When you think about it, 3.0 GHz and 3.2 GHz are more or less the same; you're talking about <7 % increase which isn't worth it in my book if it puts your temps over the redline... then again, if you don't care about keeping it for a long time, f*ck it, clock it up to 3.6 GHz if you're stable and run the vcore as high as you need to do it.
Intel's spec of 62C refers to the Tcase temperature not the Tjunction temp. The temperature you're quoting for the cores is Tjunction.
Tcase is measured at the center of the IHS, right between the two cores and is always lower than the core temps (Tjunction).
Add 15C to the CPU output temp in SpeedFan and that is your Tcase temp (same goes for your temp in the BIOS). Keep this temperature below 62C and your golden... according to Intel.
Temperature limits vary from person to person, some are willing to push it a little higher while others tend to be more conservative. 62C for the CORE temperature is definitely ok, hell my CORE temp with to stock heatsink and stock frequency was 65C!!
I've found some pretty good posts on the topic, unfortunately they're bookmarked on my XP install, I'll be back....
EDIT: well I can't find those links, I guess I didn't bookmark them and I can't seem to find them in my history. I'll keep looking though, I'm sure I'll stumble across them at some point.
