Mobile CPU too hot?

I have a dell 600m laptop. I recently installed speedfan, and noticed somthing quite shocking.



Is it normal for mobile CPUs to run as high as 65C? I have heard about incorrectly applied thermal interface compound on laptops in the past, is it possible that the same happened here?
 
My Dell Inspiron is getting onto a year old so is probably getting a bit dusty, but my cpu can reach 70C after 10 minutes of Prime. It idles from 32-45C (i don't think the temp sensor is great)

However I never really do a lot thats that stressful. . .

My CPU is a Pentium M 1.83ghz. .

I don't think 64 is that bad. . but others may have more info.
 
64F is not hot at all, actually, hell thats damn good. However, yours is reading 64C and depending on the processor...that might not be so bad, however, its a mobile, you should not be seeing anything higher than 50...maybe 55...unless its and Intel...then it MIGHT be higher, but i dont follow intel chips all that much.
 
Sorry, in my haste I seemed to have forgotten several vital bits of information. The processor is an Intel Pentium M 1.5 GHz. Also, I incorrectly wrote 65F in my above post (fixed), I meant to write 65C. This seems quite a bit hotter than my desktop processor, so I am slightly concerned about the temperatures. Does anyone know about the temperature limits of the Pentium M processors?

Also, yes. I have checked and my battery is not one of the ones that will spontaneously combust. ;)
 
Take out the HSF and apply some AS5. You'll most likely see a drop of over 10c

My MBP idles at 45c and loads at closer to 85c. Yonah 2.0ghz.

:eek: Wow, 85C. Can you fry eggs on that thing? :D

How hard is it to apply AS5 to the CPU?
 
Just find out where the cpu is located and take off the covering.. usually there are a couple screws holding the HSF in. Look also look for thermal pads. If there are thermal pads they can usually be taken off and AS5 can be directly applied to the heatstink.
 
You are going to see a large difference in your desktop temp verses your laptop temp for the simple reason that your laptop is a pentium and your desktop is an Athlon. I say that rather than Intel and AMD because, Intel now with theyre core 2s run cooler than most AMD chips currently out. However, Athlons are MUCH MUCH cooler than ANY pentium chip unless it is underclocked and undervolted, even the M processors.

You can definatly remove the HS and apply some AS5, that cant hurt anything, even if it doesnt have a heat spreader on it, you shouldnt have a problem.
 
Thanks for the info. I knew the P4 was a hot CPU, but I thought the Pentium M was different. I need to crack the laptop open anyways to install a new hard drive, so I suppose I can mess with processor at the same time.

i toke my hole damn laptop apart to find my damn cpu, when i did the heat sink is stuck on. so 2 more hours put the damn thing back together. * yes it still works *

Oh hell yeah. I'm sure I could. Keep in mind that was after I reapplied AS5. At the time I got an 8'c temp drop (91 down to 83) but I had to swap my motherboard, this one came in at 85'c Tri-Load, and Im too lazy to fix it.

**EDIT** Tri load = Orthos and RBTHDRBL under Windows.
 
wow, my old laptop made my hand red and if there was something plasic it would be very weak.

have you cleaned out the fans?
