The cap across the fan will cause a large current spike when the 
transistor turns on and probably kill it. If you look at the 
schematic you'll see why. A cap to ground from the positive side of 
the fan should work fine.

The choke alone works fine because there is already a significant 
decoupling cap on the 13V line.
