Hi - I am not familiar with your board but a quick read of the Technical Product Spec indicates the CPU is passively cooled and the fan header on the board is for the chasis fan. Check it out here. Regards. Peterhttp://downloadmirror.intel.com/19123/eng/D525MW_D525MWV_TechProdSpec.pdf
Thanks Peter, I agree with your comments. I was reviewing the product guide but the doc you referenced with a better tech source. Thanks again for your help and comments.
