Do you mean that you've got a BIOS that, as a default, sets your fans to be automatically regulated and that SF is no longer able to set their speeds?
Which hardware have you got?
You might add here a SEND REPORT or send it directly to me.

hmm... Im guessing that my bios that does that?? but the prog looses full speed control over all fans..
I have an Asus A7V8X-X...
(if possible with my mobo,when i set my pc to suspend for some reason it keeps all the fans running still.. would anyone be able to answer that?)

The main SpeedFan window has got a small text box which contains these info :-)

I can't find your SEND REPORT. Perhaps you entered an invalid email address.
Anyway: your hardware monitoring chip is one of those that are initialized by SpeedFan. I will reinitialize it after RESUME.

I have exactly the same problem (same motherboard, Windows 2000) when resuming from hibernate or standby mode, speedfan doesn't control the speeds anymore. I still acts as if it does but nothing happens.

I'm working on this issue. The problem is that the BIOS is completely resetting the registers in the hardware monitoring chip. I need to rewrite some code to be able to reapply changes to the chip after resume.

I'm working on this issue.
Would you like to try the latest beta?

Yeah, I did, I already sent you a "Send report". It doesn't seem to work. The whole setting thing has a really strange bahaviour. For example: if I set PWM1 to software controlled, the fan speed goes down but PWM1 remains unchanged to ON/OFF. If I then set PWM2 to Software Controlled and then back to ON/OFF it gets set to "Smart Guardian". If I then click on PWM1 again, the speed goes up again and so on... can't really see the logic. Also, as I wrote in the report, after coming back from resume I can't set PWM2 to Software Controlled anymore. Then if I play with it a little, I can again but nothing happens. Eventually after setting all of them do different values, the speed goes down but immediately goes up again. It's all really strange...

There was an error when setting the registers.
A new beta is in your mailbox :-)
