Re: dc7100 CPU upgrade

Hi again, I upgraded the CPU with a 670 3.8 plus microcode update, all works well except the fan is almost always running flat out. Tried re applying thermal paste etc, no difference so bought what I thought was a compatable heavy duty/quieter fan

Lights up, starts to spin then stops.

Any ideas?

Thanks
