Product Overview

  • Built-in thermostat for ultimate convenience
  • Helps maintain attic temperatures to improve wood conditions
  • Attached brackets allow for easy mounting
QuietCool Attic Fans work almost everywhere, almost anytime. During the summer, an attic can be 40-50° hotter than the outside temperature, which in turn heats up the house very quickly. With an attic fan, you can cool the attic to the same temperature as it is outside, greatly reducing the house from heating as quickly. With the QuietCool Smart Attic Fan, gone are the days of having to adjust the thermostat for your attic fan. When the fan detects temperature over 80° , or humidity over 60%, the Smart Attic Fan comes on at the lowest speed. As the attic starts to heat up, the Smart Attic Fan automatically adjusts it's speed. The QuietCool attic fan is able to keep the attic cooler since it ramps up the speed of the motor in accordance with the temperature in the attic rather than a standard single speed attic fan that would come on at a higher temperature.
  • Self-adjusting 10-speed ECM variable speed motor proactively cools and ventilates the attic
  • Moves air at a rate of 963 CFM at the lowest speed to 2830 CFM at the highest speed
  • Built-in thermostat and humidistat
  • 15-Watt on low speed up to 145-Watt on high speed
  • Installation is simple with the integrated mounting brackets
  • Mounts directly to your existing gable vents in your attic

Can the humidistat be defeated or adjusted?The specs say that the unit turns on when the humidity is over 60%. But in Vancouver or Seattle the humidity is almost always over 60% especially in cool weather when the fan is not needed.
Asked by: Roland
Yes, the instructions for by-passing the humidistat are right in the directions, Section 3.1.5: "TO DISABLE THE HUMIDISTAT, TIE THE BLACK WIRES AND THE RED WIRE TOGETHER." (Although the accompanying diagram is a bit confusing, in that it incorrectly shows the red wire coming from the power source; the red wire comes from the fan housing, where the humidistat and thermometer are located. SEE DIAGRAM BELOW). But regardless of that, when you open the junction box at the end of the conduit, you'll find the black wires connected to each other (ditto the white, of course) but the red wire is capped, not tied to anything. With the power off or the plug pulled, just take the wire nut off of the red wire (strip the last 3/4 inch) and remove the wire nut off the black wires, then tightly wind the red wire around the black wires and reinstall one of the wire nuts over the three of them. Now the humidistat will not control the fan, only the thermometer will control it being turned on or off and will govern at what speed the fan runs.

Comes on at 80 deg F on lowest of 10 speeds, then increases as needed until its highest speed at 125 deg F, which sounds like a jet engine. Moves alot of air.

I'm trying to work out the Net Free Vent Area math for this product with my attic space. The installation instructions state that 1 sqft (144 in^2) are required for every 750 CFM output. Furthermore, the specs show that the CFM range from 963 to 2830 depending on temperature. So getting to my question...... If the radius of the fan is roughly 8" (possible 8.25"), 3.14x(8^2) = 201 in^2. When the fan is running at the upper speeds, how does it provide the required net free vent area? 2830 / 750 = 3.77, so I need closer to 542 in^2 of net free vent area. Where do I get the balance required? My roof has some off-ridge vents also. While this unit is running and pulling air out my gable, will these vents effectively become intakes? I haven't calculated the inlet requirements but those seem much more straightforward to me. I'm not sure if pitch comes into play here also, but I have a 2/12 roof. It's a fairly large attic, but I probably only require 700-800 CFM routinely. Any help on this would be greatly appreciated. Perhaps my assumptions are wrong regarding the math.
Asked by: Ben
I'm not an expert on attic ventilation -- I am only someone who installed the Smart 2830 and thought about similar questions. The vent area (as you correctly calculated) is recommended to be at least 3.77 sq ft. However that doesn't refer to the outlet size (16" dia. circle, 1.77 sq ft). It refers to the sum of all the inlets around the house, such as soffit vents, including your off-ridge vents (as I understand). If you have the minimum recommended vent space (3.77 sq ft which is about twice the outlet size), the inlets will be pulling air in at half the velocity of the outflow. I also have off-ridge vents (one about 10' from the fan). I did consider taping over (actually, under) that one vent nearest the fan; since I have the fan, that vent isn't needed. So, if you or I get rain on a hot (sunny??) day, I guess there is some possibility of pulling in tiny (micro) droplets with the air. If the day is overcast & 80 degrees or less, the fan speed seems really low and I'm not sure how much might be pulled in. But if it was sunny and the attic temp was at 125F (max speed) when an afternoon shower hit, there might be some tiny droplets from raindrops hitting near the vent and splashing micro droplets into the air. But even in Texas summers, the rain is cool enough to quickly drop the air temperature to below 100, reducing the fan speed & indraw. Rain clouds usually block the sun, reducing the heat load on the attic. So, I don't think that the condition would last long. Also, the fact that the fan will run until the humidity in the attic is less than 60% would also reduce the chance that the moisture from the droplets would last long in the attic. All this is just my opinion. You may want to consult an expert. Minimum speed of the fan is 963 cfm, or 16 cf/sec. The air is exiting at 16cf/sec / 1.77sf = 9'/sec. The air entering is 16cf/sec / 3.77sf = 4.25'/sec. That seems fast, but the velocity will drop very quickly as the distance from the vent increases, as it draws from the half-sphere around the vent's entrance.

i bought this and although it turns on very high it soon winds down and regulates to the temp of the barn installed in. but.............never turned off. Manufactures says it has a 80 degree turn on off threshold. mine was running all night in 60 degree weather. Anyone else have this issue. Waiting from the manufacturer to get back to me on a solution. Not a good fan if it does not shut off at its limit. means will run when it is winter time, thus opening up the automatic louvers and letting cold air, snow and rain in.
Asked by: hooziz2005
I'm a bit confused by your statement. You say it turns on very high, but your also say it never turned off. How could it have turned on more than once? I can only compare it to my experience. When I first gave it power (daytime in June), it did turn on high because it was something over 90 in the attic. But after 10 months, most of the time I can't tell if it is on (at the lowest speed) or off unless my house is very quiet. As documented, it will turn on (15W speed) if the temperature is 80 or above OR if the humidity is 60% or above. So, yes, it may run in the winter. If I lived where that was an issue, I'd unplug it or have it plugged into a switched outlet so I could turn it off for the winter. It seems like a pretty easy solution, but I don't live where the humidity is above 60% almost all the time (or might your barn have something that causes the humidity to be high).

The fan seems to be well designed overall, but the instruction manual did contain a confusing error regarding the extra "red" wire which, according to the diagram, was located in the incoming electric wire when it actually comes from the fan assembly. It is that wire that, also confusingly, comes with a wire nut attached to "dead-end" it and must be connected to the black wire in order to disengage the humidistat (presenting an illogical proposition to the installer). While shipping these units with the humidistat hooked up (with a 60% humidity threshold for making it run) might make sense in hot and dry climates (e.g. SOCAL), in the Southeast US it makes no sense at all since it will run continuously practically year-round. It would make sense to have two different models for shipping into states where the humidistat needs to be activated vs. other states where it shouldn't be. Although it should be acknowledged that it really isn't a big deal to hook the red wire into the black wires if one can get past the two logic tests noted above.

At best, they lasted up to around 5 years and were very basic fans with one speed. My new QuietCool Smart 2830 fan came faster than anticipated delivery straight to my front door. Mounting and start-up were very easy. It came ready to plug and play; however, I chose to hardwire it instead of the plug in. Upon application of power, the fan does a diagnostic start-up as described in the instructions. The fan runs at a quiet low speed, kicking up one speed from 80 degrees, every +5 degrees until it reaches full speed (10 speeds). I do not think it is very loud for what it is; though some reveiws complained about the noise. If you follow the instructions and recommendations, such as caulking the screen on the gable vent, you can minimize the noise. This fan is still quieter than the "off the shelf" ones I have used in the past. YES, I HIGHLY RECOMMEND THIS FAN TO ANYONE AND EVERYONE!!!

Rated 4 out of 5 by from So far so good. Note you cannot adjust the thermostat humidistat settings as far as I can tell! I'm in TX which means this will be on almost constantly. It also comes with a plug which is good to know. So we added an outlet in attic from the line off a second ceiling fan in room and merged that fan with the other fan so those ran off same light switch. Now the abandoned light switch operated the outlet that this fan is plugged into in attic and I can turn it off if I wish to from my office via that switch. I was worried about not being able to adjust settings and didn't want to climb in attic to unplug it every time I wanted it off and it didn't go off on it's own (until I learn its routine and trust it). Otherwise, easy install. Pretty quiet. I can tell it's on when I'm in the room it's under and when outside but it's not really loud, just a low humming motor noise. The last few days since install have been cooler so it's hard to say if it's helping with reducing my AC cycling all the time. Time will tell I guess.

I installed this fan on piece of 5/8" plywood that I had cut to fit over the gable. This made the installation easier as it sealed up the gable completely to prevent any blow back. I applied the silicone sealer under the mounting tabs of the fan, and around the fan base also. The fan is really quiet and I have no vibration at all. I can't even here it when the attic door is closed, and my bedroom is only 15' away. My attic is huge with a walk in door, storage area and 3 gables. I only needed 1 fan to cool it off. It's about 20 degrees cooler inside the attic. This past weekend the outside temp hit 109 degrees. Usually it takes the whole night before the 2nd floor to cools off. When I went to bed at 10pm the upstairs was already cool and I didn't even need to use the portable AC unit to cool down the master bedroom. The whole 2nd floor was about 10 degrees cooler than usual. I've only had this fan for a little over a month, but I highly recommend it. I wish that I would have done this years ago.

I would recommend it for a shop building on a farm where there is nobody nearby. I worry our neighbors will be bothered by the noise on all but its lowest speed. On its highest speed, I fear the neighbors in the next block will be bothered. I saw a review before I bought it by someone who said it sounded like a jet engine. That was very accurate for its highest speeds and I wish I had heeded their warning. I will be replacing it with a Broan like the one I was replacing because it made a hum (this fan also hums on its middle speeds, AND it rumbles and makes low/high frequency white noise, like the jet engine description). What a waste of money.

We replaced an old, noisy one-speed attic fan with the QuietCool Smart 2830. THIS FAN IS QUIET, but not silent, as it moves a lot of air! Other reviewers have complained about noise, but I don't know what they are comparing this too. The best thing about this design is the fact that it runs at 10 different speeds depending on temperature. So as the attic starts to warm up in the morning, the fan comes on at a nearly silent low speed, then gradually picks up speed as the day goes on, and then slows down again in the evening. A huge advantage over the roar we used to hear while trying to enjoy the backyard as the evening cooled off. From inside the house, when the fan is running at full speed, we can hear a quiet hum in the upstairs room nearest the fan, but otherwise it is undetectable. To install, we first cut a circle in a piece of 3/4" plywood, with new 1/4" hardware cloth well-stapled to the outside surface of the plywood. This was screwed to the wooden frame of our gable vent, and the screen was not able to touch either the fan housing nor the wooden slats of the gable vent. As other reviewers suggested, I put 4 vibration dampening pads (mine out of old pump gasket material), to place under each of the four mounting tabs, but I'm not sure how necessary that was. At any rate, with the screen well isolated from the fan and gable vents, and no vibration, all you can hear is moving air. I'd definitely recommend this fan.

Took me about 3 hours, but only because I am slow and working by myself, and I had to take the old fan down. The new fan is much quieter than my previous fan. I had to disconnect the plug that came with it so I could hard wire it. No problem. I wish the 4 flanges were a lot longer. The flanges are used to mount to the gable. I was able to take the much longer flanges off the old fan and use to mount the new fan, which took some time to do. Will report back with an update after some use.

In May during cool, very early morning hours (5 a.m.) I can hear the very soft hum of the fan going. (This feature can be disabled however.) Now we are starting to get slammed with hot weather, I am excited to monitor both our comfort and utility bills to watch for a change in charges.
