So Who Do I believe? And why aren't Temps Accurate no matter what OS you are running.

Power management will differ between Windows and Linux, meaning you will indeed see different temperatures. It also depends on system load. So you believe whatever operating system is currently in control of the hardware, as that is the one doing the power management (decreasing speed of CPUs as load permits it, powering down unused devices, controlling the fans, and so on). Your BIOS will also have temperature information, again then using its own power management which will differ again from how Windows and Linux do it.

With either one of those variances your temperatures are good.

However, whatever sensors-related software you run (bios, windows, linux...) the real hardware (temp/fan) sensors are basically not accurate. The most reliable are the cpu and hdd internal temp sensors.

Thanks for the info.
