seekermeister, I think speedfan reads different chipsets differently. I'm not sure why. I used to use it but would get different readings on different chipsets. I installed it on this p67 chipset and it wouldn't read hardly anything and what it did read was wrong. It showed my +12V at 7.6V. If that was true, the system wouldn't even post. On my AMD890 system I got different readings from SF and hardware monitor.
I just took pooch's suggestion, and sent an enquiry to Alfredo about this (hope that he's not having a bad day, or is on vacation). I do understand that SF is far from perfect, but I continue using it primarily because it is the only monitor that I'm aware of that can provide a continous reading in the System Tray icon...of course, being free doesn't hurt either.
I just tried it, primarily because I thought that you were saying that it would display System Tray readings, but if it does, I didn't find that option. It does not display anything for + 5vsb either. The only thing that I particularly like about it, is that it shows both the system and CPU temps as cooler than SF does, but it doesn't show temps for my hard drives or graphics card.
It obviously depends on who made or how the motherboard is designed with regards to sensor readings and the software reading it. I note that I don't have the +5 standby readings that pooch shows in his AIDA reading, yet I do have two +5 voltage readings in Speedfan
And we're (pooch and I) using the same version of AIDA64 - 1.70.1400.
pooch......
sygnus21,
Your +12v and -5v reading in SF are obviously wrong. -5 doesn't surprise me, because it doesn't work for me either, and I have it disabled, but +12v does, and that is important to monitor. Curious that your +5vsb also seems out of whack, but in the opposite direction of mine.
A 5v standby is common to most electronics, like a TV. It is what keeps the set ready to receive the remote signal, or send the power on command when the power button is pressed. It will also keep the clock time in a TV.
The voltage is not a run voltage, that is, it isn't sent to CPU or other chipsets to maintain operation. It is just there to keep the PC ready for the press of the power button, and possibly for USB port power as mentioned. There is likely a 5v voltage regulator specifically tasked to provide this 5v standby, and the voltage could likely range from approx. 3.9v to 7.5V. I wouldn't be concerned. A Guy
I haven't investigated it as I typically don't use Speedfan. I just installed it to see what you were looking at.
To be honest I never really understood Speedfan and all it's workings thus when I did use it I only used it for it's temp reading ability but found that Core Temp or Real Temp was just as useful for me, and less cluttered.
Anyway AIDA64 (formally Everest) gives me everything I need for sensor monitoring/readings.
As for the readings being off, well that was your complaint too :)
