Are these noisy, was planning on using 2 to vent open beam living room, not attic? Very hot here in Hawaii

I install one on my attic and to make sure it is working I have to look to see if its running. They are very very quiet. Go ahead and buy it with confidence. This are the best, there are some less expensive but the housing is made of asfalt, and if its too hot they can melt. I recomend it.

It's in our attic and I don't hear anything I don't know about an open area.

Just the opposite, very quiet! I have to really listen hard just to make sure it is running, not like the ones I've had in the past.

When I'm in the attic, I hardly hear the fan running. At full sun, the fan chugs along with very little noise and it's only a few feet away from the attic ladder. I'm considering getting another fan for the lower attic to keep that area cooler. Hope this helps.

The noise from the fan is not bad...more of a hum. Easy to adjust to...and not notice to much. We do feel it helps cool the second story very well.

They are very quiet, turbine sy=tyle impellers and a well designed housing. vertical /horizontal mounting options, etc.... I am running four of them, and the "whistle" and "air noise" is louder than units themselves..... Good stuff.. the person who answered with a #7, must have a poor mount or something, they are very quit.Frantic1

I own a small cabin back in the woods. I have two of these elevated on either side to cool it down in the summer. I sleep with one on low not 7 feet from my head. Noise is not an issue. Of course on high, it gets a bit loud, but that is the sound of moving air, not the fan itself.

I really have not noticed them being very loud. I have 2 of these mounted on my 212 evo cooler that average running around 1700 rpm's to keep the overclocked I7 cooled to 30-40c. Go go them if you need some serious air pushed in your case.

The speakers sound just fine on a table. But on a mattress or a pillow or something like that, the sound will be muffled, not to talk about the damage the heat from the fan does. Use a plain hard level surface and you'll be fine.

Technically this is difficult to answer, without seeing your exact set up. The big issue with these is that they do have specific venting requirements, with special pipe etc. If you can satisfy those, you should be good to go as the unit itself does not put out a lot of heat (ours is a 2 person household. YMMV if you have this running for hours keeping up with multiple showers etc.) Our hangs in a relatively tight attic "crawl space" in condo - and very satisfied.

I feel the same way...very loud. I thought mine was defective, but spent so much installing it and cutting the ceiling that I will just deal with the noise.

I cannot directly compare this fan noise to other similar fans, but the noise I hear inside my house is comparable to my upstairs AC unit, not bad at all. Also, the fan goes off after the upstairs temperature drops to about 95 (10 deg. Below my setting for it to come on), so it has not been running at bedtime. Outside the house and on the same side as this gable mounted fan, it is noticeable, but not overbearing. I am very satisfied with all aspects of this installation so far.

I have 2 air conditioners in the house, both sound about the same, however they are both fairly new. Installed correctly, this is not an excessivly noisy air conditioner.

4 elements. We have an older house with lower ceilings, and one keeps our living room comfortable, and not at all noisy. Yes, there is a fan but I don't think it's any louder than my central heating fan. In a bigger space I would buy one bigger unit than use up 2 smaller units more quickly.

They make loud beeping when turning them off and on and /or adjusting the temp setting. But while running they are not very loud. They make some noise when reaching the set temp and turning off and back on. The usual clicking, but be warned they beep loud when making any adjustments. But if you close the bedroom off, they will keep it warm. So far this year our low had been wind chill of -10. And it kept our 15x13 with 13 ft vaulted ceiling bedroom very toasty. Had to come out from covers. So it more than makes up for the occasional whirring and clicking.

they are fairly loud. they drown out a lot of the engine noise on my 62 falcon if i'm standing next to it while running. i have 2 installed, louder than an average electric fan. i also have mine mounted in front as pusher fans, that may make a big difference

I've only heard one other fan, it was like a hum. Ours is above our bedroom & walk in closet. It's like a free standing fan as far as noise. I don't reallynotice it as we've got two ceiling fans going at the same time. If the ceiling fans are off I hear the attic fan but it doesn't keep me from falling asleep.

Ours, ceiling mounted, runs quite warm. I second the recommendation to use standoffs to increase airflow around the unit. I suspect that will help it last longer.

I have five of these fans in a solar kiln for drying lumber and standing outside the kiln while they running all you hear is the minor sound of fans and a little drone of the motors. In my opinion they are very quiet and if they were installed in your attic you not likely notice them in your living area. I didn't measure the length of the cables by my guess is that they are somewhere in the 20 foot length, maybe longer.

I think in very well might be better to install 2 of them. I have a single level 2400--but has a bonus room above garage--and a very tall attic space. I got 1 and it is only cooling my attic 10 degrees or so in the heat of the afternoon. I may look to buy a 2nd one later on down the road.
