-12v Reading?

[markperkin]

Hello,
Sorry to ask such a stupid question. I have googled and just can't seem to find anything. On HW Monitor what sort of readings should i be getting for -12v?

The -12V rail is pretty much obsolete now and is only kept on to provide backward compatibility with older hardware. Some older types of serial port circuits required both -12V and +12V voltages, but since almost no one except industrial users use serial ports anymore you as a typical home user can pretty much disregard this rail.

When there's no load on that rail you may get some odd readings that you can just ignore.

Well mine is reading at around -6v area, is that not normal?

As I've said it's an odd reading that you can just ignore if your motherboard doesn't have any RS-232 serial ports.
