The Alpha
PEP66 is a specialised cooler made for Flip Chip Pin Grid Array (FC-PGA)
processors like the Socket 370 Pentium III and Celerons from the 533A model
upwards. Its angled design makes it a lousy fit on many normal motherboards,
but if you're using an FC-PGA CPU on a slotket adapter card, plugged into
a Slot 1 motherboard, the PEP66 is perfect.
It's got little plastic feet, just
like the PAL15, so I had to use the second spacer again. With the second
spacer and using its stock 4800RPM fan, it scored 0.7°C/W, so without it,
it'd be down around 0.64°C/W. About even with the PAL6035, in other words.
