Windows Driver - Read CPU Temperature - Dual core

I need to read the CPU temperature of an Intel x86_64 processor. For that I am planning to write a Windows kernel mode driver that can make use of the call __readdmsr 'asm' command.

But I am not sure on how to select the core for which the readmsr command is to be applied.

Can you please help me with this?

It looks like you could use KeSetSystemAffinityThread for that. Restrict the thread with 'rdmsr` to the processor you want to check.
