Actually there is a way to make Coretemp work in Vista X64 without having to disable driver signing requirement.

Download this file: http://downloads.erodov.com/c/o/r/co...4-VistaX64.zip

xtract this to your favorite directory (say C:\CoreTemp)

Just make sure before you start the actuall "CoreTemp.exe", you run "coretemp-startup.bat"

This will load the CoreTemp driver and thus will allow CoreTemp to function normally without having to disable driver signing

Tell me if this works.
