CPU fan always at full speed

[Chantho]

Since the faulty motherboard was replaced on my PC by a Gigabyte G41M combo, the cpu fan runs all the time at full speed.

Speedfan and Gigabyte's own Easytune utility aren't changing this, all ideas welcome.

Thanks

Bios settings have energy efficiency switch off?

The fan is connected to the right connection?

Thanks for the advice, unfortunately the Bios doesn't appear to have such a setting.

I'll get the hardware checked out in case of some issue with e.g. connections.

Advice I have found on the net has so far hit the buffers when it suggests changing some setting which I don't seem to have, ho-hum......

Your mobo will have multiple fan connectors, stating the obvious but you have got it plugged into the CPU fan connector and not one of the case fan connectors?

CPU fan poorly seated on the CPU? Bad/no thermal compound meaning CPU is hot, fan is not?

Dust! Is it all clogged up with dust?

Otherwise it's got to be a bios setting issue me thinks....

Probably dust.

Perhaps this would help.

Am assuming you're using Windows? If so then check the Task Manager -> Processes to see if a process/image is causing the CPU to go at 100%.
