How much noise does the fan generate over the power range of the inverter?

The fan only comes on at high demand, when the unit is generating a lot of heat due to the load.I have been using the unit daily in my semi to power my laptop, printer, and charge the phone, and have yet to put enough load on it to engage the fan. I did load it up when I first got it with a soldering gun and a vacuum, and the fan was virtually silent. This inverter does all its supposed to do, and more.

I haven't put enough of a load on it for the fan to kick on. I use it for all my electronics only at this time. I plan to buy a low amp refrigerator, it may kick on then. My Cobra has a loud fan, but is still an efficient inverter.

We use the inverter for our electronics in our fifth wheel and haven't even noticed the fan noise.

I have not measured the volume in dB, However it is much quieter than the case fans and CPU fans. I currently have it in my workshop in an open air environment, so I never hear the thing. The fan is 140mm I believe, and is controlled by temperature. The intelligent fan control keeps fan noise to a minimum below 45C. Which it never reached, even while mining in the summer. Regardless, it will be a very quiet unit for most applications. Look for the review at Johnny Guru for more info. -buzznut

Sorry, I never thought to look. All I can tell you is that it is installed in a normal 15Amp 120volt system and works great. It makes no noise while in operation. I have found no fault with this device.

This power supply is low noise, this means that the fan is activated when required, if still not activated and you've got a claim guarantee, but is the site you can find Coursair

The sound is normal. The unit has higher power use and needs a fan to cool the unit.

This fan is in it's second season in a small storage shed. During the summer it runs 18/7 as I have a thermostat on it. Shuts off when it cools. It is about the loudness of a ceiling exhaust fan. Best answer I can give.

Never noticed a fan problem. I can hear it, but it's quite minimal (and I'm sensitive to noise).

Its a high frequency PWM (15khz), so not audible in my setup. Im using it in a small motor so I cant hear any whine. Im not sure if this would be the case on a larger motor under stress.

There is very little noise with my unit when the fan isn't running. And the only times so far that the fans have kicked in were when I had it hooked to my TV as an external display. Don't get me wrong, the fans are far from silent when they do kick in, but with fairly normal use, they usually don't.

I build a theather pc and power supply fan is very loud u will hear it at night and it will bug u unless u can turn the tv very loud

I don't know how much power it uses but it was so noisy that I returned it. Good luck.

Yes it is as quiet as can be expected...usually the noise generated from a PSU fan is the bearings starting to wear...we had a great experience with this fan...hope this helps..

I have never noticed any fan noise coming from the unit. I believe the unit will power a refrigerator depending on the size of the refrigerator, W hen I had a question about my unit i just telephoned the company and talked to a technician.

Same as almost every other power supply but still very quiet, and more quite than other case fans but since it's a cheap per no one has taken the time to measure it in dB, sorry. And I had to return mine.

Use the formula Volts x Amps = Watts. The volt and amp rating should be on the fan info label. So with this inverter you want the answer to be below 150 watts, but add some safety margin, perhaps 130 watts max load. (The manufacturer should have built in a safety margin also).

Sorry for the delayed answer. The fan is not at all loud. Definitely less noise than my full-sized HP.

The noise level is based on how fast you set the fan. On the lowest setting it is pretty quiet. Even on the highest setting it isn't that loud.
