Problem with MSI RX5700 fans and sensors Issue with fan speed sensor or motor performance
I was experimenting with AI video upscaling and noticed my GPU heating up significantly (85°C and above). I increased the fan speed to 100% and the fans stopped working completely, causing temperatures to rise rapidly to 91°C and 112°C junctions. As a result, I had to halt the upscaler and lose about 90 minutes of progress. Now I’m struggling to get the fans to exceed 50% speed; they either shut off or give erratic readings. The RPM sensor is fluctuating wildly, showing values between 209 and over 61,000 RPM, while hwinfo reports a minimum of 209 and a maximum of 61,325 RPM. No other problems like artifacts, glitches, or noises have occurred, and the system remains stable otherwise. I reset the GPU to power off and on again, but it didn’t help. I haven’t updated the BIOS recently, and I haven’t encountered similar issues with this card before. After searching online, I found only vague advice like “try a different card” or “do a DDU and fresh install.” Before spending more time troubleshooting, I wondered if this was actual GPU damage or just failing fans. I’ve used this card for mining in the past, so it usually handles high fan speeds well—though its cooler/drams are lacking, with only two chips getting adequate heatsink coverage. I upgraded the thermal pads to ThermalRight Extreme Odyssey and ensured full pad coverage even when the cooler wasn’t performing well. I’ve dealt with dead fans on other cards before, but this sensor behavior is unusual. I’ve saved screenshots of hwinfo showing my specs and readings; please check if they’re helpful. Any advice would be appreciated.
You seem ready to experiment with GPU settings. Those numbers really baffle me. Fixing this device would be way too frustrating for me. However, I’m sure there’s something worth checking out that could help you too. Unplug the fan headers from the GPU. Clean them thoroughly and rinse them off. Allow them to dry completely (this has worked many times before, it restored function and cut down on noise). Once dry, take out the fan headers. Replace them with a standard case fan from storage, disconnect its wires, and solder them onto your GPU fans. Connect the fans directly to the motherboard. Fine-tune the fan curves as you prefer.
At that stage, I’d just remove the GPU and install some 120mm fans. You won’t have to worry about soldering either.
