There are much quieter 90mm fans they could have used

If you have a mid-size or smaller, the cables will fill up a bulk of your inside.[---Fan Noise---]

Great PSU can almost never hear the fan and the cables that come with it look great

as of posting this, it runs like a champ with all the fans i have attached to its hub, good for about 2-4 years max

The PSU unit works fine, but the fan makes a slight clicking/rattle after 4 months.

of Full load the fan barely works or sucks any dust, I love this power supply.

If you're spending this much for a power supply, you probably have a few because you also spent $$$ on a decent mobo!This thing is also QUIET with a nice, LARGE fan.

The fan is nearly silent and hasn't showed me any reason to give a negative review just yet

The fan does not turn on until you reach a certain load (see graph) which makes it silent when possible, but it also has a nice, large fan which allows it to cool quietly when necessary

Fan is super quiet!

It's surprisingly quiet as well, tiny fans are usually pretty loud, but this one is quiet, but still audible

Had to check several times after installing that the fan was working.

My previous Corsair PSU worked fine for two years when the fan stopped working inside of it, I decided that since it hadn't taken any other components with it and that the only problem was the fan I would get another corsair product, this time with an upgrade in voltage from a 600

Fan broke

That isn't usually much of an issue for me anyway, but some users absolutely hate loud fans so Corsair is a great option because you can leave your fan on overnight, and depending what CPU cooling you have, you can have your computer be almost silent when it's at idle

12 FansUnder load, the fan is nice and quiet, and when at idle the fan shuts down for silent operation.

The good:- Silent Fan

Plenty of wattage, and pretty quiet fan.

Fan also made a horrible noise.

Modular, Quiet, Fan Speed Can be adjusted

Aside from the clicking sound when the computer turns on, this fan is quiet

The buzzing was quieter than the fan ramping which sucks now.

You know the cheap battery powered handheld foam fans that kids buy at toy stores

It replaced my old HX1050 (btw still working since 2012), which was fine, but had no fan switch (like Hybrid/Normal in AX860) as an option, making annoying spin starts/stops, and was kind of overkill for my workstation

Easy instillation, quiet fan, and works wonderfully

Quiet fan

The fan in my old power supply was making buzzing, grinding noises for a few months, so I bought this power supply as a replacement.

My only slight disappointment is that the fan is louder than my previous power supply

Recently the PSU starting making weird noises on PC boot up, almost as if the fan was loose but after a few seconds after the fan reached idle RPM it would go away

The fan in this power supply changes speed according to heat, so it is very quiet

The fan on that is so loud, I'm going to sell

not sure if it's normal for cooling fan to have a constant subtle rattle but i can't stand it, defect with the cooling fan/motor/bearings

not sure if it's normal for cooling fan to have a constant subtle rattle but i can't stand it, defect with the cooling fan/motor/bearings

The Zero fan is whisper quiet when in use and the fan test was useful to ensure the product worked (even though I also have a PSU tester/load).The corsair link and configurable 12V+ rails guarantee this will be in my next two builds, that along with an extensive 10 year warranty.

CX650 gave new life to my desktop, now more stable, easy enough installation, had to check if the fan was working very very quiet

fan is quiet and can't really hear any coil whine

Fantastic fan and cooling

Made it apart of my build and just gave a burst of power and stopped working... the fans move for a half a second but don't work

fan making rattle noise as if broken and cant get any help.......

and I prefer a supply that is less dependent on the fan and has the ability to survive even if the fan stops working

When the fan is actually spinning properly its the loudest fan in my PC

The fan is very quiet, and often times it isn't even running while in the hybrid mode

"Low noise 80 PLUS Bronze certified efficiency and clever fan design allow for little or no detectable fan noise during regular operation

Bonus cooling fan, plus it runs quiet just like before.

Running a 6700k and a 980ti at load, the fan still doesn't turn on and it totally silent

This PSU has a quiet fan, and the fan doesn't run under normal, light load

The fan became very noisy even under moderate workloads and was audible from across the room

AX860 sounds much better, I mean like it does not exist, no clicks when turned on, no fan noise behind the chassis and quadro's fans

Great power with silent fan

The fan made loud noises until it finally stopped and the unit began to smell like hot electronics

I had a 750W that just started making some weird fan noise but not sure the fans can be replaced but needed a bit more power

My previous Corsair PSU worked fine for two years when the fan stopped working inside of it, I decided that since it hadn't taken any other components with it and that the only problem was the fan I would get another corsair product, this time with an upgrade in voltage from a 600

Mine came with a defective, rattling fan

’s computer with this power supply for no other reason than the silent fan option.

Super quiet as the fan almost never has to come on (in hybrid mode)

Super quiet fan, that doesn't even come on in normal use.

At the time the fans I bought for the case were considered quiet

Fan stopped working.. overheated and the whole room smells like burnt xformer and Printed Circuit board..less than 7 months old.. do not buy this junk

First unit arrived with intermittent fan issue

The fan is extremely loud, and spins up quickly with even minimal loading

so I have no option as far psu goes, but if Silverstone sfx would use better and quieter fans I would pass on this psu

Higher end PSUs, like this one will offer modularity, lots of connectors, a silent fan, and sometimes monitoring options

The CPU Fan sounds like machine saw compared to this.

The fan on this power supply is very quiet - much quieter than my other CORSAIR power supply

While gaming, the fan ramps up but even at the highest speed the fan is still quieter than my GPU so hence not very noticeable

There is a fan but its a quiet fan

x 140mm(L)).Quiet fan is really nice, and it is also temperture controlled so does not spin when not needed

A couple weeks in and so far, it works fine... except for the obnoxiously loud, vibrating fan.

the fan works with the test button :p

The fan is silent.

fan making rattle noise as if broken and cant get any help.......

On the plus side, the PSU was easy to install (or as easy as any PSU is to install), it works fine, and the powerful fan does a good job of pulling hot air out of the case, assuming you install it with the fan facing the center of the case

The fan is very quiet and can handle everything that my custom built HTPC throws at it.

Particularly like that the fan only runs when needed.

Although, with the size of the power supply, I doubt you won't have other components that will have more than enough fan noise so that you will never know how good the low sound is of the Corsair

Noisy fan

Very quiet fan, comes with all the cables you could need

:) No fans running as fast as they can like the last one - it's awesome!

It's surprisingly quiet as well, tiny fans are usually pretty loud, but this one is quiet, but still audible

I have six SSDs and two graphics cards on top of the usual modern components, and the fan on this PSU is still silent.

And the fan in this Corsair TX650M, is almost silent

I purchased this product due to its price, efficiency rating, larger cooling fans, and the single 12V rail design.

It's powering 2 fans and my gaming video card quite well and looks stylish for those of you who care about that sort of stuff.

Fan started dying shortly before the warranty period expired

While it does cost a bit more for a Platinum rated power supply, the efficiency and the silent fan much of the time are great features, and this is a power supply that is going to be reliable and last a long time

This suits all of my power needs the adjustable fan controller is amazing this PSU runs super quiet

The fan is quiet, about the same low level as any modern power supply unit

The 500W:- Too large to accommodate a full sized GPU in this case... though not a knock specifically against this product, it is something to consider on smaller builds.- The Fan wobbles and makes a rubbing sound

it has averaged 80+% efficiency consistently - another factor in keeping it quiet, I imagine (higher efficiency = less heat = less need for a cooling fan)

These are very efficient, work silent (no fan during normal operation), and overall are very good for the health of your PC in the long run

This has a silent fan that only kicks on when it's warm and so far it hasn't moved from 30c even under heavy load

I can keep my PC on without having to hear the annoying fan

The fan works, and even with it

Everything works as it should, I find it very useful to be able to measure the consumption of the PC in real time, efficiency, each voltage and its temperature

Unfortunately, the product does not look as good as in the pictures (only leaving this because the flat cables it is shown with were one of my primary reasons of buying)

My power supply started smelling as if some electronic was burning after about a year

I actually prefer this over braided designs as it is much faster to reach a nice looking result - less need to tie things down

It works as except.

Works as it should.
