My Astral 5090 OC irregularly reports 0 rpm on the side fan speed monitor and at the same time the physical side fan speed spins at max.
The fan is out of sync with the temperature/GPU load and spins around at max speed making a terrible noise.
Is this an initial defect or failure of the HW? Please help.
[change from correct operation to abnormal operation]
- During fan rotation, GPU Tweak III starts reporting that the fan speed is at 0 rpm.
- At the same time, the physical fan accelerates and continues to spin at its maximum speed.
[Change from Abnormal to Correct Operation]
- During fan rotation, GPU Tweak III will begin to report if the fan speed is at a value other than 0 rpm.
- At the same time, the physical fan will slow down to synchronize with the report.
[Miscellaneous]
- When [0db fan] is on and at low load/temperatures, the fan stops correctly.
- When [0db fan] is on and at high load/temperature, the fan needs to spin up and the abnormal behavior described above occurs.
- When the [0db fan] is off, the fan needs to rotate and an error occurs.
- Normal > Abnormal operation occurs at high loads with high probability, but also at no load with low probability.
- Abnormal and normal switching occurs randomly over a period of minutes to hours.
- Referring to another article, I changed from [12VHPWR included with PSU ] to [12VHPWR-4x8-pin adapter included with GPU ], but the abnormal operation was not fixed.
- Referring to another article, I tried uninstalling GPU Tweak III and HW Monitor, but the abnormal operation was not fixed.
[Moive and ScreenShot]
Be careful with the volume! The GPU fan noise will be very loud.
