COOLER MASTER R4-L2R-20AC-GP Blue LED Case Fan

Comment:
LEDS appear nice,thats it! Customer support,they ignore you entirely !!! epic fail total garbage,wish i knew this prior to hand,wish i didnt purchase four at as soon as! total waste of money! bigtime! Id like to report in on these, own four above the last year and a half,sadly my very first 1 fail 9 days right after warranty,the the other 2 about a month later,and now the fourth one particular as im typing this is slowing down and making vibrations are rumbling sounds,i took apart 2 of them to locate that they use Extremely low quality grease,it gums up and becomes sticky causing the electric motor to operate overtime.Plus they have a low-cost sleeve bearing,BUT i knew that before purchasing them,i consider sleeve bearings are ok ,of course not as excellent as ball.BUT i have two other fans in my office computer that are sleeve bearings apevia LED 120mm and they are atleast twice as old,and they are Nonetheless going powerful,so it has to be the grease,and no you cant just apply distinct grease,if you peel the sticker off the front you may possibly feel your going to drop some oil on the shaft.Neglect about that its sealed.NO hole for shaft.And the fan is a press fit it breaks if you try to take it apart.So be forewarned these don't last!

*Pushes a lot of air, for being 2000rpm. *Not loud at all, I have six going proper now and I only hear slight air movement. *Comes with all the screws, cables, and so on... I've gotten some that don't... *I am not certain if its just me or my batch of fans, but two of them have diverse shades of blue. One half of 1 fan is a good darker blue, whilst the other half is a lighter blue. The fan above it has a lighter blue color all more than. If the fans had been the same color all about, I would give five. I bet its just my fans, and I really don't thoughts, but other persons may get the identical problems.

Each the fans I ordered do what they're supposed to. They move air, and they move a lot of it. One of them does so quietly compared to the 2 92mm fans I have running on my Hyper N 520 CPU cooler. They are also very very good hunting: The translucent black plastic combined with the LED's is a good touch and adds to the aesthetics of my case. That being said, one particular of the fans has poor bearings. It whines when powered to anything above 50% which is extremely annoying. I'm replacing each with fans that got better evaluations.Also, the three-pin power connection is incredibly brief. That was quickly fixed with extension cords. This will absolutely be an concern for individuals who don't have these extensions, hence the 4-egg rating from me. I gave it 4 stars because the one particular fan that is functioning perfectly and fairly quietly (Minus the 1 egg for brief cables). I expected greater top quality manage from Cooler Master, but I guess some bad merchandise always get via. Regardless, there aren't too quite a few complaints about undesirable fans, so you don't have to be unusually lucky to get a fan that isn't dysfunctional or DOA. I'm not going to RMA mine because I'm sure I can uncover some use for them. That, and RMA'ing it most likely isn't worth it both timewise and financially. Also, critiques say that CM consumer support is extremely unlikely to send new fans (Even though they say they will).

Bought these for my Corsair H100i and they're not "that" bad. Wouldn't recommend for radiators

Comment:
Good fan for the price, picked up two for my case and it matches the blue LED that the case came with, looks nice and fits my setup!

Comment:
It moves air like and cools my Pc like a champ! wouldn't propell my airboat The little lights... they aren't twinkling Clark

Comment:
nice fan really quiet , good quality for the price .

Comment:
Great fans, very silent. Makes almost no noise and is great for radiators.

Comment:
I am satisfied with these fans overall, but its a must to attach them to a low noise adapter or a fan controller. They are a good fan overall and push a good amount of air.

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:
-does its job-not blinding led-pretty quiet -moves fantastic amount of air none. have them on a fan controller.

i am satisfied with these fans, but its a must to attach them to a low noise adapter or a fan controller. they are a good fan overall and push a good amount of air. it gives off a nice blue light, they're a good fan but 2000rpm is a little fast and loud for my liking.

Comment:
very very good for the price and superior but the cooling is outstanding. in my situation i am working with a cm haf 922 with 8 of these in there and so far i have not 1 complaint. these function really great. fan grill with the cm logo??? and nicely the situation screws i wish had been superior good quality cuz mine preserve on stripping. these are pound for pound some the finest case fans cuz these aren't technically led situation fans they are el wire case fans which also implies they operate and last longer for each the bearings and the lighting.

When I see this on the site I think the LED will be more bright

Comment:
The cons are basically what you should expect so 5/5Cheap fan that moves lots of air. It's a lot brighter than what is shown in Linus's video. They provide a really nice glow, which when put in a computer makes it pop out a lot more.Definitely not a quiet fan, but it moves a lot of air. I have it as an intake on my tiny tiny mATX case and it dropped the temperatures by 5+ degrees (celcius)The gram does feel a little cheap, and you could probably easily snap it, but as long as it's mounted securely in a case it shouldn't have any problems

Comment:
Works perfectly although I wish Coolermaster would've made the cabling sleeved black instead of the weird grey translucent scheme since it contrasts with the black housing/shroud; fortunately, it's an easily fixed DIY.

Comment:
Bought this to replace a front fan that went on my AZZA Hurrican 2000 case. The Coolermaster definitely pushes more air and I am able to monitor the fan which I couldn't do with the stock fan as it was molex powered. The color is slightly different than the stock one so I might change the other one over to the Coolermaster and run them both of a split fan header.

Comment:
Used this fan to replace broken rear exhaust fan in my case. Works great overall (pushes lots of air out) and looks nice.Only issue is that the fan is slightly louder than the fan it replaced.

Oh you, Have a fairly tiny fan light, It fills my room with a soft blue hue; and when, I installed you,you ran actual rapidly and you kept items cool. high low, quite a few speeds you go... In you I wish I could depend... b@ng b@ng ch!tty ch!tty b@ng b@ng.. Is what my computors known as by good friends.... b@ng b@ng ch!tty ch!tty b@ng b@ng....Your new fan now is dead!! After 4 weeks, Immediately after only 4 weeks, After four weeks, Right after only four weeks... Alright sufficient sining! I installed this fan with the thought that it would be cool, quiet and reliable, like a Porsche! Oh no, I get a fan that makes my computor sound like an old clunker that was produced from an old wooden row boat!!! very affordable top quality, anticipated much far more from CM.

Decent airflow, quiet adequate, good packaging. LED isn't as bright as the old CoolerMaster fans. At 2000RPM, the fan makes a noticeable noise but nothing that would bother any individual. With the fan manage from BIOS, i can turn this factor down to 1400RPM and it still outputs a fantastic airflow with really low noise.

Comment:
Outstanding fan. Moves a lot of air. Runs close to 2,000 rpms. At 2,000 rpm it is a bit loud, but not poor. However, a single of my led's was a bit of a unique shade of blue. Not so much a con, but makes you wonder why. It is a bit visually disturbing...or was, havent had it for a year and now only one particular light performs. Regardless of the lights the fan still performs good. Fans are cheap so I won't complain too substantially, but I am disappointed. I have one more old school blue fan thats been operating for over 5 years now.

Comment:
Incredibly good. I like these fans Wish they have been PWM, but no matter. I knew that just before ordering them.

Comment:
They're quiet, and they DO move a lot of air. Blue LEDs aren't overly blinding or actually that major of a deal, even to an individual who doesn't want them. That's not to say they don't put out light though. They're not Practically 19db when at max. I haven no notion what RPM or CFM they're essentially at when it was measured, but I'd say far more like 26 or 28. That stated, they're not genuinely that loud either except when there's a bunch of them.Vibrates my side panel a tiny bit, producing it a bit louder, just because of it's energy and RPM. Not a enormous deal although. Purchased 4, one blowing in the side, 1 blowing out the back, and place two on a hyper 212+ in a push-pull config. Runs excellent and they're pretty quiet, but putting them at 90% is your very best bet.Deducted an egg simply because they're not as quiet as they say.

Comment:
Plugs proper in to the Mobo, adjusted efficiency in the BIOS and works like a dream. A lot far better than the stock fan that came in the Sonata II case. There have been no rubber fasteners for case mounting, fortunately I had an added set. Getting it's a case fan for exhaust purposes, the blue LED is wasted, but adds a faint glow to the back wall it is up against. Runs Quite quietly at low settings. The MOLEX adapter is one more bonus -just added to the collection of spare parts for other tasks on buddies/family repairs.
