dont know if this is old news but here goes.
To get Coretemp working in Vista X64 without having to disable Driver Signing from boot every single time try this:
Download the CoreTemp hack from here -> http://http://forums.erodov.com/local_links.php?catid=18
Extract 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
