Years ago, a fellow named Bill Thomas was modifying and racing Corvairs. They removed the sheet metal under the motor to remove some weight from the car and the motor began overheating. They found that without the panel, air coming from the front of the car made a 90 degree turn up into the motor while the fan was trying to blow air downward through the motor. Result: stagnation of air and no cooling going on. As soon as they re-installed the panel, the motor ran at its usual temp.
