System overheating & shutting down

[Deblaere]

Given:
mobo MSI 875P Neo-FIS2R & Pentium4 3Gh FSB800.

Situation:
CoreCenter:

Frequently temp reaches 80°C and more, and then of course system shuts down itself.

Standard heat sink on processor.
Fan is working.
5 other fans in case, all at 3000 rpm.

Please advise.
Thanks.

Welcome to the Forums Deblaere. Pop the case open and confirm that the latches are keeping the heatsink in firm contact with the CPU core, for starters. Also, was the stock heatsink's black-coated thermal pad nice and flat, not kinked or wrinkled?

Heat sink properly mounted & looks normal.

I should add that there are 2 Seti clients running.
(on -cpu 0 & -cpu 1)
When I stop the clients, temp drops immediately to 50 à 55°C.

It should be able to handle 2 Seti clients.
Have another one (Intel mobo & Pentium4 3Gh FSB533),
temp processor between 60 & 62°C.

Should I use a special heatsink for the MSI mobo?

I agree that it should be able to handle two SETI clients without getting out of control (inserts subliminal message, the AnandTech distributed-computing team wants YOU ). If you were interested in an extra-high-capacity heatsink for it, Alpha's PAL8942, Thermalright's SLK-900U, Zalman's CNPS7000-CU or Swiftech's MCX4000 are some of the best of the best. SVC.com has good prices on heatsinks usually (link) and carries all of those ones.
