If you look in my video sleeving guides I have made one just for fans. (link is in my sig or stickied in the sleeving subforum)
The sleeving uses can be your normal 1/8th or small sized sleeving. However your heatshrink will need to be a bit larger for the method shown in my video but it can be done using smaller and not over the fan head. It comes down to preference.
