Laptop Overheating

I was just using my laptop, it is a HP Pavilion DV4000 with a Celeron M chip at 1.4GHz (had it less than a year I believe). I run Gentoo, so I compile alot. I was compiling something earlier today, and all of the sudden I felt that my leg was burning a little and looked down at GKrellM and realized that my CPU temperature was 216F and blinking red, and immidiatly after that the computer shut down (I have it setup that way in GKrellM, although it's suppost to shut off at like 180 I believe). I've never before had many cooling problems with this, but latly... the past few weeks, it's seemed to run hotter than it used to, but has never gone past 200F before. I know that has got to be a very high processor temperature, and likly not to be healthy for the chip or the components surrounding it. Does anybody know what temperature these processors are designed to run at, why its stopped cooling as well, and what I can do to cool it off? Hopefully this hasn't damaged my chip... I'm using the computer right now and its seeming to run fine, and hanging at 151F and is almost idle so that seems too high. The fan seems to be working, but not spinning very fast. I am not overclocking or anything. Anybody know what could be wrong? Fan going bad or the heat sink came loose or something?

Have you tried blowing out the cpu section air vents with one of those compressed air cans?
May depend on the changes from base install to what you have done. Any records of this?

I havn't changed anything physically on this laptop sence it was bought just under a year ago. I just stripped Windows off and put Linux on and it worked fine stock, and ran Linux a long time before encountering these cooling issues.

Re: Laptop overheating

Check out /proc/acpi/thermal_zone/xxx, there should be some files in there.

What are your trip_points?

Check out /proc/acpi/fan ... there should be a couple (or more) directories.
On my laptop I can set the fan to high by "echo 0 > state" in the lowest number directory.

I manually setup my acpi scripts as per information in the Gentoo Wiki.

I was installing gentoo yesterday on my hp dv6000z with the default gentoo kernel, and at about 7 out of 17, my computer just turned off and it wouldn't turn on until I tried it about 20 minutes later, so I tried installing again and it didn't turn off or anything, but I shut the computer down, and this morning when I tried to turn it on, it wouldn't turn on. The circle around where you plug in the charger is lighting up, but it doesn't show the laptop is charging. I hope it starts working, because I spent 800 bucks on this laptop, and If it's broken then my parents are going to kill me.
