CPU temps

[Big Black Stilo]

im using a Dell 1750 laptop with a Pentium(R) Dual-Core CPU T4200 @ 2.00GHz. its not clocked, its standard spec.

Recently the laptop was getting hot which i put down to a failed battery (10 mins to charge, 5 to discharge that kind of failed). i have the new battery in, which is cool even when charging, but the CPU and memory area seem to be still hot.

I have downloaded speedfan4.46 and it displays the following temps

HD0
Temp1
Core 0
Core 1

now, i know HD is hard disc, and i know Core 0 & Core 1 are the CPU, but what is Temp1? this temperature hovers between 41 and 56, anything over 50 has a flame next to it and is often a few degrees higher than the cores.

anyone know?

reason for asking, often the fan kicks in at 56c but sometimes its reaching 70c. also what is the max temp for this cpu?

Core 0+1 are sensors built into the CPU itself, Temp1 is probably a sensor on the motherboard underneath the CPU, possibly a GPU sensor.

See here for approx operating temperatures - http://www.pantherproducts.co.uk/index.php?pageid=CPUtemperatures

i think Temp1 maybe ACPI temperature (power supply)

only problem is, new battery is only 4 hours into its 14 hour first charge so i cant disconnect.

Core0 and Core1 never get above 50c

as a quick test, blowing into the CPU fan drops the temp to 32c on each core, but Temp1 doesnt drop, nor does HD0

Would recommend you download CPUID HWMonitor, works better than speedfan IMO and has an easier interface

Also the max temp for your CPU is a toasty 105C, although if it were getting anywhere near that I'd be worried.
