I feel slight air movement in front and back of the machine, but it's totally silent. Fan speed doesn't seem to change flow strength. Defective? Fix?

yeah something's wrong then, mine sounds like a jet engine winding up when turned on. And the airflow increases quite a bit from the low to high setting, as well as the feel of suction in the back from the air getting pulled in. Make sure all the filters are pressed all the way in and the back panel is snapped on because it has a safety feature that wont let it turn on when that cover isnt on. If all that is the case and its still not working id return it, the next one will be fine im sure.

send it back. If it was working you world hear it. It is not a quite machine.

I have all fans connected and would say it's fairly quiet. My video card fan is louder then the rest.

Yes. with little activity the fan hardly runs. With more processing it really blows. I found the problem with mine was some Toshiba installed gaming that was running all the time. causing the fan to run on high all the time. I couldn't figure out how to turn the game off (or how it even got turned on) so I just uninstalled it and my machine now runs quiet.

barely... there is very slight fan noise, but it is VERY subdued and the computer is perfectly silent when the fan is not on.

I don't think it was designed like a laptop where there is no fan speed at all until the processor reaches a certain temperature. Mine runs all the time as well, but quiet with no load, louder with a load. The fan speed change is immediate too which shows to me it is load driven, not temperature driven.

The pump doesn't appear to make any noise, at least I can't hear it over the fan. Than fan is changeable with one quieter as long as it is the same size.

I think your fan may be defective. You should contact Ozeri customer support and they will be able to help you with the problem.

Watch out for a defective fan motor that changes speed by itself. You won't feel any air movement at all. If you are lucky enough to get one where the motor is OK, it does a pretty good job moving air up to about 20 feet.

The fan doesn't make much noise. Depending on the temperature setting, the fan makes a low "quite" hum.

It seems to blow the same. I do not use the cool button. I just turned it on and held in the cool button, and the air flow seemed the same.

Make sure the bag is clean and there are no obstrctions around the fan. Otherwise is most likely a control board problem and will need factory repair. I'm on my second one after first lasted 3 years. Decided cheaper to buy a new one than repair the old one.

The fan should be running but it should NOT be loud. I'd return it for a new one.

Either something is wrong with your fan or an installation problem, could something be caught in it? Ours is very, very quiet.

Either they have changed the specifications, or your unit is defective. The fan on my unit only comes on when I've had it under heavy load for awhile, then shuts off awhile after the load is reduced.

Honestly I can't hear it above the other fans I have in my case, and those are made to be silent as well. It's like it's not even running.
