Sorry, but there's no fan rotom in Pokemon Diamond. You can get a regular rotom in the Old Chateau at night in the TV Room. Talk to the TV and a Rotom will come out; it will be level 15. You can only get one.
tap the tv at night. it will get rotom out.
To encounter Rotom in Pokemon Platinum, check the TV in the Old Chateau at night.
You can get Rotom at the Old Chateau in Eterna Forest. Go to the room with the TV. Press A on the TV, and it will ask you if you want to bump the TV. Say yes and the Rotom will come out and battle you so that you can catch Rotom. (You need to go to the Old Chateau between 8pm and 6am.)
