They are +V, -V, and RPM sensor.
Ok Gary now I find that in the BIOS I take it or is a program I download? as I haven't had chance to look into it yet.

It's part of the BIOS for AMD system boards. It will be listed under some sub-menus, or a sub under one of them.

It can be any brand board, I meant a board that uses an AMD CPU.

Something that may explain the temperature difference on your cores. That's a Brisbane core processor and AMD always had trouble with reading the temps off of a Brisbane CPU. They're never right, or if they are they never agree. I have a Brisbane 5400+ in my HTPC and the two cores aren't even remotely close in temps. Sometimes they differ as much as 20 degrees.

It's a known bug and it's nothing to worry about unless you're overclocking.

Actually Melon if I remember right it was a Brisbane as I did look that CPU on CPU World and was surprise at what a low temp range it could only run to.
My mate did say it was touching base with 65C at times and the lettering was red when he opened it up and had a room pedestal fan blown in . The difference then as now is 10C and from the few bits I did like the cleaning, compound, and adding that extra fan at the rear it was running 28C and 37C when he picked it last night (Ambient temp 32C as we are in a heatwave at the moment) so I am guessing those steps are not too bad. My last alternative is to add yet another fan to the vented side (no fixings so will have to improvise) but as of now things are not to bad considering it is going to get hotter they tell us

From the Speccy picture in post #1 your 3.3V is only 1.76V.
That is way to low.
Should be around 3.290V or a little higher with the system up and running.

Ok Jack I will get it back and flip in a spare PSU as that one you will have seen is a rather sad 228 watt model.
