The fan outline, screw hole layout and cable length are 100% consistent with original factory fan, no chassis trimming or wire cutting required for easy self-repair or professional maintenance. It is an economical cooling spare part to restore stable heat dissipation performance of Dell Inspiron P66F series mainstream notebooks.
