Review on 🔥 Enhanced Cooling Performance: 30 PCS Raspberry Pi 4 Heatsink Kit with Thermal Conductive Adhesive Tape, Aluminum and Copper Heat Sink for Raspberry Pi B B+ 2/3/4 by Delbert Potter

My Raspberry Pi 4 got a little hot and I needed to cool them down. They are good quality and already have a thermal backing so just stick them on and you're done. Different sizes for different needs and the price is really good compared to others. You can use them individually, but if you really want to cool your Pi, combine them with a fan (30mm or 40mm) and you should be able to drop the temperature by at least 15-20C.
