Yes, that is extremely hot (for any CPU!) ... irrespective of ambient temperature, controlled overclock or whatever.
I'm running a 2.8C (30-capper) currently, showing 42C as I type at an ambient temperature of 22C using a stock Intel heatsink & fan.
Things to do ...
If it's been like this since the last time it was assembled you would do well to check that the heatsink is properly fitted (mechanically & thermally OK).
Check the CPU fan speed vs original spec (use the PC health check - or whatever your BIOS calls it screen to double-check temperature & CPU fan speed). Or Sandra or MBM or your motherboard manufacturers' equivalent monitoring software.
Clean out all the dust from ... everywhere! Scour the web for answers & DIY/DIdon't advice on how to do this.
Check for failed or failing inlet/exahust fans (failing fans are mechanically noisy and feel hot to the touch in the centre after they have been switched off).
If in doubt, plan ahead now! Get ready to take a day off, dissassemble everything. Dust everything off [B]carefully[/B] & re-assemble. You'll need the right tools, replacement thermal material for the heatsink and possibly replacements for failed/failing parts
Frankly, if I were running that temperature on my CPU I would switch it off immediately & take it to my local PC repair shop before it went POP.

According to what I've read, the P4 will throttle down if it gets too hot. I'm more worried about the performance of my machine. Am I incorrect in thinking that the excessive CPU heat won't damage my machine?

Just a follow up...
Wow! So, I opened up the case and examined the CPU fan and heatsink closely. As it turns out, the tops of the fins on the heatsink were covered in a layer of thick dust and grime! So, basically, the fan on the heatsink was cooling off the dust and grime.
I felt like an archeologist brushing off an artifact in a tomb when I started cleaning the layer of dust with a Q-tip.
The results... My CPU is, to my amazement, running roughly 40 degrees cooler. 40 degrees! So, now, games and other graphics applications are running not just noticeably faster, but significantly faster.
I never imagined that dust could affect my CPU so drastically. Chip manufacturers should probably make more of an effort to emphasize the importance of dust removal from cooling components. Then again, maybe I'm just dense.
Anyway, thanks for the help.

hehe, great you solved your problem. Let me just quote from the FAQ about too high CPU temperature, here on this site:
"The first step is to check the CPU fan, the air intakes of your case, and all case fans for accumulated dust. With PCs that have been running for many months, and thus have become dusty on the inside, removing dust alone can bring down temperatures drastically"

You're welcome, JT2N.
For the record;-
a) it's not uncommon to "tank out" a server room itself with filter material. That's right ... filter the whole room from outside dust, then filter the servers!
b) Never, never put a filter on the exhaust fan. That's never, OK?
c) On my main PC I've blocked up all the extraneous holes punched into the case with packing tape (on the inside of the chassis). Yep, that's all 6 sides ... and the corners!
d) the USB ports can suck in dust, so I have plugged them.
e) I maintain negative air pressure inside my PC and manage airflow as as follows. The case is kept in my desk where I have separated the front airflow of the case the back.In order to add extra capacity for airflow from the front/outside I've converted two 5 1/4 drive bays to become intakes ... filtered of course!
If you take a look at the stuff I have for sale on Ebay, my userid is "1jupiterway", you'll find all you need to do the same & more!

i have the same problem too
i have a desktop p4 proc with a fan that got broken. i changed the fan for a new intel one but the temperature has been around 70 since then. the systemalways shuts down after like 5 minutes and idont know what to do. note i have changed the fan 3 times!
