Look like im no the only with this troubles...
I hope the R&D will apply what they will discover at this motherboard too.

Here a picture.
Fan 2 is CPU Fan and it's fine.

Fan 1 and 3 are Chasis Fan...from bios i get the same readings value.
Only if i set full speed the reading become right and show a correct rpm.

Forgot: If i set full manually full speed from bios,then save settings,re-enter bios...at full speed report correct value and not random number what change every second.

Hi,thanks for the reply :)

As fan reader i use SPeedFan,Asrock utility,Motherboard Monitor amd also from Bios,same result,swap between unrealistic rpm. (like 5000/12000 rpm swapping in less of 1 second..for example,random number at all) I ve also noted that,if from bios i set the 2 fans to full speed the value feedbaak rpm is correct for both fans.

The cpu 4 pin fan is fine.

Didnt use any splitter,2 chasis for 2 fans,i the F12 arctic im using spin right and work fine on othe rmb before i changed and updated with this.

I suspect too the chasis 4 pin pwm...are dumbor fake pin.
At least if cant autodetect cause its a "minor product" usually they put the bios setting.

On this motherboard instead ( Asrock Z97 Anniversary ) report high and low values ?�quickly changes randomy

If I set the fans at full speed manual shows the correct value too.

In other mb bios ther is the setting for switch control from pwm to dc...ther'isent here?

This ever happened to anyone? Any hint?

Thanks in advantage and sorry for my english :)


I have a different ASRock Z97 board than you do, a Z97 Extreme6, as well as other ASRock boards, a Z170 Extreme7+.

The Z97 Extreme6 board only has one four pin PWM chassis fan connector. I've used a few PWM fans on the four pin PWM Chassis fan header, and they all reported the correct fan speeds, with no absurd speeds shown.

The Z170 Extreme7+ board has four, four pin Chassis fan connectors, and this statement in the Specifications:

"All CPU/Chassis Fan Connectors can auto detect if 3-pin or 4-pin fan is in use."

The Z170 Extreme7+ board is more than twice the price of the Z97 Anniversary board, so has more features like this, that your board does not have. So all of your four pin Chassis fan connectors may not be true PWM fan connections.

You know that the fan speeds are never exactly the same speed, and change plus and minus a small amount every few seconds, right? A 2000 RPM maximum PWM fan on the CPU FAN1 connector shows a low speed of 811 RPM and a high speed of 861 RPM over a minute of time. Other slower fans show speeds between 635 RPM and 672 RPM, for example.

The pin on the board's fan connector for the fan's speed is the same pin for three and four pin fans, so that is not the problem. Also, I have used PWM fans on three pin chassis fan connectors, and the fans worked fine and reported the correct speeds.

If you run more than one program at the same time, that sometimes will cause bad fan speed data to be read by one or more of the programs.

What program or programs do you use to see the fan's speeds?
 
When the fan speeds are absurd, is that in the BIOS/UEFI, in Windows, or both?

I think you checked the two Arctic F12 fan connections on the board to be sure they are connected right and the wires are not broken, right?

You are not using any fan splitter cables with the two fans that show absurd speeds, right?

So no one get crazy rpm reading values from pwm fans chasis? :(
