CPU cores are 10'c different using Cooler Master Hyper 212 Plus

Yeah they could have that much of a diff, seen it several times with older amd 64bit cpu's.
It's the cpu lid and the gunk they use for a tim that causes that.

In your instance, it would be the lid on your intel chip.
The only way you're gonna fix it is to remove that lid or work on improving the cooling in a diff way, like lapping the lid or heatsink.
Diff fans, better heatsink, etc.

If it doesn't give you any trouble then I wouldn't worry about it, I've only heard of one cpu failing because of this prob with the tim putty gunk between the lid and cpu.

Isn't your cpu supposed to have solder of some kind instead of the putty gunk that amd use though?
That would be kinda odd if they screwed that up...


Edit:
In your case it must be the heatsink though it seems...

I had something like this happen to me with a 920. I was using a Mega Shadow for Air Cooler and had 1 core with temps like you are talking about.

It was off by so much and started creating issues at higher OC's. So I ended up RMAing the CPU and the replacement worked just fine.
