COOLER MASTER R4-L4S-10AB-GP Blue LED Case Fan

Comment:
Use as a top exhaust case fan. Completely silent at low speed. The LEDs are so bright that light up my case perfectly. Note: It comes with silver color screws and wire. the wire is a little bit short (About 9 in), which can barely reach the sysfan socket on the motherboard.

Comment:
they are nice fans, not the best, but work well for the price, the clear cases are nice as they fit well with the rest of my fans, and they aren't very loud, would and probably will buy again

Comment:
Seem to be good quality fans. Plastic feels durable. Comes with mounting screws and power connector adapters. Doesn't move a crazy amount of air but they are completely silent. Got a price match so they were as cheap as you could expect to find a 140mmm case fan!

Comment:
The 140 mm is actually almost dead silent. Nice bright blue, but not over powering. Cheap fan power untill I pick up some Wings.

Very good ConstructionGood Vibrant Blue LEDSExtremely QuietFantastic Air Flow Cost appears just a tad higher compared to 120mm models. These fans are incredibly quiet. Note, they are not silent. If you have one particular fan you might or might not notice any noise, but if you run numerous fans expect to start to be noticeable. I have two of these and two 120mm fans in my CM Scout case, through the day you have to try to listen for them, but at night when the residence is quiet they have a smooth calm hum. I am extremely tickey when it comes to fan humm noise, but no a single ought to have a lot situation with these.

decent airflow and pretty quiet.average quality and price

Comment:
-good air flow-effectively made-quite quiet -I purchased Cooler Master specifically b/c I wanted it to match my three 200mm cooler master fans but the leds are a substantially lighter color& I do not like the way it appears in my case. I attempted a different connection encase there wasn't enough energy for the LEDs but that wasn't it. Fantastic item more than all but I currently threw out the box devoid of considering so no return just a ผ loss here

Comment:
Pretty, glows. Seems fairly sturdy, accidentally stuck finger in the blades twice and none of them snapped off. Hardly appears to move any air. the fan next to it is a stock 120mm 9 blade fan. I accidentally broke off 1Ǚ of those blades, and it nonetheless moves WAY far more air than this a single. Would not advise, get a fan that moves more air.

Comment:
Wonderful solution moves a lot of air although remaining extremely quiet. Blue LED's looks incredibly good in my new Thermaltake Armor + case. None at this time, utilized them for about a month now without any issues. If your seeking for a low expense fan that is rather and moves a lot of air this is the fan for you.

Nice Blue LEDs preforms well cant get the screws to go all the way it so its loose in my case despite the fact that it doesn't jingle or anything so i don't know if its a difficulty performance sensible its just annoying and unsettling it really should be in a position to screw all the way into a Cooler master case

Comment:
Bottom line: would purchase again, but not for anything mission critical.

Comment:
I'm amazed at how quiet this fan is. It's obviously more silent than powerful but the specs are great for a 1000rpm fan.During installation the screw holes were a little too tight for comfort. The frame was twisting from the torque so I stripped one of the screws due to this and had to remove with pliers.

Comment:
Genuinely good bright blue led's and it fits the side panel of my cooler master haf 912 NoNE Actually nice fan for the cost moves a good quantity of fan correct over my gpus

Comment:
Correct Blue colour on fans I got (installed two on side of CM 690 II advance case). Fans are quiet with only minimal air flow noise. Installed with only minor resistance at about threeǚ way in with screw, then secured very easily. (make confident you have screwdrive with excellent head or screws may possibly strip). No vibration, and LEDs are vibrant. Match my front Blue LED fan, which came with case perfectly. none at all Wire length and adapters are each good and overall high quality of fans is superb.

Comment:
It's clear, it's quiet, it moves air. I purchased it to match my other blue LED cooler master fans for my Storm Sniper case. This fan isn't blue -- it's a light teal.

Comment:
quiet, very good value for the cash...as lengthy as you want teal as an alternative of blue leds. teal led colour i'm not hopping on the "it's teal" bandwagon to be argumentative, the lights actually are teal in color.

Moves lots of air and keeps everything cool! Have however to cross over the 40 C degree mark with my I7 930 overclocked at space temps. LED's are bright! If you have this in a space you have to sleep in, you undoubtedly wont have a require for a night light! That aspect drives me nuts. Ordered them since it goes with the rest of my new P.C.'s theme situation. Every thing appears to be blue lights so I believed why fight it.Cooler master Centurion 590 CaseAsus Rampage III Formula X58 MBCorsair 850HX 80 Plus Silver Modular PSUXFX 5850 Video cards in crossfireWD Black 500GB HDD's Dual Processors 32mb 720012Gb's DDR3 Kingston RamPlextor PX-B320SA combo drivePlextor PX-B940SA Blu-Ray burnersthree LG 23" LED LCD Monitors

I love this fanI have one other in spare

Comment:
i had many coolermaster fans before and have always had good experiences, and some of them still working after 5 years of use, this is no different, excellent as always, very quiet, good cooling, looks cool (blue leds), some people may not like the bright blue lights, but i like it, its like a night light for me, and price is very good too, highly recommend this fan to others

Comment:
Nice blue LED fans for a gaming desktop. Runs very quiet. I'd like to include longer screws from Cooler Master and bolts, but still very satisfied. I would buy more if I need it. I recommended it!

Comment:
fantastic value and alot quieter than cool max 140mm fans with excellent air flow. does exactly as advertised. the cool max 140mm fans went into garbage soon after operating cooler master 140s no cons at moment following running for month

Comment:
Huge, quiet and moves a lot of air. Pretty blue lights if you are into that. Huge, measure very first, I'm glad I did. Why is it OK for us to sit about in public with good friends pushing food into one end of our bodies but not out the other?

Comment:
Massive, quiet, moves air. Moves air but doesn't precisely "push" it.It definately is teal compared to my Rosewill blue led. Color is only factor that genuinely throws me off.

Comment:
Awesome with CoolerMaster HAF situations, enjoy it! None yet Use CM fans to turn my HAF X rig BLUE. Got this 140 MM blue LED fan to the back, 3 200 MM fan for the side and two top mounts, and a blue 120 MM for the GPU air duct. Purchased all of these straight from CoolerMaster. Obtaining difficulty discovering a blue 230 MM fan to replace the front red led

Comment:
Whisper quiet! blue LED just right not as well vibrant. Wish it was less costly! Didn't come with any screws. If you are considering this fan get it.
