Castle Kylfläkt 40mm Mamba XL2/XLX

Castle 011-0100-00 - 40MM ESC Cooling Fan

• Input voltage: 4.8 - 7.4 volts
• Maximum RPM: 10.000
• Waterproof: No, remove before exposing ESC to moisture

• Remove the 40mm fan, fan cover, and screws from the package.
• Place the fan onto the top of the ESC heatsink with the open side of the fan facing away from the ESC.
• Make sure that the fan wire exits the same direction as the ESC receiver cable.
• Align the fan cover over the fan with the Castle word logo facing away from the ESC.
• Align the holes for the fan cover and the fan with the threaded holes on the ESC heatsink.
• Place a screw in any one of the four mounting holes and use a 2.5mm hex wrench to tighten to the heatsink.
• Repeat step 6 for the remaining screws.

• Remove the 40mm fan, fan cover, and screws from the package.
• With a P1 Phillips-head screwdriver, remove the 4 assembly screws that hold the plastic housing together.
• Carefully remove the top plastic piece ONLY. DO NOT remove the top heatsink, thermally conductive adhesive holds the heatsink tightly against the ESC. If this bond becomes loose or gets damaged the ESC could potentially fail.
• With the back of the screwdriver, press the fan cover and the fan out of the plastic housing. This may take some force, be careful to not damage the plastic housing.
• Place the new fan cover into the plastic housing with the Castle word logo facing away from the ESC.
• Place the new 40mm fan into the plastic housing with the open side of the fan up against the fan cover. Make sure the fan power wires are exiting out of the molded wire relief in the plastic housing.
• Once the fan and fan cover are in place, align the plastic housing back onto the ESC and place the same screws into the housing that were previously removed. The four M3 socket head screws that came with the 40mm fan kit will not be used for this ESC.
