[Solved] Physical core layout I5 750 ?

I was wondering if anyone knew and or had a picture of the physical layout of the 4 cores on a I5 750 chip. I'm curious if the four cores are at each corner like a square -
12
34

for example, or if the cores are
1234

The reason I ask is, on idle temps consistently at different idle no load frequencies my # 3
core is 4 degrees Celsius higher, something like this
31 30 36 29

This all leads to me wondering if the load or seating of the factory hsf is not on correctly or ideally perfect. I had trouble seating one corner and started the process over twice. Mainly to cure curiosity , I don't think I have a problem.

Thank You..............
