    For the built-in video card I almost always writes minus. I thought it was a bug.

    Emerson make industrial PC's with AMD CPU's that are rated -40 to 70 deg C ambient. This sort of temperature range is considered extended environmental conditions so not super common for industrial applications but they do exist.

    I'm a little surprised negatives weren't working, but moreso, I'm surprised about how many people think it's weird to encounter negatives. While I wouldn't say it's common for a CPU to report such temperatures, even a typical home user might encounter it. For example they were to turn on a laptop that was left in sub-freezing conditions (like being left inside a car) for a while.
    This is probably because firmware authors often encode errors as -1 or -99 or something like this.

    Doesn't look like it's going too smoothly with this patch:

    This was introduced with commit aef17ca12719 ("hwmon: (k10temp) Only apply
    temperature offset if result is positive"). This patch would effecively
    revert that change. Given the reason for introducing it I am not convinced
    that it is a good idea to unconditionally revert it.​

    Does this mean the beginning of the "extreme OC era" on Linux?

    Given that 0 deg C is just 32 degrees a lot of places other than Antarctica get that cold! Heck 32 degrees is mild in a lot of parts of the world!
    <0°C ambient temperature is not sustained for too long inside a PC.
