For best results, it is advisable not to place the fan directly against the window. A distance of between one and one and a half meters generally allows for better airflow direction outwards.
Those with two fans can take it a step further. The first can be placed near an opening to encourage the intake of cooler air, while the second expels hot air outside.
It is important to remember, however, that this solution has its limitations when temperatures become extremely high and the air is particularly heavy. In these situations, it remains essential to seek out the coolest spaces possible, to stay hydrated, and to find a truly cool environment whenever possible.
Sometimes the secret to better coping with high temperatures is not to change your device, but simply to change its location.
