I had not so pleasant experience with this box. It worked sort of Ok for a year or so. One day it just decided to spin the fan so hard I was amazed of the noise that came off it, then it shut itself down. Thenceforth, it would not power and stay for more than 15 minutes the next things is that it shuts itself down with "Thermal Tripping" error which which was an indication of overheating. I called Intel, they send me details how to send it back for Warrant replacement. But I missed the fact that they asked me to remove accessories which actually included opening the case and take out the SSD and RAM. So, anyway replacement arrived but does not power up only green light blinking. When I contacted Intel they say or there could no RAM, I should install the RAM and SSD from the older. This was such heart breaking news. Long story short, I have lost 1TB SSD and 32Gb RAM. It is such a terrible setup, how does intel expect every end user will have the knowledge or skills to open the thing and take out the guts? So, anyway if you have and encounter a problem and that you need  warranty replacement, be aware of this. Thanks!

The air flow and the noise is greatly reduced! But there is still a little weird noise from this fan.

Having issues rating this. After one day, one of the two horrizonal fans started making a clicking noise. After looking it up, it looks like fluid dynamic bearings work best when mounted vertical, not horizontal. The fan that is still working great and VERY silent.

It is already making noise and i am afraid i have to replace it already.

I have had this power supply in my self-built desktop for many years and it has been rattling for at least 2. I thought it was hitting a wire but I actually think it is a bad bearing of the fan. I love the variable fan control and the fun colors and lights but I will not be buying this brand again.

Fan squirrel cage started squealing after just a few months use at work 8-10 hours a workday. Worked well until one day it it started making a horrific noise. Turned it off for a few minutes, then back on, and noise disappeared; 5 minutes later, however, the awful sound was back.

Mine went through death throes after 4 years. During that time:
- When I got it, it had noise due to air chop. The center of the fan blade was oval instead of perfectly round, which I believe caused this.
- After 3 years, it would make a rattle like it has a bearing issue when pointed straight ahead.
- After 4 years it started squealing.

I had vacuumed it and periodically opened up the case and throroughly cleaned it out during its lifetime.

I opened up the motor and found plastic ties inside that had become brittle and snapped, looking as if heat had affected them, along with sheiling tape peeling off some of the wiring. I would not advise trying to open up the motor for servicing, you may never get it back together safely for these reasons.

That said I'm buying another. I need something that can quietly move a lot of air quietly and this does the job. I just wish the quality was a bit higher.

The fan worked fine for about 1000hrs continuous. It was relatively quiet but now it is making quite the noise, sounding like it is on its last leg. It sound like the sleeve bearings are going south. Not sure how they came up with 3500 hour life rating. I should note that I am using it to vent a camper trailer battery box, so it is exposed to temperatures from freezing to 100F. I will get a ball nearing fan next time instead, hoping the bearings last longer.

I love the way it looks and it worked fine for about a year but then in the process of moving I'm not sure if it was jostled (it was in the original box with all the styrofoam and everything) but it started making this horrible buzzing sound. After that it barely heated anything and I was a little afraid it was going to give me cancer.

This little fan is more sturdy than I expected. I'm even more impressed after the fan was accidentally turned on while carrying it downstairs in my laundry basket. The fan head was a little warm and I thought it would have burned out the motor, but it still works great!

::EDIT::
This thing got LOUD.  As in, there is this ticket sound like a cable getting clipped as the fan spins, and I cant get it to go away.  I've contacted support and received no response in over a month. It's just TICTICTICTICTICTIC as the fans spin.  It still does a great job cooling my laptop, but this noise is unacceptable for owing it less than 5 months.

Purchased for my MSI GE60 laptop.  Laptop has a side exhaust vent, and it fits great.  Lowers my Temps by about 20 which lets me get quite a bit more out of my 660m via MSI's Afterburner software.

It's a bit loud when running at full speed, but if you use a headset or earbuds when you game, you won't hear it.

I do get a bit of a rattle sound when I started using it, but I put a small piece of folded up paper under the cooler unit to prop it up a little bit and the sound went away.  For the price, this little thing is amazing!

Had this fan professionall installed in a bedroom. Hard to use this fan at night because it puts out this strange, intermittent clicking sound. Not a constant click, there's a sort of off-and-on rhythm to it. Doesn't wobble, just clicks. Like the ball spinning in a roulette game. At every speed. Really annoying.

Let me preface by saying I am a fan fanatic.  I travel with my own box fan, which gets placed a foot from my face in hotel rooms.  In my bedroom at home I had an industrial shop fan which blew wonderfully loud and hard, like being in a wind tunnel.  However, it was an eyesore to have in a bedroom, according to my wife.  Personally, I value performance over presentation when it comes to fans. Sadly, after 8 years, that fan died, so it was time for a replacement.  The wife insisted this time I find something more visually pleasing.  I searched on Amazon for awhile and came across this fan.  It had a VERY high price tag, but it looked nice and the reviews stated it was loud and blew incredibly hard.  I had high hopes.

First off let me say, I did not find it very easy to put together by myself.  Also, once the front grill is snapped on, it is EXTREMELY difficult to get back off, which would make for very troublesome cleaning the blades and interior down the road.  I put it all together, plugged it in and waited for joyful bliss to ensue.  Wrong.  The fan did make a wonderfully loud fan/white noise sound and WOW does it blow hard!  Unfortunately, it also made other uneven annoying grating noises.  For a great sleeping experience I want the loud even white noise.  These other noises came and went and were irritating.  I hoped this was just a bad apple and requested a replacement from Amazon.  (BTW, taking the fan apart and reboxing it was not remotely easy.)

When putting the second fan together I decided to go piece by piece and test the motor out each step of the way while putting it together to be sure it wasn't an error on my part of not tightening something enough.  The motor on its own ran perfectly smoothly, but once you started attaching pieces, there came the noises.  Unacceptable.  I think if you used rubber/vinyl washers/grommets when putting the nuts and bolts together it may cut out those sounds, but for $258 I didn't feel like I should have to go out and buy additional pieces and hope they worked, plus I worried that as time passed, these sounds would just get worse.

Also, I found the small pull chain used to turn it on and off and cycle through the speeds not appealing.  One of the fans came with a piece of string to tie on to the chain to extend it.  Literally, a piece of string with a small piece of metal on the end.  Very unattractive.

In the end I returned both fans, which each weighed 75 pounds and came in huge boxes, so the repacking to return wasn't easy, and I went searching again for another fan.

I've had the fan for just over a year now. It never moved much air; even on high you didn't feel it unless you were right up against it. For how loud it is, it should have been a lot more powerful. That aside, it just completely crapped out on me and no longer works at all. When it died, it had a pretty bad odor coming from it and was hot to the touch. I feel like if I hadn't noticed it quickly, it would have started a fire. Recommend you look elsewhere for a better fan.

Well I've had this fan for almost a year now I initially loved it the price was great it looks awesome and it's very quiet and airflow was good. But now every time the fan starts up it starts squealing really bad for about a minute like a bearing or something is going on it I'm going to have to order another fan before this one dies

Ive had the fan installed for 4 months, and the first 3 months it ran without issue. Now is makes an irregular metallic ticking sound, almost like some ball bearings are worn out. I hate it and now have to buy a new one and pay for another install
