“Good quality, solid copper heatsinks for Raspberry Pi 4. Easy to apply, as they have 3M thermal double-sided tape already in place.
These heatsinks have ended the slowdowns from overheating. A grreat product at a good price.”
“Unfortunately, the most important heatsink of the set - the one for the CPU - had no adhesive on it, so it wasn't immediately usable.
Poor Quality Control!”
