Can water get into the fan electronics or inside the body?
No, the fans are totally sealed with a total of 4 o-rings. One is located at the front inside the bracket assembly, the second is inside the electronic compartment and the last two are located between the rotor bearing and the electronic compartment. Should any moisture enter through the shaft seal due to change of temperature and condensation, do not be concerned as all internal components are stainless steel or anodized aluminium.
