COOLER MASTER SickleFlow 120 R4-L2R-20AR-R1 120mm Silent operation Red LED case fan

Comment:
This fan does a excellent job moving air into your method. Looks good and does it's job I did anticipate LEDs to be a tiny bit brighter and it is a bit louder than I had hoped for but it does a good job maintaining everything cool.

I've purchased four of these so far, two of them running push/pull on my Corsair H50 cpu cooler. Good and quiet, move lots of air, nice lighting, I mean what else could you want? Oh and they're a extremely slick, polished plastic, so they don't pick up dust as simple. Excellent! None

Just arrived. Instantly plugged it in with complete energy and...1) It's whisper quiet (don't know what's wrong with some of the other reviewer's fans).two) It glows a best blood redō) The fins are a translucent, smoky gray and the LEDs are at just the proper brightness; offers the front of my case the red glow I wanted, but not so bright as to notice unless you're looking at the case.four) Outstanding, highly effective airflow. Really cool.5) The direction of fan rotation and airflow are clearly marked with arrows on the left side of the fan.Of course, if this fan starts squealing or rattling in the coming weeks I'll write an additional evaluation. 1) Comes with silver fan screws, why? Really should be black.2) The screw holes aren't pre-threaded! (I'm going to use silicon fan mounts, but what if I wasn't?!)three) When combined with the Silverstone FF121 120mm fan filter the airflow is significantly cut down. Like switching a bigger fan from "Hi" to "Low" skipping the middle setting. But that's the price tag of possessing a dust-free system. I'm working with this as the front HDD fan in my Cooler Master Elite 335 Chassis. I've modded the side panel of the chassis to close with my Cooler Master V8 120mm Rifle CPU Cooler sticking out a small, like an engine popping out of the hood of a drag auto, and the V8 CPU cooler glows the identical red colour!

I installed two of these fans in my Storm Scout today and right away saw a substantial drop in temperature. My CPU was 5 degrees cooler on typical and my molten-hot GTX 470 dropped ten entire degrees when idle. The fans don't fit perfectly into the Storm Scout. With two of these fans operating, it can get fairly loud in a quiet room. I would fully advise these fans to anyone who desires sufficient cooling for their Pc. While they are really loud, it's not horrible.

Completely blows my original case fans out of the water, wonderful airflow, sleek LED appear, fantastic addition to the side panel of my Coolermaster HAF 922. LOUD. I at present have to unplug it to use my computer as a Media center in any way (netflix, hulu, watching random motion pictures) unless I am sitting suitable at the computer system near the speakers. I strategy on acquiring a fan controller in the subsequent handful of days so hopefully as soon as I get that all set up and slow it down slightly the noise level will drop, will update my critique when the time comes for the Fan controller

i like it the big red machine, moves lots of air at a decent sound level, couldnt almost hear it,

Comment:
Great fan, running fast, quiet, under 10$ you cant go wrong. Fit well but the LED not so bright, you barely see trough glass and dont illuminate inside the case enough but the air get out very quickly.

Comment:
Looks and efficiency. They are great medium range fans. I use two of these for push/pull on my Corsair H50 and they perform just fine. They are not too loud by any signifies. All about good fans. None

Comment:
The fan moves alot of air, and the sound to be sincere i don't notice something various, its a small case fan... they don't even make substantially noise to me, but to some i guess they could. If you're looking for a vivid LED this is not your fan, it has a great display but it isnt the brightest to light-up a situation in red. If you want a good sleak stealthy red LED color to your case, these are your fans.

Comment:
These fans are great and they are very cheap. The airflow is amazing for the price you pay.

Comment:
Wonderful fans. Fantastic Airflow. LEDs are visible but not also vivid. On total speed they are a tiny loud (not the worst i have had though).

Comment:
Great fan for the price considering it moves a lot of air and its quiet. Its great when used as a case fan or heat sink fan.

Comment:
it's red, it spins, it moves lots of air that's all i need right? would recommend to everyone

Comment:
Great fans, very silent, comes with cable extension and silence adapter. Makes almost no noise and is great for radiators.

Comment:
These are fantastic fans. They move a lot of air, they are quiet, and they appear fantastic. Comes with 3 to four pin adapter and screws. None. The LEDs aren't overly bright, that could be a pro some some people and a con for others dependent on your opinion.

Whisper veryNice red glow (so tired of "blue-everything")Go Nicely with my HAF XActually helps the overall performance of my Hyper 212+ Not Free? Used two on my Hyper 212+, man these items move a lot of air.I intend to acquire a fan controller (or make 1?) so I can adjust my fan speeds and quiet them down a small - but it's nothing at all that bothers me, it's nevertheless quieter than my final setup.

Comment:
It Blows Air Combined with the NZXT Sentry-2 5.25" Touch Screen fan controller it sounds like a truck anything about the Fan controller makes the actual Moter make noise in the fan itself as I can stop the fan with my hand and it nonetheless hums. the sound is not there when connected straight to the motherboard Great Fan just dun use it with that Fan Controller if you want quiet Opperation, Also tried Green of the identical product line led fan it was quiet, and blue was in between the two.(Product Overview for Green and blue Fans of this type here also)

Operates properly, looks astounding, moves a very good quantity of air. A little bit also loud for my liking, so i ran them by way of a fan controller so I can maintain them a little quieter. Bought 3 of them, all of them worked fine.

Comment:
Moves a lot of air, Not the most silent fans but undoubtedly not the loudest. Pretty much the best Black plastic red LED fans you could obtain at the time Bought five of these in Sept 09' and one particular died immediately after six months, an additional following three more months, and now one more after a year n 6 months. When they have been new the did a great job of moving air. i cleaned the fans often generating positive there wasnt any huge buildup. When they do begin to fail you'll get a horrible vibration noise in your rig that will at some point go away as they warm up. I was expecting a little additional life out of these fans but for 9 bucks i guess i got the most out of them.

Comment:
The cost was proper and it pulls a lot of fresh cool air in to the front of my situation. Red LED looks really awesome. Fan is a lot louder than I expected given the specs on this fan. Maybe it is far more to do with the situation than with the fan, have not had time to take it out of the case and test it. I have it mounted in the front of a CoolerMaster Elite, probably all that aluminium mesh is amplifying the fan noise?

Comment:
Moves lots of air. LEDs are not overpoweringly vibrant. Good price tag at 8.99. Not so quiet the moment they are installed...pushing lots of air by vents and grills tends to make noise no matter which fan you use. I have a fan controller, so was able to tone then down some. At total energy they push a ton of air, with five of these in my cosmos it felt like a vacuum.

Comment:
Bought 2 of these for my CM V6. two of these are quieter than the stock fan. They also move more air. Dropped cpu temps 3-4 degrees. None so far. CM HAF 932I5 760 (oc three.6)EVGA P55 For the Win 200WD Black 1TBEVGA GTX 570 SCCM V6 Ultra X4 750 watt

Comment:
They're low cost, have three pin connectors with molex adapters, they aren't also bright and they have fantastic static pressure. They're quiet and so far (oldest is over a year old) they last....Not as great of top quality as my significantly older antec tricool led's but for the price tag, not bad. (paid 20 a pop for the antecs) It's a fan? It's a FAN!

Comment:
Pulls lots of air, red LEDs N/A In my prior review, I said these are quiet. Nicely, they are not up against anything. I place these on the window in my Cooler Master Storm Scout, and mainly because of the design of the vent in the window, they get a somewhat loud hum when operating. No biggie, I just bought a fan controller to slow down the speed and make them quieter. They also pull alot a lot more air than the fans that came with the situation, at least two or 3 instances.
