I've read many of the posts in this thread. I notice that many upmarket
heatsinks also are mounted on the same type of plastic clips. I recall
coming across such a mountig device many years ago as a technician.
Sometimes the clips would engage firmly, and sometimes they wouldn't. We
found that where the clips did not engage, the board into which they were
meant to lock into was slightly thicker - all it has to be is s few
microns thicker, and it will stop the clips from locking in. Possibly this
is the problem with these CPUs.

It's hard to say. I just did 2 identical P5E motherboards and 2 identical
processor/HSF assemblies.

In both cases, the pins would all latch, if done one at a time. The problem
was that latching the 4th one would always cause 1 of the other 3 to pop
loose. That's because the processor in the socket sits a bit too high (or
the HSF is too short) and the HSF assembly has to bend literally concave
over the processor to get all 4 latched. The processor exerts such a
trmendous upward force in the middle, the latches are going to pop loose no
matter how securly they latch. So the latches do seem to work, they're just
not strong enough to overcome the upward pressure in the middle due to the
too tall processor or too short HSF. Had the legs on the HSF been just a
fraction of an inch taller, it all would have worked.

In my case I got worried that the pressure I was exerting on the pins
would cause damage to the motherboard. I will be looking for a screw
mounted heatsing with a back plate.

I like the mounting security of a backplate, but I'm not ready to have to
remove my entire motherboard every year for a heatsink cleaning.

You dont actually remove the cpu, and scrape off the compound do you? And if
you mean to remove dust, get a small compressor and blow out the dust.
