Got 3 of these ones running in my system. Airflow-wise its great considering they're not very expensive. The only issue is the red one isn't as bright as the green one.

Pros: Pushes air FAST, high quality, excellent durability, cheap price (compared to some other 120MM fans at least)
Comment:
I purchased one of these almost a month ago, and it works amazing. For this price you can't go wrong with it. Plus it's very durable, and pushes air very fast. It arrived very fast, 4 days is great. Affordable and fast shipping - exactly what I'd except from NCIX :DOverall, 10/10. Plus the red LEDs on it looks pretty sweet.

I bought 4 of these to put in my Zalman z11 case. 1 at the top, 1 at the back, 1 in the front and 1 on the bottom. 3 of them are connected to the motherboard and the 4th is connected with a molex due to my MB only having 3 fan plugs + 1 cpu fan header. (I have an old MB - MSI X58m. Yes, it's ancient. lol) Even with all of them at full speed they are pretty quiet. They may not be the most quiet fans around, but for the price these are awesome. The red leds are not that bright, but it still looks nice in the dark. I would recommend these fans to anyone looking for some good quality fans that push a lot of air.

Iv bought about 7 of these over a 2 year period and some of them last and some dont.The last purcahse was about 3 months ago when i bought 4 and one is already dead but the other 3 are still going strong. If it wasnt for the cheap price on these id 100% go with another fan. But for the money these are cheap / very quiet fans. Just dont expect the best quality

Loved it so significantly I got much more, I overlook I have them at instances. Added them to my Coolermaster HAF 922 case which has related quiet fans, I just craved far more air and far more red glow!Bought 2 and placed them on my Coolermaster Hyper 212 Plus CPU cooler and relocated the fan that came with it to the bottom intake in my case.I consider I've become a Coolermaster fanboy ;~; they deliver. Coolermaster hasn't begun designing air conditioners yet. My case is super quiet, the only noticeable sound is the large 140mm fan on the top rated of my case, nonetheless quite quiet. I just turn it down to about 80% with my Scythe KM02-BK fan controller and then its like I just have a glowing red box next to me. Strong state computer any person? Buy it, and don't hestitate to get the other products I've talked about (the cpu cooler keeps my Phenom II Black Ed. x6 1050 at 28-29C idle 45C max on Prime95).

This fan pulls a great amount of air and is silent whilst it does it. I have them on my Corsair H50 and they cool substantially better than my silenx fans they replaced that have been twice as a lot cash! They appear to be quieter as well! In truth when i initially installed these onto my comp and turned it on i freaked out thinking they had been broken because i didn't hear the fans. To be picky the LED's are a tiny bit dimmer than i thought they would be they nonetheless light up my case and leave a good red swirl on the fans so its not so a lot a con. I had to get these elsewhere mainly because newegg only had a single in stock at the time and i required two :(

Cons: LEDs aren't as bright as my other fans but not bad.

Pros: Pretty quiet. I use them with a fan controller and they're great on the Low setting. On the High setting, they can push through a LOT of air.

These certainly pull their share of air. Good red LEDs go great with my CoolerMaster Storm Scout and ASUS Rampage III Formula setup. Sounds like a Learjet readying its engines for takeoff. No exaggeration, I can hear them more than my speakers on full blast. It's like being in a wind tunnel. I'm very dissatisfied with the noise level of these fans. The pitch of the noise is specially annoying, as periodically it tends to sound like a tornado siren. Possibly these could perform for you if you plan on maintaining your rig underneath your desk, but for those of us who don't have that option, I urge you to keep away from these fans. The noise is utterly obtrusive; you locate oneself unable to pay consideration to something else.

I've bought 4 of these already, and they are nonetheless in excellent functioning condition immediately after virtually a single year. I just purchased 8 far more of these fans two days ago, so I am waiting patiently for them to arrive. These fans moves a lot of air, and noise level is whisper quiet. The led are bright, but not blinding bright which is fairly good. It's actual red led, and not these fake red-pink led fans. The fans screws are silver... they should of came in black.That's about all the cons I could come up with other than the fans not becoming totally free. I got a HAF 932 case, and I have 4 fans on the side. When these other 8 gets right here I'll place 1 on the bottom, 1 on back exhaust, 2 on prime, two on my Hyper 212+, and two in front.Quite satisfy with this item.

Comment:
I bought a couple of these to replace the aging yateloons in my computer case. The yates have been running almost 24/7 since the first day of build. There is physically nothing wrong with the yates as of the moment but I just needed these as spares just in case.I have 6 yates as intake-exhaust fans in my case as well as 2 more strapped to a hyper 212. The 2 on the cpu cooler are controlled by the motherboard while the other 6 are on a thermaltake fan controller. I installed two just to test these out and those already made a noticeable INCREASE in fan noise. Airflow increase substantially as well but as of the moment, the yates are doing a good job keeping everything cool. At the lowest fan controller setting, CPU temps run in the high 30's to low 40's. (readings by CPUID HW monitor and speedfan). This is during normal usage)Since these offer a substantial improvement in airflow over the yates, then I'm pretty sure they wil do a decent job later on. Like I said, these are just backups should any of the yates fail after 3 years of continuous operation

Very good airflow, good RED LED's I paid a little a lot more to get CM brand, but one of the pair i got in fact resonate at full power. I know have the one more than the GPU not powered, and the one over the CPU at about 30%. Want i would have bought distinct ones.

They are black with a red LED which matches the Cooler Master Scout case very properly. They look to move air around Incredibly efficiently at the expense of sounds. These are a lot louder then my stock cooler master fans and I am not sure how to quiet them down. I am reading the evaluations and everybody claims they are whisper quiet, but they are def. not. I would enjoy for someone to explain how the hell theirs are whisper quiet...

Really quiet fan, good air flow, nice looking red light (four of them). I expected the light show to be more pronounced, based on the picture, but it is actually quite understated - in the dark only the four light "threads" are visible, nothing else.

Perform well and can push air. It's not the quietest fan, and there are other fans on the market that can perform better. However, for its price, it is a good buy and I would recommend it to others and am willing to buy it again.

With an extra 20% off on these fans through a Newegg unique, couldn't go wrong with the price. LEDs are bright and even with a filter over the front of the case, they nonetheless shine thru. Extremely pleased with the SickleFlow line. I now have 3 total of these fans in my case. Wires could be longer, but it does come with 3pin to 4pin adapter, which I am now using till I get a fan speed controller for these bad boys!

Dead silent as long as absolutely nothing is too close to the blades, pushes a lot far more air than expected, led lights look good. individual issue, but cord wasn't extended adequate to attain the mobo fan plugs. I reduce a hole in the top of my case to place this fan in because I was going to be crossfiring quickly and was worried about heat. I place this in and my complete case temp dropped 12C instantly. in brief, this issue is a beast. Newegg offered once once again :)

Very Quiet. Perhaps the quietest fans in my program aside from the PSU. I purchased these suckers to replace the blue led fans that come with the Antec 1200 as they had been loud and I don't like blue that considerably ;). These suckers move twice the air with half the noise of the fans they replaced. They are bright but not obscene. I've bought these in the previous and in no way wrote a evaluation, but the ones I have have been running for over 1.5-two. years and not shown any signs of stopping. Not free and they don't dust themselves? I enjoy Coolermaster fans and circumstances.... acquire these you won't regret it.
