This set of heatsink is low profile (0.43" / 11mm) and made from 6063-T5 aluminum alloy with high thermal conductivity, structure stability and light weight. The heatsink extrusion is in vertical and horizontal grooves, that is greatly increases the heat dissipation function. The surface of extruded aluminum is anodized. This kit of heatsink comes with 40x40mm pre-applied thermal conductive adhesive tape, for easy installation and optimum heat conductivity. Material: Extruded Aluminum 6063-T5 Coating: Anodized Dimension: 1.6" x 1.6" x 0.4" / 40mm x 40mm x 11mm (L*W*H) Weight: 0.6 oz / 17 gr per piece Mounting Style: SMD/SMT Fin Style: Vertical Number of fins: 11×13 Standard: RoHS compliance Pre-Applied Thermal Conductive Adhesive Tape This kit of heatsink comes with 40mmx40mm pre-applied thermal conductive adhesive tape for easy installation, strong adhesion and premium thermal conductivity. Divers application This set of 40mm heatsink is perfectly fit for cooling 3D printer stepper drive, Nema 17, Thermoelectric Peltier Cooler Module, Electronic Devices, Robotic Projects, LED Modules, Telecommunication Devices, Wi-Fi Routers, Medical Devices, Solar Invertors, Servers, Industrial Applications, Amplifiers and Audio Equipment, Power Supplies. Perfect fit for 3D Printer Motor Name 17 Thermoelectric Peltier Module Review: Good so far - Used these on a grow light to help keep it cooler. It didn't get hot enough to burn you if you accidentally touched it or anything, but I figured, why not? Gives me a little more piece of mind leaving them on all day when im at work. Definitely drops the temps and looks neat, and adhesive sticks very well. Review: Works well and easy to use - I put 8 of these on my DC DC battery charger in my camper van. Keeping the charger several degrees cooler than it was before. The adhesive bottoms work well. Seems like good value for the money. The small size also makes them versatile. ## Features - 40mm anodized aluminum heatsink - Pre-applied 3M 8810 thermal conductive double side adhesive tape backing - Can be applied for passive cooling of 3D printers stepper motor, NEMA 17, TEC1-12706 Thermoelectric Peltier Cooler etc. - Dimension: 1.57 x 1.57 x 0.43 inch / 40x40x11mm (L*W*H) - Weight: 0.6 oz / 17 gr per pc ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07D4FVC61 | | Best Sellers Rank | #71 in Heatsinks | | Brand | Easycargo | | Brand Name | Easycargo | | Cooler Heatsink Compatibility | 3D Printer Stepper Motor, Nema 17, Peltier Thermoelectric Module TEC1-12703, Peltier Thermoelectric Module TEC1-12706, Peltier Thermoelectric Module TEC1-12710 Cooler Heatsink Compatibility 3D Printer Stepper Motor, Nema 17, Peltier Thermoelectric Module TEC1-12703, Peltier Thermoelectric Module TEC1-12706, Peltier Thermoelectric Module TEC1-12710 See more | | Cooler Heatsink Material | Aluminum | | Customer Reviews | 4.7 out of 5 stars 635 Reviews | | Included Components | Heatsink 40mmx40mmz11mm with thermal conductive adhesive tape | | Item Dimensions L x W x H | 1.57"L x 1.57"W x 0.43"H | | Item Weight | 17 Grams | | Manufacturer | Easycargo | | Model | 404011B04-8810 | | Mounting Type | Panel Mount | | Part Number | ES-04B404011 | | Product Dimensions | 1.57"L x 1.57"W x 0.43"H | ## Product Details - **Brand:** Easycargo - **Cooler Heatsink Material:** Aluminum - **Item Weight:** 17 Grams - **Product Dimensions:** 1.57"L x 1.57"W x 0.43"H ## Images ![4pcs 40x40x11mm - Image 1](https://m.media-amazon.com/images/I/61emkT6E1+L.jpg) ## Available Options This product comes in different **Number Of Items** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good so far *by A***T on April 18, 2026* Used these on a grow light to help keep it cooler.

I added 1 heatsink to each side and the temperature difference was remarkable. It was actually cool to the touch. ## Frequently Bought Together - Easycargo 40mm Heatsink Kit 40x40x11mm + 3M8810 Thermal Conductive Adhesive Tape, Cooler Aluminum Heat Sink for Cooling 3D Printer Stepper Motor TEC1-12706 Thermoelectric Peltier Module 40mmx40mmx11mm - TEC1-12706 12V 60W 6A 40MMX40MM Heatsink Thermoelectric Cooler Cooling Peltier Plate Module 10pcs Compatible with Gaming Consoles/Devices - GENNEL G109 10gram Thermal Conductive Glue, Heatsink Silicone Glue, Thermal Plaster, Silicone Viscous Adhesive Compound for LED GPU MOSFET Printer Chipset IC High Performance --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.nz/products/65603454-4pcs-40x40x11mm](https://www.desertcart.nz/products/65603454-4pcs-40x40x11mm) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-06-01*
