Hey i just got a Galax gtx 1650 super ex 1 click oc twin fan.
All the monitoring apps, hwinfo, hwmonitor, gpu-z showing the fan RPM as 0.
It's listed as 40 percent and I can clearly see both fans spinning.
I used the xtreme tuner app and I am able to manually set fan speed to 100 percent but it seems the fan 1 setting in the app controls BOTH the fan speed, not independently.
The Fan2 setting doesn't do anything.
I can set fan curves and the fan speed percentage is correct.
Just that the RPM is always 0 in other apps, and there's no RPM indicator for their xtreme tuner app.
Does this mean this cheapest gtx 1650S doesn't use PWM fans and instead hook both twin fans to the same port ?
Here's my guess:
1. Yes both fan controlled together, same all the GPU I've encountered so far, and the slider will control both fan. I'm not sure whether that's via PWM or voltage.
2. Fan2 may be that extra fan port at the right end of the card (PCIE slot facing down), my Strix has it and I use it to control case fans.

3. The "other" app may be reporting data from the Fan2 header, that's why it is always 0. Only the Asus app can read the external fan data.
4. I have no explanation why Galax choose the non-default fan header as the primary.
