There is a persistent, loud buzzing sound coming from my XPS 8700 (within the case) when a fan is connected to SYS_FAN1 on the motherboard. The buzzing sound completely disappears as soon as the cable is disconnected.
What could be causing the buzzing noise? Could it be fan speed? If so, is there a way to regulate it? Could it be coming from the motherboard?
Thanks in advance for your help.
I have the exact same issue. I have seen it on three separate xps 8700's. Dell has yet to offer up a solution to the problem. I am also experiencing buzzing from the headphones on conjunction with a discrete graphics card.
One of the only solutions I've been able to think of for the fan is to power a fan from the power supply directly and obtain one that has attachments to reduce the rpms. This is terrible behavior for a desktop computer.
Does anyone know if there is a way to monitor or control the fan speed?
I can see the temperatures on Linux, and probably Windows. I think most motherboards let you see the fan speed too, but the Dell doesn't? I searched for this all over and can't find it.
