This is an Exotek 40mm Fan Mount Bar, a heavy duty 7075 alloy double fan mount bar for the Exotek 1/8 Fan Mount Clamp (#EXO1914 OR EXO1756 REQUIRED). Now you can easily mount 2 high powered 40mm fans to Exotek's 1/8 Fan Mounts- a must to protect your expensive high voltage motor package. Bolts directly to EXO1914 and EXO1756 for double the cooling power in high heat applications.
The fan mount positions the fans about 10mm away from the motor can. This proper spacing helps insure the fan does not lose rpm's due to magnetic interference from your motor. A fan that is placed too close to the motor can actually stop spinning as you apply maximum throttle due to the fact that the motors stronger EMF can slow or shut down the fans EMF. Simply splice 2 plugs together OR purchase a Y connector and plug the end plug directly into the receiver.
