From the looks of those numbers, the Aux temp must be your CPU. You can tell for sure by firing up Prime95 while monitoring the temps. The CPU temp will rise very quickly (especially since you have a Prescott). It's not that unusual for sensor monitoring programs to misidentify which temperature is associated with what device.

Regarding thermal throttling, there's a good article on the subject here where some Russians tested the throttling on both a Northwood and Prescott. In both cases, it didn't kick in until the mid 70's C. Your throttling should be enabled unless your BIOS allows it to be disabled and you changed it. It's always enabled by default.

By the way, 61C for a 3.0GHz Prescott while loaded ain't great but it's not terrible. Mid 50's to 60 are pretty common. All BIOSes should read the same temperature from the CPU temp diode but some have bugs so you can't always trust the reported temperatures. The BIOS actually does a calculation to get the temperature so they don't always report it correctly. If it's really 60C then it's not something to get crazed about. You could probably drop it quite a bit by putting a big-time heatsink on it. But 60C with a conventional heatsink isn't alarming (it's not great either

).
