Is the 80mm quieter than the 120mm?

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.

Mine is extremely quiet, especially compared with other models I have owned.

This is my first purchase and I am not sure how the other models are. I only know the one I bought (J8005) is super quiet. Really nice.

On the low setting its barely audible. Even on the high setting its pretty quiet. MUCH MUCH quieter than a fan with "hard" blades.

I have the 140 in my kitchen and it is not noisy at all. The only noise it makes is when it's pumping water into the heating chamber and it's not enough to even think about. I love mine it's bullet proof.

Either will work. The top has mounting holes for both 120mm and 200mm. Honestly, though, I'd recommend the 200mm fan. The bigger the fan, the more air it moves, AND the quieter it is.

I measured 86 dB right below my fan on high. Belt drive is supposed to be quieter. Higher quality is quieter too, but much more expensive.

Yes it is much noisier than a typical internal device. I suspect it has something to do with its compact size

I do not know which one is quieter, but I didn't think either were noisy. I do like the position of the split keyboard better. I returned this model as I did not like how scooped the keys were. Love the other model.

I think mine makes less noise than the one it replaced, but it is certainly not silent. It's all relative, I guess.

It is powerful so it is louder. But it is a lower sound of machine noise. Well worth the price.

its a lot quieter than I expected, definitely quieter than my co-workers fans that are similar. just a little humming, no extra noise when it oscillates.

Mine is actually very quiet. I had another model that was extremely noisy, so I am very happy with this model.

It's quieter than my central vac, when near it. It's quieter than my table saw, jointer, or planer, but louder than my band saw or drill press.

Some what quieter. I always remove mine when back to not being amped. Be mindful to buy the correct hole size.

Quite a bit quieter than my old one. On the high setting you can still hear it, but I generally use the middle setting and it is much more efficient and WAY quieter. Remember you are getting about 80% of the flow for 50% of the electricity, and about half the noise.

Pretty quiet. I have an i5 in mine with the standard intel cpu fan and that fan is louder than the one that comes in the case.
