Windows 7: Dual SpeedFan +5 Readings

Dual SpeedFan +5 Readings

Maybe it has always been there, but I don't remember it being so. As seen in the screenshot, SF shows two different +5 voltages, one normal and one high. There is the option to display - 5 voltage, but I have that disabled. My main concern is the high +5 voltage, since it is beyond the 10% tolerance level.

Checking the Configure tab show identical information for both values...except the outputs. The question is whether this actually indicates a problem with my power supply. The question is significant, since I intend to use this PS in my new build in the near future.

These values normally follow a pattern when displayed. The top +5v is almost certainly the +5v display I believe the second one ( I have marked it ) is what is marked as Standby on my display (see pic )
I do not know what the tolerances are for this tho

Hmm, that answer most of my question. The only thing left is how significant the second value is, and how much tolerance it has? Curiously, if both values are the same in both of your screenshots, I wonder why they have such different voltages?

The left screenshot is yours for reference
I should have marked it

Oh! Now I understand. I'm not familiar with the program in your right screenshot, do you not use SF? I'm just wondering if the SF is reading it properly?

No, sorry I used to but eventually gave it up for Everest
My program is AIDA64 formerly Everest
I wouldn't rule out a bad reading by SF have you tried contacting the SF support? I can only say good things about Alfredo Milani Comparetti he went out of his way to help me when I had problems.

Huh! I installed the trial verison of Aida64, and it doesn't give any value for standby:

EDIT: I just checked the label on my PS, and it does have two 5v outputs, and the second is suffixed vsb, which I assume means standby, so I wonder why Aida64 doesn't show it? Exactly what is the standby voltage for...the failure of the normal 5v output? If so, then that extra voltage may not be important until a primary voltage failure occurs, and then the extra voltage could be damaging.

I do not know why it doesn't show up in Aida But it does seem to confirm that the +5v is OK
The Standby 5v as I understand it is used for your Power switch, keyboard and mouse and possibly USB ports

I just Googled the definition of the 5v standby, and it isn't what I thought, it is the power going to the system, when the power is otherwise off. I checked the hardware monitor in the BIOS, but it doesn't show anything for the standby power either. In one thread, it was recommended to check it with a DVM, but where could that be measured, and if SF is accurate, is that reading something to be concerned about?

I cannot say mate but I am sure that I read somewhere that it should be OK as long as it is under 6.5v. You really need to ask someone else with more experience in these things

I just asked for someone else to have a look here .)
