Its compact design maximizes heat dissipation while maintaining a lightweight profile, reducing hardware failure risks and ensuring silent, efficient operation. ## Description The Heat sinks are used with high-power semiconductor devices such as power transistors and optoelectronics such as light emitting diodes (LEDs), where the heat dissipation ability of the component itself is insufficient to moderate its temperature.Made of high quantity aluminum, good thermal conductivity.Reduce the risk of hardware failure due to overheating.Designed to maximize its surface area in contact with the cooling air.Light weight and used in applications where weight is a big concern.Widely used in Computers GPU HDD etc., for Power Transistors, FETs, ICs, Power Amplifiers, Wifi Routers, Voltage Regulators, MOSFETs, SCRs, FET, IC etcHeatsink Features：Size:2.71" x2.71" x 1.41" /69 mm x 69mmx 36mmMaterial: Aluminum 6063-T5Fin: 27Color: Silver Weight: 6.13 ozQuantity: 1 Review: Good Product, strongly recommend. - This heatsink is really impressive for the price. I've used several different heatsinks, but when this one was first delivered, I was surprised by how clean and well-finished it was. There were no rough edges or scratches, and no blur around the edges either. A lot of Chinese-made heatsinks tend to have unfinished edges or sharp spots, but this one is exceptionally well-made. On top of that, the price is very reasonable. I'm using two of these on NVMe enclosures with thermal pads, and they do an excellent job of transferring heat. Even without a fan, the setup stays clean, efficient, and the color matches perfectly too. Review: うまく放熱してくれてます。 - 私のゲーミングノートPCの電源アダプターは240wで、動画エンコードや動画のアップスケーリングなどを行い負荷をかけると、手で触れられないほどの発熱をしてて、これは良くないと思い、本製品を2つ購入。 電源アダプターの上面と下面にそれぞれ本製品を置いたところ、触っても「温かいな」くらいの温度になるまでうまく放熱してくれてます。ちょうど大きさもぴったりでした。 同じ感じで高温に悩んでる方いらっしゃいましたらこの商品はおすすめです。 ## Features - 1. Product Name: large heat sink ( anodized aluminum heatsink); Material: aluminium; Color: sliver.（Sufficient materials only for excellent quality） - 2. Size: 2.71 x 2.71 x 1.41 inch / 69 mm x 69mmx 36mm (L*W*H) - 3. The Quantity of fins: 27pcs; Base board thickness:4.6mm, Fins board thickness:0.6-1mm; Fin spacing:1.99-2.12mm; Fin height: 31.4mm; The fins increase the area of the board and thus provide for greater heat transfer. - 4. This large big aluminum heatsink is passive cooling, The 27pcs fins increase the area of the board and thus provide for greater heat transfer, reduces the risk of hardware failure and power loss due to overheating, more safety. - 5. Widely used in Computers GPU HDD etc., for Power Transistors, FETs, ICs, Power Amplifiers, Wifi Routers, Voltage Regulators, MOSFETs, SCRs, FET, IC etc - 6. Packaging: 1 x anodized aluminum heatsink. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07TJXN1WB | | Brand | Awxlumv | | Brand Name | Awxlumv | | Cooler Heatsink Compatibility | Aluminum | | Cooler Heatsink Material | Aluminum | | Cooler heat-sink compatibility | Aluminum | | Cooler heat-sink material | Aluminum | | Customer Reviews | 4.6 out of 5 stars 440 Reviews | | Included Components | 1 PCS Large Aluminum Heatsink | | Item Dimensions L x W x H | 6.9L x 6.9W x 3.6H centimeters | | Item Weight | 6 Ounces | | Item weight | 6 Ounces | | Manufacturer | Awxlumv | | Model | 69x69x36 mm | | Mounting Type | Panel Mount | | Mounting type | Panel Mount | | Part Number | 69x36mm | | Product dimensions | 6.9L x 6.9W x 3.6H centimeters | | UPC | 703145002952 | | Unit Count | 1 Count | ## Product Details - **Brand:** Awxlumv - **Cooler heat-sink compatibility:** Aluminum - **Cooler heat-sink material:** Aluminum - **Item weight:** 6 Ounces - **Product dimensions:** 6.9L x 6.9W x 3.6H centimeters ## Images ![Large Aluminum Heat Sink 2.71"x2.71"x1.41"/ 69x69x36mm Heatsink High Power Cooling Plate 27 Fin Radiator GPU Cooler IC Module PC Computer Led PCB Charger Electronics Amplifier - Image 1](https://m.media-amazon.com/images/I/61Fp5NAR3-L.jpg) ## Available Options This product comes in different **Model** options. ## Questions & Answers **Q: I’m looking to cool a couple of thick film resistors that keep overheating. Can I cool more than one (2) with this heat sink?** A: I would think so. It depends on how much power they are dissipating and how much airflow is on the heatsinc **Q: Is this anodized? Also what is the alloy?** A: It's very shiny which might lead one to believe that it has been clear anodized because it doesn't have that dull grey look of raw aluminum that's been left out for a while. I have no clue about the alloy. The packaging says nothing about the finish or the alloy. **Q: Can you make anodized 200 x 138 x 36mm block? Thanks.** A: Hi 69x36mm HeatsinK, already all silver oxide item surface, you can use two side by side to dissipate heat for electronic products, thank you **Q: What is the thermal resistance of this heat sink in the 400mm version?** A: Short answer: About 0.4 oC/W/16in (still air). For others who purchased a different length, they will need to adjust this number. From my review below, a more detailed answer: I found a dimensionally-similar (2.581" wide instead of 2.71", 1.340" tall instead of 1.41" tall) heat sink in an online AAvid catalog, model # 83220. The AAvid heatsink specs were 1.01 oC/W/3in (still air), so I'm expecting this heatsink could be 10% better (lower). Note that if you bought a length other than 3", the thermal resistance does not scale linearly with 1/Length, assuming a centrally located thermal point source. For the 15.75" length I'm using, the improvement is only a 50% reduction in thermal resistance. Also note that the thermal resistance decreases (improves) with moving air. While the documentation I found for the #83220 did not provide thermal resistance versus air flow, I found another AAvid catalog and heatsink #72070 (dimensions 3.008" wide, 1.02" tall, similar fin aspect ratio, 1.4 oC/W/3in) that provided a thermal performance versus airflow table; for a modest airflow (quiet muffin fan) of ~700 LFM, the thermal resistance drops by about another 70%. Net result, for the 15.75 inch length option, operating with 700 LFM forced air flow, is expected to be about (1oC/W/3in * 90% * 50% * 30%) = 0.14oC/W. My heat source is distributed along the 15.75" length, rather than being a point source in the center, so I expect the actual performance to be 2-3x better (lower resistance) than the above calculation. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good Product, strongly recommend. *by J***N on 13 July 2025* This heatsink is really impressive for the price.

Highly recomend it. *by J***E on 7 April 2026* For $8 dollars delivered it's pretty nice. Very smooth face, fine fins that actually serve to dissipate heat, fine end cuts with no jagged edges, just the right size. Unless you absolutely need something actively cooled with heat pipes or skived copper: this is your clear winner for intermediate size, high quality, passive aluminum heat sinks. Just be sure to arrange the fins vertically so you get a little convective cooling boost from warm air rising. ## Frequently Bought Together - Awxlumv Large Aluminum Heat Sink 2.71"x2.71"x1.41"/ 69x69x36mm Heatsink High Power Cooling Plate 27 Fin Radiator GPU Cooler IC Module PC Computer Led PCB Charger Electronics Amplifier - GENNEL G109 10gram Thermal Conductive Glue, Heatsink Silicone Glue, Thermal Plaster, Silicone Viscous Adhesive Compound for LED GPU MOSFET Printer Chipset IC High Performance - Double Sided Tape 1inch x 66Feet Thermal Tape Heavy Duty Super Strong Adhesive, Insulation Heat Transfer Tape for Paste CPU Heatsink, Mounting LED Strip, Carpet Fixing, Woodworking Project, DIY Crafts --- ## 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.us/products/408537802-large-aluminum-heat-sink-2-71x2-71x1-41-69x69x36mm-heatsink](https://www.desertcart.us/products/408537802-large-aluminum-heat-sink-2-71x2-71x1-41-69x69x36mm-heatsink) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-12*
