4 Years of life from 3 I bought 1/19/2018 9:44:21 AM

Pros: nice clean white

not very loud for running at 12v, there are louder ones out there

Cons: Even though I had a good experience using these fans, two of them had stopped working, I had tried to re lubricate the bearings with some success but the motors of the fans would get hot. When the slow down they have a Whirring noise that gets more Tick-y as the fans slow down.

Overall Review: I don't think that the quality of the fans was bad, and it was just the age of my fans since it took them so long to stop.

Great fan, quiet-ish, durable-ish 11/21/2017 7:01:02 AM

Pros: Moves air very well - you could dry your hair with one of these. Not loud at all - excellent airflow for the noise it puts out. More affordable than some fans, and good quality for the price. White fan blades look great in my case.

Cons: Not silent fans, vibrate a bit. I killed the noise with sound-dampening fan mounts.

After one year running 6+ hrs a day, the bearing went bad on one of the four fans. But nothing lasts forever.

EDIT: after 5 years, every single NZXT fan I own, including the one I purchased to replace the one with the bad bearing, is rattling, buzzing, or having trouble spinning. I bought these to match the Fractal Design fans that came with my case. If I had it to do over again, I'd have purchased the FD fans, because those are all still 100% operational and have always been near silent.

Overall Review: I run four of these in conjunction with the two 14cm fans that came with my Fractal Design Define R4. These are the perfect additional/replacement fan for that case, since they look a lot like the stock fans (though they're a tiny bit louder and move much more air).

Works well, until it doesn't 1/23/2016 9:05:27 AM

Pros: Super quiet operation
Strong air flow
Ease of installation (or removal)
Common power adapter for case fans
Rifle bearings are supposedly more durable than standard sleeve bearings
Helps keep my system running under 40ºC, even during heavy use in the summertime.

Cons: One of two fans started to fail after ~18 months

Overall Review: I purchased two of these fans in September 2014. While both are functional, one now makes noise at startup, or intermittently while running. A smack over the motor usually quiets it back down. I can't really complain too much for $9.

This is the shortest life span I have ever seen on any case fan, and I have been building my own machines for almost 2 decades. It's probably a one-off issue, but I rated with 3 stars because of this.

Decent, for awhile 12/11/2015 11:44:03 AM

Pros: The fan moves alot of air. Regular fan without LEDs. Connection wire is long enough to allow you to use cable management for it.

Cons: Have had 2 of them start to fail after about a year but luckily NZXT replaced them without any hassle. The bearings start to go out and the fan just runs at a snail's pace while being extremely loud. As a sidenote, the fans that began to fail were mounted horizontally, mounted for exhaust on the top of the case

Junk 12/3/2015 9:39:18 AM

Pros: Look decent. I like the white and black color scheme.

Cons: Run loud and build quality is highly suspect. I bought 7 of these to put in my case and have had 4 fail within a short amount of time. They suffer from a multitude of problems including the fan rubbing against the shroud, rattling, slow turning, and eventually complete failure. Would definitely not buy again.

Overall Review: Would definitely not buy again.

It's a Fan. 8/27/2015 2:23:35 PM

Pros: Honestly. It's a fan. It blows stuff. Kind of like my aunt with questionable morals.

Cons: If you want a fan to match with a white NZXT build please note the white from the fan is very creamy in comparison to the white fans that come bundled with the case. My only complaint.

It is also not the same fan design. Once installed, you can barely tell though.

Overall Review: What more can I say? The fan sucks and/or blows.

sensitive to shocks if facing downwards. 8/22/2015 10:14:11 PM

Pros: Bought 4. In use about 2 months now.. These are nice, quiet. seem to move a decent amount of air.

Cons: One broke. If you have this pointed down, gravity can take its toll. A slight shock to the case or fan, or getting your hand in it while in operation can break it. As I was working with it, my finger slipped into the fan and the result was it disconnected the part of the fan that holds it in the center. Result fan cant spin without scratching the black mounting. You might have had this happen in other fans, where the blade part becomes unglued from the rest of it. and wiggles in and out from the center. (it basically will get loose) Too bad this happened so soon. Call me mr butter fingers.

Overall Review: I bought a spare. I also don't really need as much cooling as I thought so I dont really care. But I will just buy cheaper fans that cost half next time rather than these. I mostly wanted them to match the case I was using (also NZXT) and they are indeed quiet fans.
