How quiet is this at top speed, CFM 1360?
1087362
In a room with no carpet or other acoustical dampeners, my 20" 9166 is 80 dB at the fan, 72 dB ten feet away, and 68 dB twenty feet away.

Well, I suppose I could give you a dB reading from a meter...but my feeling is that it is not quiet. It depends on how well you have it mounted and isolated; it is very powerful and will shake the studs/wall if not well mounted. Mine is mounted into an attic access panel right now and in the furthest room from our family room and bedroom...it is no problem to watch TV or sleep...I mean very little noise in that scenario. This is a powerful fan so I would consider that when mounting...it is also really a whole house fan and should be put in an area where it is not right of you whn it is operating to exchange air.

If you have a 2 story house, you will here it downstairs, but not to the extent that it would interrupt anything like TV, etc. The master bedroom is on the second floor, and the fan is in the 4th bedroom down the hall from us. We have left the fan on all night on low, without any disruption in sleep. We used to have an attic fan, and this is considerably quieter. Hope that helps.

I wouldn't want to sleep in the same room, but other than that, it's OK. Works GREAT. Pulls a lot of air.

Very quiet. Been using it for 3 weeks now and it blows the stock fan out of the water....cooling

Not significantly. If you are looking for a quiet solution and are somewhat electrically savvy, try wiring two fans in series and ditch the speed controller. I found this configuration was much quieter (practically silent!) than using the fans on the low setting of the speed controller, and still moved a surprising amount of air. The speed controller is not a very "elegant" design, and causes the fans to emit a buzzing or humming noise at low speed.

Its pretty quiet when just tuening on its in my 5.7 merc 21 ft mariah. When the motors running dont hear it at all. It works great

Just OK. It was louder than the Frigidaire unit I have replaced it with but I didn't consider it objectionable. It has 2 fan speeds and is predictably a bit quieter on the low speed setting, in the same range as a window air conditioner on a low fan speed setting. I couldn't hear any compressor noise so it was just rushing air white noise.

I think it was 300 cfm. Not sure, bought it last year. Works well, makes a whine but not too loud.

I run it on f2 and it is not any louder than a normal fan. F3 is a little louder but no need to run it on f3. I forget it is even running.

Not sure, but I know there are some that advertise quiet fans but you cannot move 500 cfm without some noise.

It can be noisy; you can manually set the speed via the speed control knob on the back of the unit. When set at max yes, it is VERY loud. At its lowest it does create a low hum. Temps only decreased maybe 1-3C, during heavy system load it kept my GTX 670 reference card at a nice 57-60C.

On high speed it is pretty noisy,but not more than a bladed fan. I'm pretty sensitive to noise so maybe it's me. On low it is just fine

Its actually not that loud! I did not use this PSU for very long before switching to an XFX PSU which I like better and feel that it is more reliable then the raidmax.

I don't think it's noisy at all. The only noticeable sound I can recall of comes from the fan, still quite discrete.

It is very quiet on low. I have it running all the time and it sits on the other side of my small den, and I can't even hear it running. On medium, and high, yes it gets fairly loud, but I rarely have to put it on high. It is a great air mover, and will blow everything off your desk if on high. You can't go wrong with this fan. In fact, I am about to buy another for my bedroom.

Fan noise is not that bad; at least for the 3-cell, 120 G model I bought. It's as quiet as a normal laptop computer.

None, only at 100% fans speed (force set by after market software). You won't hear it under your CPU cooler - be it air or water cooling.

Hello, According to product literature, the noise level on high speed for this fan is 58 DB.

I have one at work in an open-case tower and I've never noticed it make any significant amount of noise whether the card is fully utilized or idle. It's pretty quiet overall.
