ASUS P8Z77-V and Speedfan: No chip detected

post #1 of 9
Thread Starter 
Tried to use Speedfan to control fans on my new machine, installed Speed fan and couldn't find a chip that lets me control fan speed:
Did I do something wrong?

Maybe it's not supported. Afaik, Asus has great "Fan Xpert 2" application fo fan speed control, it's even improved from original Fan Xpert.

Yeah, except up till yesterday it had a bug which reset your fan profile each and everytime the computer is turned off / reset.
They've patched it today tho, with version 1.00.15

Maybe it is unsupported, wonder if any other ASUS Z77 owners are seeing the same thing

Yes, same thing here. SpeedFan ver. 4.46.

AFAIK : AISuite (FanXpert 2) is not showing core temperatures as CoreTemp,RealTemp etc. that's why I went for speedfan but now this.

"Totally separate sensors. Real temp reads what the CPU reports. That´╗┐ Asus software is reading a thermistor that likely sits under the processor and isn't the processor itself at all."

Run SpeedFan and leave it running for a while. Mine somehow got a second breath. Now it's showing everything as before. What a glitch smile.gif

SF is showing interesting CPU Core# idle temps - 12-12-16-17 but CPU is 34 , probably not compatible yet with 3770K.

Sorry to bump an old thread but I'm having the same problem.
Yesterday I installed speedfan and it worked and I could control the fans, but the next time I opened it, the chip was not detected. I haven't tried reinstalling it yet or leaving it on for a long time though.
Does anyone know if this is just a glitch in the software or what?

Wow.. literally just after I posted that I opened it again and can now control the fans...

I posted something on the Speedfan thread, maybe I should've post it here because I have the same motherboard, but the problem is slighly different : SF properly detects fans RPM and temps, but is unable to control fans speed.

Problem Solved !

Configure > Advanced > Nuvoton NTC6779D > all PWM modes set to "Manual" instead of "Smart Fan IV".

Now SpeedFan is working like a charm. ASUS Fan Xpert2 is really, really lame.
