I've recently been turned on to CPUID Hardware Monitor. I've learned that PC Probe II is unreliable and in general, I've been noticing very unliable data from CPUTIN which is what PC Probe II shows. With CPUID Hardware monitor running, I've been able to watch the core temperatures, which appear to be much more reliable info.
One reason I believe it's unreliable to read the CPUTIN, is I'll turn on PC probe one time, see the temp at 32C, then turn on HW monitor and both will jump 10C, and if I open them in the reverse order, I might see the same thing. Sometimes the temps are lower than the cores, sometimes much higher. Anyways, I'm not paying much attention to that info anymore.
