So here is what I came up with using RealTemp T|I. I ran Prime95 blend mode for just under 4 hours. Please see the attached image.

Anyone care to comment on these temps? Ambient air in the room is 24 C.

System is:
i5-3570K stock default clocked 3.4 GHz with 3.8 GHz Turbo
Cooler Master Hyper 212 Evo with one fan in push configuration
Gigabyte GA-Z77X-UP4 TH Motherboard
Corsair Vengeance 8 GB DDR3 @ 1600 MHz XMP Profile
EVGA GTX 260 Graphics Card

The case is an old Thermaltake Damier Xaser V with 3 intake fans (Front, Top and Side), 1 internal blowing toward RAM from empty 5.25" bays, and 1 rear exhaust fan. The fans are not running anywhere near their max rpms. I have them set where the noise is not too loud.

I had attempted a mild overclock (4.4 GHz) using just the Turbo multiplier and 1.20 V. Last night I made it crash when I ran Handbrake for the first time. I realized then that it was no where near stable. Can anyone suggest a proper guide, thread, etc. for learning how to overclock my setup. I had gotten really good with my Q6600 G0 just before I bought this new chip. Now I feel like I have to relearn my whole BIOS.

Thanks again unclewebb for your explanation of the sensors and the purpose of them. I appreciate you taking the time to make me feel more comfortable with Ivy Bridge.
