Castle Creations ESC Cooling Fan 40MM Mamba Monster X 8S CSE011015100 Electric Motors & Accessories

Castle fan blades are really , really bad ,,,Blades break off all by themselves,,,Their esc's and motors are awesome ,,,But Their fans are crap ,,,After trying 2 of them I think it is best to replace them immediately with an aluminum case fan ,,,

Packaged as described, sealed, but 30mm fan came. Missed race season qualifiers

Both fans lasted two minutes I do speed runs so it’s not that hard on the fans so I don’t recommend it
