Alpha had managed to create a heatsink that lasted about two years and worked with three different types of CPU, this was the PAL-6035 which worked with socket 370, socket 7, and socket A even though it was made before this socket was released/made. It's main design plus was the copper insert that actually made contact with the processor and, as we all know copper is a better heat conductor than aluminum, while aluminum releases its heat much quicker.
