20PCS Black Aluminum Heat Sink with Thermal Conductive Adhesive Tape, 9×9×5mm Heatsink Cooler for Cooling VRM GPU Stepper Driver MOSFET VRam Regulators

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 DissipationEach 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 SizeThe 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 InstallationEach 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-ResistantThe 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 ApplicationsThese 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 ConsiderationsWhile 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!

I stuck one on an Intel 486DX2-66 that I installed in an old Compaq Deskpro. The adhesive is strong enough to hold it on even under load, and the heatsink dissipates enough heat for an old chip like that. I can easily recommend this for adding cooling to vintage computers that don’t already have it.

I used these to create a heat sink on an LTE modem I set up in a custom enclosure. The self adhesive part worked good and I've had no problems with the piece I used.

The heat sinks worked perfectly on a raspberry pie.

The blue tape was very difficult to remove, took about 3 minutes for me to get one heatsink ready. After it's stuck to the voltage regulator for cooling, it can move around easily due to the sticky foam tape that is a little thick and moves around a lot. Like I said, it works, but just not the perfect thermal adhesive solution.

These are as described but I was mistaken on the size. Well made. Be sure to know what size you need,

These work great for overheating SSD's

Appears to be working as designed.Components are operating cooler.

The adhesive works well.. these generally are working great for my use case.
