GeeekPi 18PCS Pure Copper Heatsinks for Raspberry Pi 5/4B, CPU Cooler with Thermal Conductive Adhesive Tape

These are high quality copper heat sinks that perform much better than the cheaper aluminum heat sinks. I purchased this kit for my Viture AR Glasses which get hot on the right side of the frame. After cleaning the plastic frame with some isopropyl alcohol, I attached one larger and two smaller heat sinks. So far they are holding great but not so much I could not remove the heat sink if necessary. The results were impressive. The glasses used to literally begin causing a minor burning sensation after about 30-45 minutes of use. Now the frame is much cooler and more comfortable. I am sure the product will last longer as well. The amount of weight added was negligible and you can literally feel the heat sinks working if you care to touch them with your hand. I plan on adding a few to the back of my Nvidia 3090 in the future. I also have a few other electronic products that would benefit from additional heat dissipation. These heat sinks are not very large, but they work great and I highly recommend them.

These heat sinks easily dropped my voltage regulator temps by 10C with no additional airflow. Great product! The only issue is that some of the blue "backing" that covers the adhesive wasn't fully cut by the manufacturer, so I had to very carefully cut it with a knife to separate a few of the blocks. Super easy to install, size is perfect for an RPi or something like a BitAxe.

These worked great for my project, I liked the variety in sizes, fit on the chips to reduce heat, I can tell they are working as they get warm to hot pulling heat away. With peal off sticky pads they are easy to apply.

Works amazing! I tested it with my FLIR infrared camera and these little heatsinks clearly pull the heat out much faster! Thanks for a great item!

Excellent assortment of heat sinks. Once placed, they hold very well, even under heat!

Good variety of sizes, very sticky, none have fallen off in several months.

The worked great for my BitAxe 601/602. Just the sizes I needed.

Love it. Arrived on time. Product is exactly as described. I use them to help cool a variety of little DIY projects. Nice and low profile, so they fit everywhere. The adhesive is VERY sticky so make sure you put it where you want it the first time as it’s easy to damage things when removing.

Exactly as expected.

Werkt heel goed. Alles perfect in orde

TOP prima spul.
