SpeedFan 4.40

[seekermeister]

I've been using SF for quite some time, even though it seems to never detect everything that it should, but usually once it has been installed, it generally continue detecting whatever it has found, unless there is some kind of hardware problem. However, at the last reboot it popped a dialog showing what it had detected, which did not include any of my 3 harddrives. Over time, one of the fans also disappeared. Somehow, with the number is disappearances, a hardware problem seems unlikely, unless it is the motherboard itself.

Here is the log data that I copied from SF:

I don't know if this means anything more to someone else than to me, but all of those lines talking about WRITE ONLY seems odd, is there a way to tie these to anything specific?

This might seem like a silly question. Are you actually using SpeedFan to control anything? I've tried it a few times for monitoring. The stability seemed to fluctuate quite a bit from build to build and from PC to PC.

I find Core Temp much more stable for monitoring temp and cpu load. I am only running stock, no overclock. I don't think I can push this PC to overheat. Only thing is the way they have the fans speed up, then slow down, it sounds like a hurricane howling outside. Spooky.

Control...no. I only use it for monitoring.

In that case I'd take a look at Core Temp. It's pretty big on AMD support. But make sure your CPU is in the list.

Here's the home page:
Core Temp

I'm not having a problem reading the core temp, it is the values for the harddrives and fans that are a problem. Googling, it appears that the devices connected via the SMBus should be both read and write, therefore since SF can't read them, this is the root of the problem. The question remains is what is actually preventing them from being read.

Odd, I just logged in as administrator, and SF is seeing all of the harddrives. The only thing missing is one of the fans. I wonder why it works this way and not when logged in under my user account, which has admin privileges?
