Intel Pentium M 1.8 running @ 67 degrees celcius

Hi Guys

I have a MSI M510c (very nice notebook).

I had the 1.6 processor which ran at roughly 45 d/c when idling, when being utlised it could go up to as high as 69 d/c.

I upgraded my MSI and now have a 1.8ghz and it runs very nice and smooth - only thing is the cpu runs quite hot - 65 ish when idling (if I unplug the charger it runs at 52 d/c odd).

How concerned should I be?

The fact the it runs cooler when unplugged makes sense because of the default setting to lower the clock speed. But 65 sounds high for idling. What are your SpeedStep settings? Is it idling @ 1.8 GHz?

Thanks for the reply epp_b, excuse my ignorance but what is "SpeedStep", where do I check the settings?

Yeah that was what I would of thought.

How do you mean? The processor is idling and it is running at 1.8ghz as far as I know, I havent under/over clocked it or anything if that is what you mean...

Did you put in the 1.8 processor yourself? If you did, did you use some Arctic Silver? You may want to put some on there. Also P-M's are fine up to 100 C so its really not much to worry about. Also make sure your fans and vents are clear of dust and dirt.

What he means is when to computer is unplugged from the wall, the CPU clock speed automatically decreases itself mainly to extend battery life during operation. While plugged in and recieving unlimited power from the wall, the computer will automatically replace itself at the current clock speed... ie 1.8 ghz. When running on battery, the PC may drop down to 800mhz or somthing. This is natural. If you suspect you are getting high cpu temps, make sure vents are not clogged. Either by a pant leg or somthing like a piece of paper or even dust. I know on my old xps, I blew the fans with compressed air to clean vents, and my temp went down 3-4 degrees C. Also, programs running in background may make the cpu work harder and therefore your temp may rise.

I need to type faster...lol

Nope, the guys I bought the notebook from did, its brand new - not even a week old yet.

100 C, shit I didnt know that - well I wouldnt want mine running that hot anyways.

When just working it sits at around 63 C and when burning it @ 100% CPU as well as copying files across network etc... it goes up to 76 C. You think I got nothing to worry about?

The vents definitely arent clogged or anything, sitting here on a desk in a moderately cool room.

I don't think you have too much to worry about, but don't quote me on the 100 C either it's just what I read on these forums (it seems accurate to me though). Besides that, almost all computers shut down if the processor starts to get too hot. You should probably try to find out about the Arctic Silver anyway.

my P4 is not supposed to go higher than 78C so I would be worried about a computer going at 76C. I would call the reseller and tell them about this problem.

P4 and PM have completely different architectures and thermal properties, but yeah, talk to your reseller.

Yeah I've heard max is 100 celsius for Pentium M. I used to have a MSI M510c, and with a Dothan I would get around 42 idling, 70 when working. I think the main thing is the cooling structure of the notebook itself. Perhaps other M510C owners can chime in?
