## Description

Product description A heat sink is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device, thereby allowing regulation of the device's temperature at optimal levels. 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). 9mm anodized aluminum heatsink; Dimension: 0.35 x 0.35 x 0.20 inch / 9 x 9 x 5mm (L*W*H) Product Feature Aluminum Alloy Aluminum alloy, great function for heat dissipation. Reduces CPU and LAN Temperature in enclosed and overclocked environments. Easy to Use Pre-applied blue thermal conductive adhesive tape backing, easy attach to the application with no cutting to do. Widely Application Can be applied for cooling VRM GPU Motherboard MOSFET Voltage Regulators, chips, stepper motor driver module and other small electronics that didn't come with any cooling.

Review: Effective Heat Dissipation in a Compact Design – Perfect for Electronics Projects! - The Jienk 4PCS Black Aluminum Heatsink Set is an excellent addition for anyone looking to manage heat effectively in their electronics projects. With 40×40×20mm dimensions and included thermal conductive adhesive tape, these heatsinks provide reliable cooling in a compact, easy-to-apply package. Here’s why they’re a great choice for managing temperature in small to medium-sized electronics setups. High-Quality Aluminum for Efficient Heat Dissipation Each heatsink is made from high-grade black aluminum, known for its excellent thermal conductivity. This material allows heat to dissipate quickly and efficiently, keeping temperatures down in small electronics like Raspberry Pi units, transistors, and other high-heat components. The size and design provide ample surface area for effective cooling, even in tighter setups. Compact and Versatile Size The 40×40×20mm size is ideal for compact setups, fitting neatly on a variety of components without taking up too much space. The low-profile design makes it versatile for use in enclosed cases or small devices, where space is limited but effective cooling is essential. This size makes the heatsinks compatible with many electronics projects, from custom PC builds to embedded systems. Thermal Conductive Adhesive Tape for Easy Installation Each heatsink comes with thermal conductive adhesive tape, making installation straightforward and eliminating the need for additional adhesives or thermal paste. The tape provides a secure bond to components, ensuring maximum thermal transfer and stability. The adhesive holds up well over time, so there’s no worry about the heatsinks detaching during extended use. Durable and Corrosion-Resistant The black anodized aluminum finish adds durability and a layer of corrosion resistance, which is particularly valuable for long-term use in various environments. The heatsinks are built to withstand wear and environmental factors, maintaining performance even in challenging conditions, making them a dependable choice for both indoor and outdoor electronics setups. Great for Electronics Cooling Applications These heatsinks are perfect for a range of applications, from cooling processors and transistors to other heat-sensitive components. I’ve used them in small DIY projects and larger electronics, and they perform well across the board, keeping temperatures manageable and preventing thermal throttling. The ease of application makes them suitable for beginners and experts alike. Minor Considerations While these heatsinks are effective, they’re most suitable for components with moderate heat output. For extremely high-power electronics, a larger or active cooling solution may be necessary. However, for most standard electronics projects, they provide more than adequate heat management. In summary, the Jienk 4PCS Black Aluminum Heatsink Set is a reliable, easy-to-use cooling solution for various electronics projects. With efficient heat dissipation, durable construction, and convenient adhesive tape, these heatsinks are a fantastic choice for anyone looking to improve thermal management in compact electronic devices. Highly recommended for DIYers and hobbyists who need a simple yet effective solution to prevent overheating!
Review: Really great value, and fit perfectly on SFP+ copper network modules - These little heatsinks are just the right size for cooling copper SFP+ network modules. They fit perfectly in the space between the RJ45 connector and the switch. SPPs get 𝙫𝙚𝙧𝙮 hot - too hot to touch many times. These bring the temperature down really fast, and improve performance.

...over an I/O chipset. Just peel and stick; it stays put. It's been holding vertical on motherboards in (2) full tower cases since 05-25. Added Noctua NF-A4x20 PWM fans from Amazon as well. Second chip of the X670 AMD I/O chipset was getting hot (~65-70°C) when making large file transfers between NVMe drives over a 10Gb network. Chips are rated to 95°C, but trying to keep temps down for longevity. Chip temp now stays at 60° max, with normal loads at about 50-52°. Pics show about where the 2nd X670 chip is on a Gigabyte Aorus Elite AX motherboard.
