this is 1.5875 in bios though (as in setting) - at load its 1.528V (according to CPU-Z) so depending on what you are measuring my temps might not be that good 
is your E6600 an early one ? Mine seems to LOVE volts - yet not get that hot (relatively for the Vcore) - yet you read of peple with later ones, at 1.39V @ 60C +
