Also, I think my fan might be broken or something. I can see and hear it spinning but when i put my hand next to the only exhaust vent, i can barely (i mean really barely) feel air being pushed out. I haven't opened it up yet, but could my heating problems be attributed to dust? Should I send it in for repair? I was thinking about trying arctic silver 5 on it. Any suggestions?
Pentium M systems (that I have seen) have a normal (idle) operating temperature of 50C or more. I believe stage 1 active cooling (the fan gets turned on) is supposed to kick in at 66C by intel spec, though the maufacturer could change this*. Stage 2 active cooling (fan goes to high speed) at 73C. Throttling CPU frequency back at 92C and the intel spec has the system shut down at 100C.
It important to remember that your notebooks fan still isn't supposed to kick in until the specified temps are reached and the processor isn't in any danger at those temps. Because the CPU is actively monitored for temperature the system doesn't even try to improve cooling until it is needed. More important is the temperature of the HDD which can suffer increased odds of mechanical failure if force to run at higher temps for extended periods of time. The best way to avoid that is to keep the notebook in the shade, airconditioned, and on a proper work surface.
*anecdote My TM3200's fan turns on (low fan speed) at ~50C(CPU) when using AC power and at ~60C under battery power. The major system difference here is the r9700 GPU usually runs at 450MHz under AC and 100MHz under battery.
Oh and I'm using Mobile Meter
for monitoring things.
