First OC going well but...

Thanks to graysky for the awesome tut about OCing!

I'm running a Q6600 (B3) at 3ghz and everything seems to be OK, except for the fact that my 4 cores run at very different temps.

Core 0 and 1 run at around 49C while 2 and 3 run at around 43C idle, and the same difference in temps at full load. Is this due to the HS contact? I'm extremely hesitant on lapping my CPU, but if I get bold I'll do it.

If I understand correctly this is the core layout:

01
23

So am I looking at my case from the side, with the front of the case on my right?

This is normal. Core0 is used first while Core1 is usually at idle or used very little until you use a app that can stress both cores. (this applies to quads) as you go down from core0-1-2-3 they are used less and less with core0 taking most of the processes.

When all cores are maxed to 100% it's not uncommon to see slight variance in temp between cores.
