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

Comment:
Fairly, good lights on it coupled with clear construction, it really glows bright if that is what you are hunting for. Incredibly quiet, I have it installed on a controller in my Antec 300 Illusion as a replacement for the factory best mount 140, to get speed manage and rpm feedback. I know that the controller inherently sacrifices the major 5ㅂ% of RPMs accessible, but even if is only running at 90% it just doesn't seem to move a entire lot of air, even on a positive pressure situation. Slow starter, don't attempt to start out at 10 or 20% power, give it some juice then dial it down. Got it to full the blue effect and to finalize speed controlled situation along with some 120mm units by CM as effectively. The 120's push a bit additional air, but no regrets, case idles at about 29.7C, which is close to ambient, so no important complaints.

Cheaper than any other places that i looked

Moves air. Does what it is suppose to! Quiet. Lights are some-what vibrant, but not really a + or -. None. Replaced two CM 120mm fans on best of my CM 690 situation. Significantly superior air flow at same speed. All my fans are running at lowered speeds through a fan controller or speedfan, so have silent operation! Have these @ 700 RPM, and do quite nicely. When performing videos, will take them up to 800 RPM and nevertheless silent, and fantastic air flow. @ 1000 RPM can hear them (or the air flow), just.

Reasonably priced, quiet and efficient. Precise exact same fan that came stock with my Cooler Master 690 II Plus. Installed two of them and it didn't appear to improve the noise level of my program at all, remarkable. Screws that came with the fan had been tough to get in, but rest assured the screws won't loosen up more than time. That is possibly the point. They look awesome and decreased the temperature of my complete technique by a few degrees. Each and every tiny bit counts!

Bought to use with my Coolermaster Storm Scout case as I switched all the fans to blue led, does what I require, it is also very quite I can barely hear it.

Brilliant lookingEffective at doing what fans doEffortless install (I have a Cooler Master case...)So far so good Sitting subsequent to my laptop or computer is now like sitting in a fridge. The best for the dollars.

Quiet claim is no lie. Super fairly the way the light bends in towards the center from the LEDs. That image does it no justice. It is quite quiet. It appears to blow a lot of air (see Other Thoughts). Certainly a lot more than the two 80mm Raidmax fans the case came with. Case temps are also a handful of degrees lower with this fan. The thing is so quiet, I may cut a hole in the floor of my situation and add a different one. If I do, I'm getting the 1 with out the lights although. Wow, a single lit fan is adequate. Frame was quite flexy whilst tightening the screws. It's good and sturdy now that it's in, but be cautious. This is not sufficient to quit me from buying a different 1 the next time I need a fan this size, nor is it adequate to take away any eggs. I'd rather have it be flexy than brittle anyway. Also I wish there were a way to dim the LEDs without having rising the expense of the fan. They are WAY brighter than the image would have you think. It appears to blow lots of air, but I don't think it produces considerably pressure. The additional away I hold my hand, the a lot more I can really feel the air moving (and it feels like a lot of air), but it never ever seriously feels like it's "pushing" on my hand. I know utilizing my hand to measure air flow is like working with measuring cups to judge temperature, but it's all I got. Also I have two Hard drives in front of it slowing factors down a bit. General, I'd be willing to bet that it moves as much air as the manufacturer claims. The LEDs are SUPER Vivid. I'm not significantly into glowing PCs, and this one is bright adequate to read by. I only ordered the lit a single, simply because the case I inherited had the power and hdd lights built into the front door, and I jettisoned that so I could push the power button. BTW the Raidmax Scorpio is not a very good case unless you're prepared to heavily modify it. Fairly fantastic if you get it for cost-free and personal a Dremel tool even though. Sorry guys, sometimes I ramble.

Good Airflow and near silent operation. None that I can see perhaps a red color selection. I now have two of these in my side panel of 690 II Advanced, my 9800 Gt Dropped about four Degrees at idle

This fan in my opinion is the very best out of the 3 fans I bought. The other two were the Masscool and Aero Cool 140mm fans. The light is a lighter blue than the Mass Cool, and brighter than the Aero Cool. It pushes a decent quantity of air. The Cooler Master can be used as each an intake and for expelling air perfectly fine, unlike the Masscool, which rubs the side of my case noisily if used as an intake. It's doesn't push as significantly air as the Masscool fan, but it's not truly that substantially of a distinction. This fan appears wonderful. It's nice and bright and pushes decent air. It can be used as an intake and for pushing air out equally properly.

Worked suitable out of the box! absolutely nothing

Moves a good amount of air. Reports RPM to the motherboard or digital fan controllers that assistance DC fans. Would be nicer if it moved a bit more air, but for what it is and its low price I am happy with this case fan.

I didnt buy it from here and I just want to comment on it. I purchased 2 of this to replace the best fan that came with my Lian Li/Lancool K62. It has started to make some rattle noise. So I replace it with this. It works fine. It humms along and quiet. No rattle. Its only the 2nd day. I notice the LED is not as bright and its teal. Its close to blue. Wish it expense much less. I read that sleeve is not very good for leading fan. It is excellent for verticle. Ball bearing is superior for leading fan, but far more noiser. Thats what I read somewhere.

Quiet! Wonderful quaity! Well built! LEDs just the suitable brightness none except it did not install itself

Move plenty of air, silent and fantastic seeking. None. Many people have said the LED's on these fans are tealish, mine are not. I have some Antec 120mm blue fans and the Cooler Masters match them perfectly.Also, the Antec 120's I have, have an pretty much frosted transparent plastic, these Cooler Masters have a extremely smooth, glossy plastic. Good seeking!If you're seeking to upgrade the not so wonderful Corsair fans in the Obsidian 800D and like blue; these are the way to go, a lot greater air flow.

Comment:
This fan is nearly inaudible. I can put my ear right next to it, and I would not be able to hear it. Great price too when pm'd. the only problem is that it feels like it's pushing 40-50 CFM rather than the rated 60. The wires are also very short as I was barely able to extend them beyond the motherboard tray.

Comment:
Quiet, functions properly, looks fantastic. No difficulties, can't complain! I got a couple of of these for my Rosewill Wind Knight case which has a blue-lit energy button and front fan. The color seems to match fine and I can not fully grasp how other people are saying the lights are "teal".The lights on the fans I got are definitely and inarguably BLUE, and they nicely match the lights already in the case. They work quietly and do a fine job of delivering cool air to the inside of my case without getting noisy.

Comment:
Big fan - moves a lot of air without having making a lot noise. Nicely compliments my 120mm exhaust and PSU exhaust. Blue LEDs are a good touch. Also a tough fan - read Other thoughts for particulars. N/A. Accidentally dropped this fan about two feet when installing it. Fan was not damaged - phew!

Comment:
Easy to install fans, have directional arrows on them which is a nice touch, and inside my fractal r3 case they look very nice. These fans are also very quiet.

Comment:
Bought this for an intake fan on my coolermaster Elite 370.Does what is supposed too. No complain at all. I would buy again if needed.

Comment:
These are overall great fans for their price. Work quite well as as long as you don't mind low LED reliability. The actual fan seems fairly reliable.

Comment:
Needed a replacement for a stock fan on my LIAN LI Lancool PC-K62. Not a lot of choices when it comes to 140mm fans with a blue LED. This one actually fits perfectly, same glow, good size and soundwise, it is quite silent (can't hear that one over the others). Will definitely buy again if I need to replace another fan in my case.

Comment:
It moved far more air than the stock fans that came in my LanCool K-62 and it seemed to do so extremely quietly. I agree with the other poster that it is a lot more of a teal color than a blue. Also, the light did not appear to permeate the housing quite nicely, it was extremely localized to where the LEDs were at. In addition, 1 of the LEDs was not working on my fan. If you dont mind the teal color, this is a decent fan. It moves air and is quiet. The color and the non working LED just didnt work out for me, so it gets three eggs

Comment:
Really quiet, moves a excellent amount of air, and assists light my tower. None that I can think of. I'm making use of two of these as best exhausts for my Cooler Master CM690 II.

Comment:
Quite quiet with full energy from PSUBright none to report Purchased 2 for best exhaust fans for my case. Screw tightening was tougher than I thoght it should be, but not a big deal. Only if you pointed it out, there is a "slight" teal color, compared with the other blue LED's in my case, but it all blends in effectively and I am really happy with the results.

The blue led's are the exact same shade of blue as the nzxt phantoms power, hdd, and fan control led's.Noise is noticeable and just as loud as the nzxt phantom's stock fans.Works great for blowing additional air onto my hard drives.You cannot use the screws that came with the fan for installation on the phantom, and the screws the case provides are very short, but still allows for the fan to hold well.
