The pump starts making noise at less than 3000 RPMs. I cannot get the pump to stay at 3000. After an hour or so, it will decrease to 2200. Fan control software, and BIOS, are set to 100% power at all times. When the RPMs decrease to 2200, the fan monitoring software still claims 100% power is being delivered, while the RPMs are correctly reported as 2200. I can reset the RPM back to 3000 by going into the fan control software and turning the pump off and on. Obviously this is an annoying workaround.
The motherboard is Gigabyte Aorus B650M. The pump is connected to CPU_OPT. I have tried both control modes - Voltage and PWM. These random slowdowns happen in both modes.
Does this sound like a motherboard problem, or a pump problem? Any possible solution?
