Chip overheating

Hi folks. I wondered if I could get ideas from you.
I just assembled a new desktop PC using an
Intel D865PERL mobo
Intel P4 Prescott 3.2 Ghz CPU
My old ATX case and a new powersupplymemeoryetc...

And this cooling fan

I fired it up for the first time last night and it runs for about 20
seconds and shuts off.
I think it's overheating. I say this because if I go into BIOS /
Hardware Profiles, I can watch the temp rise up to 217F whereupon it
shuts off. 217, every time.
When it cools and I reboot it says onscreen it shutdown per overheat
I took my shopvac, reversed it so it blew from the hose, put the vac
outside so it sucked in cold air and blew the airstream across the
heastsink for the CPU chip and rebooted. It kept it at a cool 174F and
it ran and ran and ran.
I think it's overheating.
Why won't this fan keep this thing cool.
Is there a better fan to use?
Is it the Prescott chip?

174F seems a tad hot. Yes, the Prescott runs hotter than the Northwood but I
wouldn't expect it to be that much. My 3.0 Northwood, in an old ATX case
with the stock retail HSF under a 50% constant load, runs around 138F in a
74F room.

Better HSF? Zalman all copper. Approx. $50 (USD)

Better case too, maybe. If your case is congested with wires and devices
there is no room for air to circulate. Additional fans - maybe a 120mm on
the back and a 92mm on the front to get that wind tunnel effect. Cases sans
PSU run around $50 (USD) and fans run around $10 (USD).

All cheap insurance.

20 seconds is not very long for your system to overheat. I've got 2
D865PERL systems, one with 3.0c & the other 3.2e and though under heavy
loads zone #2 overheats on active monitor, I'm not experiencing anything
close to your issues. I'm using the stock HS/Fan that came with the boxed
processors. Be sure you're getting contact with the heat sink and using
decent thermal compound. Abandoning my old ATX case for a newer Tsunami
made a world of difference:
And if you don't mind spending a lot of money, one of these water cooled
versions works even better for one of my friends:
Good luck!

I do think the fan is deficient. I got it running better last night.
Reseated the HSF with more goop. Hardware monitor shots just into the
red with no load. With load, it jumps further into the red.
I'm going to try to find a new chip with Northwood core and better fan.

I put together one of those ASUS micro towers last weekend, with a
Semperon (sp?) 2500+ chip and 512M. CPU runs about 42C after a day of
