Choosing your quiet attic fan

Quiet starts with the right match: a fan sized to your attic and intake vents, running at the lowest RPM that still clears heat. Pick placement that keeps sound out of living areas, and choose controls that avoid needless full‑speed operation. Do that, and you’ll get a cooler attic, less A/C strain, and a home that stays peaceful.

• Mount type: Roof‑mount keeps noise outside; gable‑mount is often the easiest retrofit.
• Power source: Solar = lowest daytime cost; hybrid (solar + AC) = 24/7 runtime; AC-only = consistent airflow on demand.
• Controls: Multi‑speed + smart staging for quiet most of the day; thermostat/humidistat to run only when heat or moisture rises.
• Sizing: Match CFM to attic size and ensure ample soffit/ridge intake; more free intake = cooler attic at quieter speeds.
• Climate fit: Humid regions benefit from a humidistat; sunny regions are ideal for solar/hybrids.
• Install for silence: Solid framing, rubber isolation, and tightened fasteners—loose screws are a common noise culprit—plus proper flashing and sealing.
