OK - here's the resolution after working for a few days with Intel tech
support.
The P4 550 3.4G chip will happily chug along as long as it does not exceed
73.2C, so running at 70C under full load is within parameters. The fix for
the overheating alerts was not what I expected - I had to remove ALL the
extra fans that were installed leaving just the CPU fan, the rear case
exhaust fan and the PS fan. Seems like the "thermally approved" cases for
the P4 need to have unrestricted air flow. Even though the extra fans were
in the proper orientation re intake/exhaust it somehow changed the flow over
the CPU. Go figure. Took all the fans out and ran it at full load for 6
hours and it stayed happily at 68 - 70C. Tested by putting each fan in
individually and running again and then removing. The temps increased by 1
or 2C in each case. Good airflow around the side and rear of the case is
critical also. I had the case six inches from a wall on the left ( vented)
side and the temp increased - moved it diagonally and temp went back to
"normal".
Anyhow, that's my saga, the P4 seems happy as a clam. Maybe this info will
help someone else.
Thanx for the help and suggestions,
Vic
