CPU overheating

I run a P4 2.4ghz 800fsb chip on a ASUS P4C800 Deluxe Motherboard and I am
having a problem with overheating..

Normal idle temprature seems to be at 34-39 degree's celcius (90ish - 112
degrees farenheit) but whenever I play a game or put the puter thru some
processes like kazaa and lots of downloading the temp will rise twice these
temps all the way till the point the computer shuts down..

I have a case fan, CPU fan (included with chip), and power supply fan which
are all running at the right speeds. I have the thermal goo stuff on it as
well which drops the temp to about 63 degrees celcuis (10 degrees below shut
down temp) during game playing.

case fan positioned at the lower front of case and blows outwards towards
the back of case.... all the pci slot covers are on as well..

I am fairly sure the chip is in flat and so is the heatsink.. anybody have
any ideas about making it cooler ? another case fan ?

The man at the computer shop said "update the bois"... I will - but do you
think the guy is trying to fog me off ?

Check the BIOS setup menu for a shutdown temp setting. If that is the
cause for the shutdown it'll be useful to know, "possibly" adjust.
The possibility to adjust it lies in the fact that the temp sensor
reading could in fact be wrong, which IS something a BIOS update
"might" address. If it can be determined that the BIOS is reporting
false high readings and the BIOS setup is determining the shutoff temp
then you could increase that shutoff temp appropriate to the
difference between actual temp and misreported temp.

On the other hand, even if the system is misreporting the temp, it's
still most likely increasing in temp by the rate shown by the sensors
(or near enough). You might want to remove and reattach the heatsink,
just to see if it makes any difference. If there's too much thermal
"goo" it'll have poor performance, increase the temp.... only a
paper-thin layer is needed.

The optimal fan arrangement is usually with one directly below the
power supply on the rear case wall. If your system doens't have one
there you might add one. That or the front fan should have a fairly
unobstructed air passageway. If that passageway is mostly obstructed
by a stamped-in-metal fan grill, you may need to modify the case, cut
out that grill. If there's potential for wires (or anything else) to
fall into the fan opening after the grill is cut out then install a
wire grill guard (available online for about $1-4 or comes with some
fans).

Removing the PCI slot cover directly underneith the video card can
help to cool it. With a system having a front fan as yours does, and
having the traditional active heatsink (fan ON the heatsink) there is
usually benefit in removing it.

Without seeing your case, configuration, it's difficult to speculate
further about it. You need to assess the airflow yourself, see if
there's adequate openings for intake and exhaust. Tiny holes in
plastic or sheet metal aren't suitable for a modern system.

If you can privide links to some good picures of your case (not
necessarily picures of the acutal case but same model being sold
somewhere (possibly Newegg.com) ) then we might have more ideas.
