3.5v on the -5 rail?

[Lakitu]

I have just installed my Enermax Noisetaker 485w, and everything is going great, except that the program I use to check temps and whatever else(ABITEQ) says that the -5 rail is running at 3.5v, and it makes my case speaker beap and it is highlighted in red. Any ideas what's going on?

Alright, I looked at my old PSU's motherboard connector, and the reason I'm getting 3.5v on the -5 line is because the noisetaker does not have a -5 wire on it! On the old PSU, it's a white color wire(the only one that's white), and the new one doesn't have that, it's just an empty hole there. I can take pics of needed, but I think people should understand what I'm talking about. Is this -5 wire needed, if it is not included? The instruction manual says it's ATX, and should work with 20 pin, but WTF? I went under the FAQ topic and went to the motherboard connector part and went to the supplied site, there it had a picture of the motherboard connector and said what each wire did, that's how I found out which wire I am missing, it's pin 18's wire. So..am I ok without having the -5 wire or not? Is it supposed to be like this? Any help = appreciated.
