|Summary||0002321: Problems configuring ASRock Z77 Extreme 4: Missing Fan (RPM reporting), Missing Speed (RPM control), initialization error|
|Description||Please, see attached file for the table and notes I created configuring the motherboard to be controlled by SpeedFan. My intent is to use 3 x 3-pin 120 mm fans (Scythe SilentTyphoon) attached to the water cooling system to cool the motherboard. Since fans are 3-pins and do not support PWM control, I need 3-pin heads on the motherboards that report RPM and support speed control via voltage. To my surprise I have found only 1 from 6 available heads satisfying these conditions. |
If you look at the attached table, you can see that CPU_FAN2 header almost satisfies the requirements, but unfortunately it is not detected in the "Fans" tab in SpeedFan thus does not have its speed reported by SpeedFan. It can be controlled via a "CPU" sensor in "Speeds" tab. "CPU" sensor seem to be controlling both CPU_FAN1 (via PWM) and CPU_FAN2 (via Voltage). Since the speed of the fan is reported by both UEFI BIOS and ASRock Extreme Tuning utility that came with the MB and runs in Windows, I assume this to be a bug in SpeedFan's sensor detection logic.
I have already sent a report via Info/Send Report but decided to also open an issue for better tracking. If more data is needed, I would be happy to provide it.
Initialization of the SpeedFan produces a warning. Not sure if it is expected, but it does not look like a good thing.

|Did you send me a SEND REPORT from SpeedFan's INFO tab?|

Yes. It does not have this ticket number mentioned, but you can correlate using the e-mail <username>@gmail.com (where <username> is to be replaced with my user name in this bug tracking system).
Once we resolve the problem, I would be more than happy to share the configuration file for this (very popular) motherboard.
For convenience I also uploaded the debug.nfo from the SpeedFan directory to this thread. And I also copied the report generated by SpeedFan in Info tab to a report.txt which I also uploaded.
Thanks for responsiveness!
|I just wrote to Asrock. You might try too. I think there is a GPIO used to multiplex the input from the fan and without Asrock help I can do very little :-(|
|I would, given that I am their customer, but what exactly should I ask for? What do they need to provide to you/me in order to expose the RPM counter for the supposedly multiplexed (makes total sense) fan?|
Also what about CHA_FAN2? The one with 4 levels in the table. I confirmed that I can control 3-pin fan connected to it using ASRock Extreme Tuning Utility from within Windows, so it must be programmatically available. RPMs are reported by SpeedFan on Sensor="Aux 1 Fan".
Level 1 ~ 55%
Level 2 ~ 68%
Level 3 ~ 80%
Level 4 ~ 100% of the full fan RPM (and therefore voltage?)
Interestingly, what I observed by making longer observations is that the RPM from the fan connected to CPU_FAN2 seems to be reported via the same "CPU Fan" sensor as the one connected to CPU_FAN1. One reading by SpeedFan returns the RPM from CPU_FAN1 fan, the next one returns the RPM from CPU_FAN2, then they alternate back.
If both fans are connected and have different speed, the fan speed chart for this sensor looks like a saw alternating between heights corresponding to these speeds. If only one is connected and the other one is not, then it alternates between the speed of the connected fan and 0 RPM.
