Reading CPU Temperature (including each core temperature) without third party tools
-
I'm trying to make a program that reads the temperature from the cpu and then sends it to my arduino duemilanove, where I have a 4 digit 7-segment display. I've been searching for a while but found nothing about reading the temperature from cpu's DTS (Digital Thermal Sensors). I don't want to use CoreTemp or any other related tool. EDIT: By the way, I have a asus n61jq laptop with intel core i7 720QM

I'm trying to use __readmsr() intrinsic function to get the temperature, but it keeps giving this error: "Unhandled exception at 0x000000013fd81009 in test.exe: 0xC0000096: Privileged instruction." It seems that rdmsr instruction must be executed in privileged mode. EDIT: Is there any way of switching from user-mode to kernel-mode instead of making a driver?

It could help but I never worked with WMI, so I will need a example of its use. I've just downloaded the WDK and I will try to read the temperature by making a driver. This could be fun! :D

Using WMI will be much simpler than doing a driver - search CP and you'll find lots of articles on WMI such as Making WMI Queries In C++[^] Judy
