or different heights. Compare the 25x25mm base against your component’s heat spreader size. If your chip is larger, this heatsink will be insufficient. Keep spare units handy, as the package contains six pieces. This allows for redundancy or use on multiple small components simultaneously.
Check before you buy
- Confirm your component’s heat output is low enough for passive cooling.
- Measure your target surface to ensure it fits the 25x25mm base.
- Check vertical clearance to accommodate the 10mm height constraint.
- Clean the mounting surface thoroughly before applying the adhesive tape.
- Verify compatibility with your specific device, such as the ROG Ally.
