Thank you!Package includes: 4pcs/set X Heatsink Block Review: Great for graphics card backplates - I have a 3080 hybrid and the vram temps were horrible even thought the cooler keeps the gpu it’s self very cool. With just 4 of these I was able to reduce vram temps by 6-8c while increasing my power limit and reducing fan noise. Definitely way easier than replacing thermal pads if you have a water cooled card already. Review: as described, one very slightly bent pin - what can i say its a cut aluminum brick and its the right shape ## Features - Material: 40mm heat sink anodized aluminum balck - Heatsink Size:40mm x 40mm x 11mm / 1.57" x 1.57" x 0.43"(L*W*H) - The fins increase the area of the board and thus provide for greater heat transfer. - Widely used for computer, Power Transistor, FET, IC, Power Amplifier, Voltage Regulator, MOSFET, SCR etc. - This 40mm heatsink kit is suitable for cooling applications such as 3D printer stepper motor NEMA17, gpu backplate, PC chipset, power IC, power electric device, TEC1-12706 Thermoelectric module, LED light devices etc. Can be used with other devices to cool processors, regulators, etc. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07SKP8FHM | | Best Sellers Rank | #1,835 in Heatsinks | | Brand | Awxlumv | | Brand Name | Awxlumv | | Cooler Heatsink Compatibility | 3D Printer Stepper Motor, Nema 17, Peltier Thermoelectric Module TEC1-12706, Peltier Thermoelectric Module TEC1-12703, Peltier Thermoelectric Module TEC1-12710 Cooler Heatsink Compatibility 3D Printer Stepper Motor, Nema 17, Peltier Thermoelectric Module TEC1-12706, Peltier Thermoelectric Module TEC1-12703, Peltier Thermoelectric Module TEC1-12710 See more | | Cooler Heatsink Material | Aluminum | | Customer Reviews | 4.6 out of 5 stars 17 Reviews | | Included Components | 4Pcs 40mm x 40mm x 20mm heatsink | | Item Dimensions L x W x H | 1.57"L x 1.57"W x 0.43"H | | Item Weight | 0.07 Kilograms | | Manufacturer | Awxlumv | | Model | 20-40 heatsink | | Mounting Type | Panel Mount | | Part Number | 20-40 heatsink | | Product Dimensions | 1.57"L x 1.57"W x 0.43"H | | UPC | 703145002921 | ## Images ![4 Pcs Heatsink 40 x 40 x 11mm / 1.57" x 1.57" x 0.43"(LWH), Aluminum Radiator Heat Sink Cooling Cooler Fine for Computer, Power Transistor, FET, IC, Power Amplifier, Voltage Regulator, MOSFET-Black - Image 1](https://m.media-amazon.com/images/I/611ikfgS+QL.jpg) ![4 Pcs Heatsink 40 x 40 x 11mm / 1.57" x 1.57" x 0.43"(LWH), Aluminum Radiator Heat Sink Cooling Cooler Fine for Computer, Power Transistor, FET, IC, Power Amplifier, Voltage Regulator, MOSFET-Black - Image 2](https://m.media-amazon.com/images/I/51uIredsuPL.jpg) ![4 Pcs Heatsink 40 x 40 x 11mm / 1.57" x 1.57" x 0.43"(LWH), Aluminum Radiator Heat Sink Cooling Cooler Fine for Computer, Power Transistor, FET, IC, Power Amplifier, Voltage Regulator, MOSFET-Black - Image 3](https://m.media-amazon.com/images/I/51zESYD1yHL.jpg) ![4 Pcs Heatsink 40 x 40 x 11mm / 1.57" x 1.57" x 0.43"(LWH), Aluminum Radiator Heat Sink Cooling Cooler Fine for Computer, Power Transistor, FET, IC, Power Amplifier, Voltage Regulator, MOSFET-Black - Image 4](https://m.media-amazon.com/images/I/51siiFRrNWL.jpg) ![4 Pcs Heatsink 40 x 40 x 11mm / 1.57" x 1.57" x 0.43"(LWH), Aluminum Radiator Heat Sink Cooling Cooler Fine for Computer, Power Transistor, FET, IC, Power Amplifier, Voltage Regulator, MOSFET-Black - Image 5](https://m.media-amazon.com/images/I/71CZW6XxpgL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great for graphics card backplates *by D***N on May 11, 2021* I have a 3080 hybrid and the vram temps were horrible even thought the cooler keeps the gpu it’s self very cool.
