Does the fan turn off at lower loads? how quiet is this psu

No, I don't think the fan turns off at lower loads. It's a very quiet psu that I can barely hear.

No, the fan stays on at all times. It is not a loud fan. If you have other fans in your computer, it won't be any louder than them.

It does not completely turn off, however it is very quiet. I have my tower on my desk next to the monitor, and I cannot hear the power supply over the CPU cooler.

It's pretty quiet. When I have my computer on I don't even hear it, only the sound of the fans in the computer.

it has an open design and the sound varies depending upon how many other fans you have running. I have a corsair cs550m powersuppy and just the cpu fan running. If I'm not view a video, transcoding or compiling a program the cpu fan can be noticed but otherwise its quiet. I don't run the side fans at all as they added some noise but they may be necessary if you plan to put a GPU card in it.

It only has one official speed (900 RPM) and it's pretty quit. They say it's 11 db. I have no idea if that's accurate but it seems quiet enough. If your motherboard allows you to change the speed on 3 pin fans it can go slower and run quieter. You can also buy a fan controller and slow it down that way. I'm running two of them right now at about 640 through my motherboard control and they're almost silent. They still do the job of cooling my four SATA hard drives.

I have no problems at all with my Corsair power supply. It is working beautifully and is so quiet.

The one I got booted up fine and was nice and quiet during idle on the desktop. But load up an intensive game, and the fan was very noticeable. I could hear it from outside the room, down the hall, and downstairs. I returned this M12II and got a Seasonic X-850 GOLD Seasonic X-850(SS-850KM3 Active PFC F3) 850W 80 Plus Gold ATX12V/EPS12V Power Supply instead, and have been happy with it for the last 2 years and counting.

It's not bad at the low fan setting. Very noisy at high level though and if you forget to turn it off and sit down to eat with it on you will quickly get up and turn it off.

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.

No. I run mine (we have two) on a low speed and I only have a low hum from the fan.

They're pretty quiet. If you connect them to the motherboard you can lower the fan speeds in the BIOS. Otherwise they include an adapter that connects thee fans to a molex connector which is quiet.

The fan on my machine turns off when the reservoir is full. I don't think the RH ever gets low enough in NC to know if the fan keeps running or not.

The fans are quiet but I also have a ssd that helps keep the noise to a minimum. Some of the fans that came with the case not longer work :-/

It's a junk low of the low tier psu, spend the extra money and get a sea sonic or superflower made unit, my cx750 had major coil whine. I now happily own a silent evga g2 850w psu made by superflower.

It was not as loud as my other fans...psu cooler and video card. It was a great little psu for the build I used it in! It powered i5 2500k overclocked and two gtx 560 ti's in sli with no problems! Now days, two 670's would not use any more power than did the 560 ti's

the fan just work under high performance (when a large amount of power is required).Don't worry about it..

The fans are relatively quiet and the unit remains vool. No concerns but I need to call the manufacturer to set the timers-they are a nightmare!

mine does the same.. check your voltages in the BIOS though from what I've read it's the fan controller on the PSU switching on and off.. you'll be fine :)
