proper fcpga heatsink mounting?

[gotser]

I bought a heatsink/fan for my fcpga celeron and i'm starting to think it's not mounting correctly. the heatsink is just plain flat on the bottom and only touches the small top of the cpu. is this correct or do i have the wrong kind of heatsink? Shouldn't the heatsink have a small recess for the chip?

this could explain why my celeryfart 566 wont post above 566! Argh!

nope thats the way heatsinks are, at least any i've ever had.

You do have heatsink compound between your heatsink and CPU, right? If not, it is essential overclocked or not.

Does your heatsink have feet like the PEP66? If not, it may not be sitting flush to the CPU. On the flip-chips, normal PPGA heatsinks must be carefully positioned or they won't help much.
