Best Quietest Attic Fan 2024: Reviews

1. Quietcool QC CL-2250 Whole House Fan

The QuietCool QC CL is a super quiet whole house/ attic fan that stands out among others in the market. It’s known for its powerful performance whilst remaining quiet. This is thanks to the design using an acoustically insulated duct to absorb noise. This in no way reduces the amount of air being moved as it still moves as much as 3,126 CFM.

Apart from its silent performance, the QuietCool attic fan is also easy to install. Installation can easily be done through your ceiling with a duct box. The fan is positioned at the far end of the box to also minimize any noise from the fan from being heard.

Another alluring feature of this product is that it saves you energy bills. Compared to a quiet air conditioner, you will save up to 50% of the energy you would spend on A/C while even going further to cool the thermal mass of your attic. With the RF control kit, you don’t have to be next to the attic fan to control it. Even from up to 100 yards, you can turn your fan on and off.


  • Quiet control
  • Ensures clean indoor air
  • Energy saver
  • Can be controlled from anywhere
  • Easy installation


  • Insulated doors are not included

2. iLiving ILG8G14-12T Attic Fan

This iLiving Attic Fan is especially recommended for those who have access to their attic’s gables. With this product, you don’t have to cut a hole in your roof as you can install it in the wall. Don’t worry about pests and drought coming in through the fan as it’s capped on the outside using a vent cover.

Made to be durable, this quiet attic fan has sturdy housing made of galvanized metal. You also get good performance from the 3.1-amp motor that provides up to 1,600 sq ft space with fresh air and good ventilation. There is a thermostat included in the package, so you can preset your desired temperature and have the system shut off automatically at that temperature.

These features make it clear that this is a value-packed purchase you’ll be making. Note however that the fan doesn’t come with its vent cover. So you will have to purchase that on your own to prevent insect invasion and drought from getting into your attic.


  • Sturdy and durable
  • Programmable thermostat
  • Uses 3.1-amp motor
  • Low noise level
  • Moves as much as 1,220 CFM air volume

3. Cool Attic CX24BD2SPD Whole House Attic Fan

The 1,300 CFM fan that this Cool Attic Fan has is powerful enough to pull enough air into the room for good ventilation. This is true for attics of 1,850 sq ft. You can now ensure that only clean and fresh air stays in your attic at all times while saving energy at the same time. The powder-coated finish it has is for weather resistance, for improved user experience as well.

For low noise levels, the design is such that it reduces noise without affecting performance. The bracing system gives a stable motor mount to reduce vibration and resultant noises. This of course is sturdier than the tube-style bracing and gives room for only little vibration. 

Those who are not fans of cutting holes through the roof will enjoy this as it can be installed through the wall instead. Don’t worry about moisture damage and corrosion as the product is made to be resistant to moisture damage.


  • Made using galvanized steel
  • Easy to install
  • Quiet attic fan
  • Pulls as much as 1,300 CFM air
  • Good enough for attics up to 1,850 sq ft


  • Needs a minimum of 600 sq ft in net free air intake vent area

4. Quietcool AFG SMT Attic Gable Fan

Even though the QuietCool Attic Fan is a gable fan, it can also be installed on the roof. You only need to buy the roof vent cover. At a top speed of 2830 CFM, you can cool up to 3300sq ft and can lower the temperature of your attic by up to 50 degrees Fahrenheit. This makes it a powerful fan and a must-have especially for those with large attics.

Being powerful, there is a tendency for it to be noisy. This isn’t the case however as the fan uses an ECM motor which makes it quiet. There is an inbuilt thermostat and humidistat to regulate the temperature and humidity levels of your attic. 

This is efficient with the 10-speed motor which self-adjusts according to the preset temperature in the room. The humidistat ensures that the humidity levels in your attic don’t exceed 60%, saving you storage and roof from damage due to moisture. With all these, the fan uses only 145 watts at top speed, helping you spend less even though you are doing more.


  • Gives up to 2830 CFM air 
  • Efficiently prevents moisture buildup, mold, and humidity
  • Comes with an inbuilt thermostat and humidistat
  • Quiet performance
  • Roof mount and gable mount designs


  • Temperature and humidity sensors can be a nuisance at times

5. Broan-NuTone 345S0WW Surface Mount Solar Attic Fan

We will be rounding up this review with something a bit different; Broan-NuTone Attic Fan which is solar-powered. With a whisper-quiet operation, it produces a maximum of only 537 CFM, and so it’s ideal for attics of 767 sq ft. This isn’t an ideal choice for you if you are looking for something with great power as this fan is low powered.

Its beautiful and low-profile design makes it ideal for everyone and every décor. With 28 watts of power generation by the solar panel, the fan can be kept working at full speed. There is no thermostat with purchase, but you can get one to help regulate the temperature of your attic adequately. 

The addition of a thermostat ensures that the fan shuts off when the temperature is below 50 degrees Fahrenheit. Thermostats are not originally included because the fan is supposed to be used even during winter, and thermostats will prevent the fan from working.


  • Easy to install
  • Whisper-quiet operation
  • Durable construction
  • Low profile design
  • Solar-powered


  • Non Adjustable solar panel

Quietest Attic Fan FAQ

How Can I Make My Attic Fan Quieter?

Just as with faulty quiet ceiling fans and shop fans, attic fans can get noisy. The cause of a noisy attic fan can be likened to that for a noisy ceiling fan. One of the causes could be loose screws. If this is the case, you can reduce the noise by tightening the screws.

Unbalanced blades can cause clunking noises. Try balancing the blades if you suspect your fan noise is because of unbalanced blades.

Worn-out bearings are another source of attic fan noise. By replacing the bearings, you will greatly reduce fan noise from this source.

Are All Attic Fans Noisy?

Most attic fans are noisy, but some work quietly due to their design. Examples of quiet working attic fans are Quietcool QC CL-2250 Whole House Fan and iLiving ILG8G14-12T Attic Fan.

Are Attic Fans a Good Idea?

Attic fans are a good idea as they help prevent moisture and mold buildup in your attic. This is useful to retain the integrity of your roof, and also preserve the quality of your stored property.

Is It Okay to Run an Attic Fan All Night?

No, it’s not necessary to run your attic fan all night. This is because your attic fan is best used when the outside air is cooler than the inside air. Apart from spending more energy, nighttime is cooler than daytime hence no need to run the attic fan as much. 

What’s The Difference Between an Attic Fan and A Whole House Fan?

A whole house fan creates a ventilation current by sucking out the air from the house and sending it to the attic. An attic fan on the other hand draws air from the attic and sends it outside.
