Fan burnt chip FB4001 on motherboard

karacarm, if we are both looking at the same circuit board schematic, what you have there is Not a "fried chip". It is a ferrite bead (FB), which is in turn a component that is used as a filter to muffle unwanted interference in electronic circuits. Now it gets really interesting, there are literally thousands of those on here. Doing a search on the 1608 from the schematic cross reference to something like this and on digikey like that. You can also check with mouser.com and multiple other places. Hope this helps, good luck.
