The fins on the heat sink are also stiff enough so you can mount a fan onto the heat
sink (blowing onto the top of the Alpha chip) without removing/drilling the heat sink.
Find a fan with mounting holes at the right spacing (I used a pentium cpu fan) and
you're all set. I just had to look around at a few pc clone shops, and I found one that
