That's normal operation for Core2Quads. They're not like later quad cores. With Core2Quad the first core runs the scheduler and splits up tasks to the other cores so it always runs hotter than all other cores by design. Later starting with the first i7's on LGA1366 the scheduler was re-designed and we didn't have that issue anymore. Core2quad was mostly an after-thought after Core2duo and they just slapped two dual core DIE's on a chip and kind of hacked it together. The first i7's were completely redesigned from the ground up as a purpose-built quad core.
