Add a cooling fan to your x1 a must upgrade for quality printing parts, this mod will work with the same type of fan used in p802ma printer and will also be compatible with the ring duct, I would recommend using v1 of the ring duct, but that being said v2 will work just really close to the bed. Assembly is quite straight forward you must undo the wheel assembly on the extruder and drill your own hole( since this seems to change from machine to machine ) reassemble with same screw and nut.
Thing you need, dc brushless fan, model: yd-124010S.
Optional but works wonders, pretty much a must. P802MA or Anet 8 Ring duct.
