Our 40x40x20mm heatsink kit is engineered for enthusiasts who demand both performance and convenience. 1. This 40mm heatsink kit is suitable for a variety of cooling applications such as 3D printer stepper motor NEMA17, PC chipset, power IC, power electric device, TEC1-12706 Thermoelectric module, LED light devices etc. 2. 40mm (L) x 40mm (W) x 20mm (H) extruded aluminum heat sink kit is crafted from premium 6063-T5 anodized aluminum alloy, our heatsink boasts superior heat dissipation. The anodized surface not only resists corrosion and scratches but also increases surface area for faster cooling, effectively protecting your valuable components from overheating. 3. With compact dimensions of 40x40x20mm (1.57"x1.57"x0.79"), this heatsink fits perfectly on a wide range of devices. It's the ideal solution for cooling NEMA17 stepper motors on 3D Printers (like Creality, Ender 3), VRM/MOSFET on GPU boards, Raspberry Pi 4/5 chipsets, LED drivers, and power ICs. 4. Stop worrying about thermal throttling and component failure! Specifically designed to dramatically reduce the operating temperature of 3D printer stepper motors, preventing "heat creep" and ensuring smooth, precise prints. Also essential for stabilizing voltage regulator modules (VRM) during PC overclocking. 40mm aluminum heatsink kit, 40x40x20mm Heatsink 1.57 x 1.57 x 0.79 inch (L*W*H) 40 x 40 x 20mm (L*W*H) Length: 40mm / 1.57inch Width: 40mm/ 1.57inch Height: 20mm/ 0.79 inch Number of fins: 11 Fin Style: Vertical Material: Extruded Aluminum 6063-T5 Base Board thicknesses: 4.2mm/ 0.17inch Fin thicknesses: 1.3mm/ 0.05inch Fin Spacing: 2.52mm/ 0.1inch Unit weight: 1.45 oz / 41 gram per piece Flatter base plate and tick enough base material. Package includes: anodized aluminum heat sink: 4 pcs 40mm aluminum heat sinks. Widely Application 3D Printing NEMA17 Stepper Motor (X, Y, Z, E-axis) - Prevents heat creep for flawless prints. PC & Gaming GPU VRM, MOSFET, RAM, Chipset - Reduces throttling for stable overclocking. Single-Board Computers Raspberry Pi 4/5 SoC, NVMe SSDs - Keeps your mini-computer running cool. Electronics & LED Power Supplies, LED Drivers, TEC1-12706 Modules - Extends component lifespan. 4Pcs Aluminum Heatsink Aluminum radiator has the advantages of beautiful appearance, light weight, good heat dissipation performance and energy saving effect. The surface of good aluminum radiator is anodized to increase the corrosion resistance, abrasion resistance and appearance of the aluminum surface treatment. In computers, heat sinks are used to cool central processing units or graphics processors. Heat sinks are used with high-power semiconductor devices such as power transistors and optoelectronics such as light emitting diodes (LEDs). Note 1). The colors may have difference as the different display, please understand. 2). Please allow 1-2mm error due to manual measurement, please make sure you do not mind before you bid. You just put it on your Xbox 360, VGA card and other equipment. You need to check the size if you want to paste on another product. Review: A good buy - Good quality, well made.
