How each alternative compares
Awxlumv 150mm Large Aluminum Heatsink
This 150x93x15mm heatsink is significantly larger than the 25mm original. It measures 5.91 inches long and weighs 10.9 ounces, compared to the tiny 0.98-inch base and 1.27-ounce weight of the reference model. You gain substantial surface area for high-wattage components like power amplifiers or MOSFETs. You lose compactness, as this unit requires ample space to mount. It is best for builders with room to spare who need passive cooling for high-heat sources. The original fits tight spaces like the ASUS ROG Ally, while this large plate handles heavier thermal loads in open chassis environments.
Awxlumv 40x40x20mm Aluminum Heatsink
The 40x40x20mm heatsink offers a middle ground in size. It is larger than the 25mm base but smaller than the heavy-duty plates. At 1.57 inches square and 0.79 inches tall, it provides more surface area for VRMs or 3D printer motors. It retains the adhesive mounting style, making installation as simple as the original. You get better coverage for medium-sized chips without the bulk of the 100mm models. This option suits users who need to cool multiple components quickly. The original is too small for these tasks, while this unit bridges the gap between small chipsets and large power transistors.
Awxlumv 100x69mm Aluminum Heatsink
This 100x69x36mm heatsink is a robust single unit designed for maximum surface area. It measures 3.94 inches long and 1.42 inches tall, weighing 9.14 ounces. This is far heavier and larger than the 25mm original. It is ideal for high-power GPU cooling or power transistors where space allows. You sacrifice portability and ease of use in tight spots. The original fits small devices like chipsets or the ASUS ROG Ally. This large aluminum plate is for spacious cases where passive cooling requires significant mass and fin density to dissipate heat from high-wattage components effectively.
Awxlumv 100x100x18mm Aluminum Heatsink
The 100x100x18mm passive heatsink provides a square footprint of 3.94 inches. It is much wider than the 25mm original but slightly thinner at 0.71 inches tall. It is designed for simple passive cooling of MOSFETs and ICs in compact enclosures. You gain a large, uniform base for even heat distribution. You give up the tiny form factor that makes the original suitable for small electronics. This unit is better for power components that generate more heat than small chipsets. It offers a stable, passive solution for builders who need a reliable aluminum block for moderate thermal loads.
Awxlumv 120mm Aluminum Heatsink
This 120mm heatsink measures 4.72 inches long and 1.06 inches tall. It offers substantial surface area for passive cooling tasks. Weighing 7.76 ounces, it is much heavier than the lightweight 25mm original. It fits users who need a robust, single-unit solution for high-heat components like MOSFETs or NVMe drives. You trade the compact, adhesive-backed convenience of the original for significant thermal capacity. This option is for builders with space for a larger plate. The original is limited to small components, while this unit handles higher power dissipation in open-air passive cooling scenarios.
Awxlumv 50x50x20mm Aluminum Heatsink 4-Pack
The 50x50x20mm heatsink comes in a 4-pack. Each unit is 1.97 inches square and 0.79 inches tall. This is larger than the 25mm original but remains compact enough for medium-sized chips. It is made of durable aluminum, suitable for routers or power components. You get multiple units for cooling several areas at once. The original is a single small piece. This pack offers better value for cooling multiple medium-heat sources. It retains a similar passive cooling approach. Choose this if you need to cover more surface area than the tiny 25mm base allows, without moving to the larger 100mm plates.
