COOLER MASTER SickleFlow 120 R4-L2R-20AR-R2 120mm Silent operation Green LED case fan

Comment:
Got 3 of these ones running in my system. Airflow-wise its great considering they're not very expensive, highly recommended if you don't want to spend 4x the amount on a different brand.

Work well, love the green colour

Comment:
Really bright among blue and red. I have all 3 colours and green stands out . the least bright one is red.Now I will explain the con, the bearing on the fan needs to be lubed or it will make squeaky sounds in the long run especially running at low RPMs. The sound is annoying and sharp so just to give guys a heads up, but at this $ you guys shouldn’t complain much lol.

Fantastic airflowLow noise levelSubtle LED lightingthree-pin fan plug, with Molex Ɣ-pin) adapterMarkings show fan blade rotation direction and airflow direction A small much more costly than I hoped. Worth it.Came in an open box. No damage, all the components were there, but I don't want to spend full price tag for a returned item. No open box discount :( three-pin fan is superb, some I purchased previously have Molex only. This is the ideal of each worlds."Quiet" when referring to fans is subjective, nonetheless this is exactly what I was looking for and exactly what I anticipated when I purchased it.Fan blades are type of a translucent black, which helps the green LEDs look a lot more subtle. Some clear case fans with bright LEDs appear as well flashy and I did not want that. I have a fan filter on it also which subdues it even more. This is on the front of my rackmount server case, so I wanted some accent but not the flashy gamer-case BLING sort.

THEY ARE FANS, THEY BLOW AIR LIKE ADVERTISED. BLACK WHEN NOT Operating AND DARK WHEN THEY ARE Operating Appears Good IN AN ALL BLACK CASE, THE CM ELITE 430 NO SPEED Manage LIKE ANTEC'S THE BLACK FANS Really should HAVE BRIGHTER LED'S FOR THE GREEN TO Genuinely SHINE three STEP CONTROLLER AND BRIGHTER LED'S THESE FANS WOULD BE Great!!

Comment:
Incredibly nice fan. Bright green LED in each and every corner that reflect off the 9 sickle shaped blades. Extremely quiet. Appears to collect much less dirt than common fans. None yet!

Comment:
Lots of airflow with 12v source; LEDs are vibrant adequate to accent rather than distract; effortless installation; top quality-built things. Only "silent" when plugged into motherboard "sys fan" port. When making use of integrated 4-prong 12v adapter wire straight to 12v supply, fans provided a LOT of airflow, but unbearably loud (I could hear them from 40 feet away in a different space as if ). Not ideal for a HTPC (e.g. my application). Naturally, plugging them into the MB and that made them quieter, but disappointing due of the quantity of airflow lost with the power lower. Airflow and quiet operation had been my two biggest elements when contemplating these and was somewhat disappointed by the "Features" description stating "strong airflow" and "silent operation". They have "okay" airflow at greatest when plugged into the MB and lots of airflow and noise when on 12v power so it's a lot more of an either/or. Would have been good, because I have 3 HDDs, video card, 24x DVD burner, and i7 processor I will need to take heat from.

Pushes a great amount of air, quite quiet in a HAF 932 case. The green LEDs are not overbearing as it is produces a nice green windmill/shuriken design as the black fans spin. The fan is not an opaque black, but a nice translucent black that offers a sleek, polished look much better than solid black stock fans. This fan also has much more blades on it than other companies, which assist "slice the air" a lot more efficiently to generate much less noise though creating as much airflow. None so far, but if you want your fan blades to appear green as well, you may want to appear at GELID fans with green blades, but they have white LEDs. I have two of these installed on a Corsair H50 in a push-pull configuration. The green LEDs produce a good glow out the back of the chassis, and also a great green glow on the heatsink/processor region. At about ű each and every, be positive to strategy out how several you want ahead of time. If you're going for a green color scheme, you only require two or three (placed in different areas of the chassis) to give your rig a great glow with out creating your rig appear like a nuclear reactor.

Inexpensive. Lights are bright enough to light case nicely, but not overpowering. Moves a excellent deal of air with no significantly noise ࿡+ CFM @ ង db). HORRIBLE LIFESPAN AND/OR Quality Manage.I wish I could give eggs. 7 fans, 7 failures.I began my computer construct by replacing all 4 of the stock fans with these, given that they move a great deal additional air ࿡+CFM) and much more quietly (ងdB) than the stock fans ࿍ CFM @ 26 dB).The initially fan died about two months after installation. -1 fan. ů S&H to replace it. Replacement died two months right after install. No warranty for replacement. -2 fans.Second fan died about 3 months right after installation. -3 fans. ů S&H to replace it. Replacement died four-5 months right after installation. No warranty. -4 fans.Third fan went robust for a couple of months, then began slowing down, then finally stopped. -five fans. One more ů S&H. Replacement died a month immediately after installation. No warranty. -6 fans.Fourth fan created it 1 month past the warranty period before it gave up the ghost. Turn on the comp one particular morning and BZZZZZZZ- WARNING: Method Fan Failure! (followed by lots of option language). - I purchased 4 of these fans, and replaced three of them beneath warranty through the first year. The fourth fan died a month after the warranty lapsed. All 3 replacements failed within a handful of months. Out of 7 fans I've owned, 7 have failed. Five failed within the very first six months, one inside the first year, and 1 in only 13 months.That is, bar none, the absolute WORST quality control I've ever even HEARD of, let alone had the misfortune of experiencing.Considering that I ended up spending 170% the retail cost on every single a single, which includes S&H to RMA the 3 defective units, I would have just been much better off obtaining a higher top quality unit in the first location. CoolerMaster doesn't make the quietest or the most effective fans. If you want a quiet fan, just commit the little bit of additional $ now on the ones that come with the "Ultra Low Noise" adapters. You'll end up spending about the very same quantity anyways right after RMAs, and you'll get a vastly superior fan with a vastly superior warranty Ɩ ye Manufacturer Response:Dear Valued Client - We sincerely apologize for any inconvenience. Please speak to us through the Live Chat link beneath so we can get this rectified for you under warranty. We will replace the four fans.

Incredibly quiet for a 120mm. Excellent airflow. I have 7 in my mid tower and it is not loud at all for what i have in there. The LED lights are excellent, in the picture it looks like they dont light up nicely, but they do.Keeps everyhting really cool, I place my hand more than the exhaust from time to time, barley any warm air. And sence the Ɣ) LED lights point at the fan blade and not at your face makes it fantastic if you wanna sit back and watch a film. NONE I will under no circumstances purchase a different fan than these. Best ones in my opinion.

Comment:
Lots of airflow, had space to add one in my HAF 932 Possibly mine is faulty or a thing, but there's absolutely nothing whisper quiet about this . Its louder than all the other fans in my situation combined, and the HAF 932 comes with fourƓx230mm, 1x140mm) if you dont mind the noise, this fan looks nice and does its job exceptionally

Wanted a green LED fan with high CFM. Specifically what i wanted, GG Cooler Master!I dont know why so a lot of folks say these are loud, i have four of them in a NZXT case, 1 as an intake, 1 as an exhaust. And 2x on a Zalman CNPS10x Flex CPU cooler.They are noticeably quieter than the fans i have on my Antec DF-85, and the CM R4's that are on my Megahalems cooler on my other i7 technique. I really feel as though labeling these as "Silent" is a bit of a drag. They are not silent, but they nevertheless Extremely quiet for a 120mm fan thats spinning at 2000rpm and producing 69CFM. All in all, a excellent acquire, not only would i obtain them again, I did obtain them once again! I would also recommend them to anyone requiring a high CFM fan that doesnt make extremely a lot noise.

For the power to noise ratio it's fairly good compared to others of the similar size. I'm employed to computers tiny to or no noise at all being a casual gamer. When my personal computer died I purchased a new comp from NewEgg and the stock fans were so loud I could be three rooms away and still hear it clearly. So I purchased this a single installed with push pins from the earlier one no issue and noticed the difference initially time go. Admitly I know the majority of the noise level came from the air becoming sucked by way of the side panel protective dust guard but its a fantastic relief from what it was. Pins had been a tight fit on the 2nd were abit tight. Otherwise no massive deal, the plastic seemed a small fragile in the course of installation but held up fine. If any point so far could be known as a con it would be the light on the green a single is not as vivid as the blue one particular of the similar brand. Although to its credit it is really crisp. So I envision the red is abit dim as properly if your making use of a complete size case. I most likely ought to have purchased the red ones seeing how clear these are. But thats all personal taste.

Aren't super vibrant. Give off just adequate light to accent the fan. Also they are really possibly the quietest part of my setup. Move Plenty of air! Aren't super vivid if that's what you're looking for

Looks wonderful and is incredibly quiet till you block it (put my hand in front of it and it sounds like a hairdryer, it moves pretty much as substantially air as one too) I now have my core i5 processor (not oc'd) operating at 28 degrees celcius though gaming (fallout nv @ ultra high setting) and thats with the stock intel cooler on the cpu (downflow cooler) The shiny sticker in the middle looks wierd, not a large dilemma, but with a smoke black fan and green LEDs, what was the thought behind that sticker? I have it in a raidmax smilodon extreme black case and the light from this fan perfectly match the green lights on the case. My friend is running very same case/cpu and is operating about 48 degrees celcius under identical load. I also did alot of wire cleanup inside the case and before I did that it was running about 36 degrees celcius.

Comment:
add two on my case. cpu temperature dropped from 48c to 43. (i7 930 ʃ.8) Loud... I can hear massive noise... Effectively, if u dont thoughts it, just acquire it.

Pushes a LOT of air, even at the lowest speeds. It isn't loud whatsoever, I'm guessing the people today saying this have it operating at 80-100% speed. Which I can't picture why you would require it that fast when it pushes so considerably at low speeds. I don't hear it over the rest of my pc. Possibly you could if the rest of the PC was totally quiet. Essentially its quiet and pushes a ton of air, what much more can you ask for out of a fan. I installed 1 for intake at the bottom front of my case (replacement for a poor quality case fan) and it dropped my OC GPU temp a couple degrees. This factor pulls far more air than all my stock case fans combined in all probability. None. There is nonetheless time for some thing to go wrong as I've only had the fan for a small over two weeks, but every thing is wonderful so far. If you need to have a LED 120 fan that pulls a TON of air, here you go.
