Recently my cpu fan has started making a clicking sound when first starting up-it later goes away when sysyem has ran 20-30mins. At first i thought a ribbon cable was being hit by the fan blades (thats how it sounds) but after rearranging all the ribbons etc it still occurs. Does anyone have any ideas what may be causing the problem and what would you suggest would be the best way to solve the issue. My mainboard is a msi k8n neo4-f platinum but when my previous board caught alight (faulty solder) the people replacing it used the fan from this board for my new one
