Review on Alphacool Copper Heatsinks 6 5Mm 10 Pack by Donnell Cursed

Quality control needs improvement, had to straighten most of the fins on these out of the box. Reason for 4 stars. That being said, these are fantastic little heatsinks that do an excellent job of dissipating heat away from the components. I used them to cool the power supply chip and other controller chips on my raspberry pi 4b. This allowed increased acceleration with more stable performance. I used custom made thermal epoxy to glue them on. It is made by Tech Ingredients. When doing this with yours, just make sure the surrounding areas are covered with a conformal layer.
