what HFS are you running? i7's do run hot, cant go by old cpu's for looking at temps with i7. many seem to run 80c max, since it has a 100c tj, that would be a 20c buffer to TJ. though i dont like high temps my safe zone i keep mine at is mid 70's. the max it sees on a ninja hs is 75 during the day and at night i never see it go above 70c. that is at clocks in sig, so something doesnt seem right if your hitting that high for 3ghz. though i would suspect your running the stock sink but that may be wrong. since i have seen a few reporting 90c's on stock cooling at stock speeds...
