What is gable mounted fan?
Gable-Mounted Attic Fans: Like a roof-mounted attic fan, a gable fan is a fan you install in your home’s attic to help ventilate it. They help decrease wear on your attic’s materials while decreasing the ambient temperature, helping to bring your electric bill down.
Are gable vents worth it?
Many roofing contractors discourage using a gable vent with ridge vent and soffit vents because a gable vent interrupts the proper airflow and can cause the air current to flow perpendicular and unevenly throughout the attic. Be sure to keep them clean for proper air flow.
How do I get fresh air in my attic?

Can you mount a gable fan on the roof?
To save time, use an existing roof or gable vent to install your new attic fan. This way you don’t have to cut a brand new hole, but simply make the hole for the vent larger so it can accommodate the fan.
Should I install a gable vent fan?

Can you have ridge vents and gable vents?

What temperature should a gable fan be set at?
When it comes to an attic fan’s temperature setting, it’s best to adjust it to anywhere from 90 to 110 degrees Fahrenheit. It’s impossible to state a single number because your attic can effortlessly soar above 95 degrees (on average).
