CPU Overheating - Abit AS8 w/Pentium 4

[k]

Help, my CPU is running hot. Just assembled an Abit AS8 motherboard
with a Pentium 4 530 LGA 775 (3.0GHZ) with Intel's included heatsink
and fan. Initial Abit EQ readings after boot up were:

CPU temp = 82c
System Temp = 24c
CPU Fan = 2460 RPM

Heatsink feels slightly warm to the touch, but definitely not hot.
The computer unexpectedly shutdown a few times when the temp ran into
the upper 80's. (However, Win 2000 automatically began saving
settings before it powered down, so I'm not sure if this was a result
of overheating.)

The CPU was idling at approx. 60c in idle Windows environment. The
heatsink fasteners appear to be engaged correctly, but it's difficult
to be sure since the board flexes so much as they're pushed in. After
pushing some more and aligning heat sink screws perpendicular to the
heat sink, the CPU temp now idles at approx 50c, about 63c immediately
after bootup.

My tower only has one fan, so I left the top off for the time being.

How can I get the temperature down to normal? Also, Intel says that
the pre-applied thermal interface material(TIM) on the heatsink must
be replaced if the heatsink is removed? Will that be difficult
considering how hot the processor's been running? Can Arctic Slver be
used in conjunction with the TIM?

Any help would be greatly appreciated.
Also, any recommendations on a good tower for this setup?

Thanks.

ATI 9200SE 128MB AGP Card
300W Seasonic Power Supply
Tower has just one fan, but I've kept the top off and ambient temp
seems ok, right?

It's not touching the CPU properly. Either that, or you left the clear
protective tape on the thermal pad.

Too hot, as you've already figured out.

The CPU was idling at approx. 60c in idle Windows environment. The
heatsink fasteners appear to be engaged correctly, but it's difficult
to be sure since the board flexes so much as they're pushed in. After
pushing some more and aligning heat sink screws perpendicular to the
heat sink, the CPU temp now idles at approx 50c, about 63c immediately
after bootup.

Still a bit warm. Did you remove the clear plastic tape from the thermal
interface pad before installing the heat sink?

My tower only has one fan, so I left the top off for the time being.

Where and in what direction is it blowing?

How can I get the temperature down to normal?

Getting the heat sink properly installed is a good first step.

Also, Intel says that
the pre-applied thermal interface material(TIM) on the heatsink must
be replaced if the heatsink is removed?

That's a statement you've made, not a question.

Will that be difficult
considering how hot the processor's been running?

No. Scrape it off with the edge of an old plastic library card (or
whatever card) or similar and polish it up with a bit of isopropyl
alcohol or acetone. Search this group's archives on google for a lot of
advice and procedures on this topic.

Can Arctic Slver be
used in conjunction with the TIM?

Now. Scrape it off and start clean with the arctic silver.

Any help would be greatly appreciated.

I'm going to die rather sooner than I'd like. I tried to protect my
neighbours from crime, and became the victim of it. To jump to the end
of the story, as a result of this I need a bone marrow transplant. Many
people around the world are waiting for a marrow transplant, too. Please
volunteer to be a marrow donor:
