7pcs Black Aluminum Heatsinks & 4pcs Copper Heatsinks Cooler Cooling Kit for Orange Pi OPi 5/5B/5 Plus,Orange Pi 5/5B/5 Plus Heatsink Cooler Kit for Orange Pi 5/5B 4GB/8GB/16GB/32GB (11pcs)

These are good little heatsinks for any electronics. They stick on easily and make a big difference.

This is a set of add-on heatsinks for the major chips in an OrangePi5 and OPi5PlusThey arrived in a nice storage case and include a range of suitable sizes. Some are black while others are copper coloured although at this size the colour won't affect performance noticeably but they look good.The base is a pre-attached thin thermal tape with the outer stickly side protected by a blue peel off covering.The glue was moderately tacky and while that might allow a second go at positioning that is best avoided. Cleaning the chip's upper surface by wiping over with a cloth moistened with a little cleaner/degreaser like isopropyl alcohol is the best preparation for good even adhesion.Once the cleaner is evaporated peel back the blue covering, take aim and press into place.I've found that the adhesive on these thermal adhesive strips gets stronger once they have been heated up so you can put the Pi into use once all the heatsinks are in place
