The heatsink, OTOH, had a little plateau on the bottom of it about an inch wide. That is the only part of it that was in contact with the CPU, don't ask me why it was designed that way! After I got done with it, the CPU and heatsink fit together so nicely it was like they were drawn together. Then I put a thin layer of heatsink grease between them. The lapping made a big difference because now a much larger surface area is being cooled. > > > > www.pcpowercooling.com sells heavy duty heatsink/fans for many processors > > including the K6/2.
