Dell dimension 4550 fan running at full speed

[jamestanit]

It is

JMC/Datech
9232-12HBTL-2
DC 12V 0.85A
02.08.22 (printed in black letters, maybe added by Dell)
DC Brushless Fan
P/N 9M060
E186583

Now it is running at full speed. In the bios there is nowhere I can specify the settings. Are the temperature sensors on the fan or on the motherboard?

Thanks

At full speed it is very noisy. This happens even when the system has NOT started into windows yet.

It's difficult to give you an exact answer on your question as you haven't supplied much information...
ie: Motherboard make and model number, and if the fan is a standard case/chassis fan or CPU fan.
If it's a CPU fan, the fan speed is controlled by the motherboards temp sensors.
If it's a case fan, it could be running without sensors, or using motherboard temp sensors, depending on how the fan is set up and what connectors it has.

There is very limited information available on the internet regarding the particular model that you quoted.

I suspect that if this fan speed issue has only just started, that it could be the result of either: build up of dust/crud on your fan blades, or system overclocking.
