Your software is wrong...and, so is that 120C figure. You use a figure called Tj max to set up a program like that. I would say that you are off a good 15-25C. Now, that being the case, you are still experiencing shutdown. That temp IS the Tj max...you might actually be the first guy ever to shut one down. I would suggest that your HSF is probably not seated properly or you put too much cosmic goo on it...or, gasp, you used the Intel crap. Get Arctic Silver 5, or Ceramique, or Shin Etsu. Second, this HSF itself sounds lame. Get a Zalman. Also, turn off smart fan...and run your CPU cooler flat out. You might also want to consider some decent case fans. I have a Q9450 o/c'd to 2.84, with an ASUS Triton 79 HSF, plus a Scythe Ultra Kaze 120mm (Great fan, but loud as hell. I have never seen a temp above 62C...and that was with my room A/C off, and running Folding@Home and World Community Grid/BOINC both at 100%. My PRIME 95 numbers also peak at around 62C. But, remember, the current temp software is not exact, so your absolute temp. can be way off. The only figure you need is the distance to Tj max. Also, forget about the CPU reading in the BIOS, that is NOT a core reading...and temp. accuracy fluctuates wildly when going from 0-100%. Still, by any standards, those temps are massively high...even if they are a bit off. And remember, sticking sensors are a problem with some of the earlier 45nm chips. Good luck.

Most chips would be irreversibly damaged after 90 C and not boot back up. Does the temperature ever change from 120? Does it shut itself off due to temperature issues? Is the chip itself contorted or discolored? Make sure your heatsink has enough (but not too much - don't want to insulate with it) thermal paste. About a pea size should do. Even and tightly attached heat sink should be enough with working fans to cool you down. I have a Q9450 overclocked from 2.6 to 3.4 even, and with an aftermarket CoolerMaster it maxes out a 70 C per core, 64 C for the total processor. Sounds like a faulty sensor to me.
