COOLER MASTER R4-L2R-20CG-GP Green LED Case Fan

Comment:
These fans are supposedly 90 cfm but i have an 80 mm fan that puts out more air than these do even if it sounds like a jet engine... i expected more air flow, but what do you expect for 7 dollars they are quiet and cool looking though and came with the 3 pin installed on fan as well as a 4 pin molex for direct power supply connection so i rate it a 3 due to lack of power

I bought these fan for my case, as some other guy said, same brand, big green and black case, green logo in the front. These are not the brightest fans you will find on the market but the more you put in the brighter it gets, and its bright enough atleast for me. Installation was a little tight with the screws, just have to put some extra aggression to get the screws in, but once they are in tighly they make very low noise and it just pushes air! If you have ever purchased more expensive fans you will notice these will have same or higher quality, dont back down, especially if you have that case! enough with blue and red.

Ive had any brand before you name it. This are the most silent of them all considering that they are running at max OMG and the air they move. More than the thermal take. Thermal take has to turn at 2800RPMs to blow more and that is just stupidly loud. This are the best.

I had doubts about this fans output of 90 CFM but plug it in and you know it is doing what they say it would, nice green LEDs not overly bright or under bright, and they are quite as stated.

I picked up a blue and a green fan for a recent build. Pretty quiet, and they move a lot of air ... and look cool doing it. A great deal!

I decided to make a air purifier with 2 of these fans and it works better than i thought. I recieved a 16 inch hepa filter and added these 2 fans to the ends of it. If you want to see a pic of the air purifier i could email it to you. These fans really push air

These are great fans. Very quiet and bright. Moves alot of air. I would order these fans again.

Over all the fan is a beast. Looks great runs quiet and it's green! The only issue I had with the fans were the lack of my tools. I recommend the right Phillips screwdriver. I had a short handle one which proved no driving power for the screws took me awhile and almost striped the head of the screw. Also with the lack of the right tool I wasn't sure which way the fan blew in or out. As far as i saw there were no markings showing which was the outflow. Other then that it's a great fan no issues with the fan it's self. Would recommend :)

Really quiet and moves quite a lot of air. Better price than newegg. I will buy more.

The only complaint I have is the screws are extremely hard to get in, besides that they are working fine

Comment:
Very bright and moves a lot of air

I got four of those to go with my new case for a total of 6 installed - can't say what case because names are not allowed in here but you know which one, same brand, green, graphic card company logo on it, anyway, fans are quite, move a ton of air, cools down my system to 19 degrees at idle, all four controlled and when on max i can play air hockey on the two top ones. awesome fans!

Had to modify my chipset fan tunnel a bit, but this thing moves alot of air and looks cool while doing it, you can definitely hear it running,lowered my temps by 15 degrees, great fan for the price.

Comment:
I have about 5 of these. They move a lot of air and look good. I did have one break on start-up at the plastic sleeve.

Comment:
I bought these to go into my CoolMaster Nvidia case. The fans work great, and my computer is very green! I have two of these on the top of the case, and you could use my case top as an air hockey board, that's how powerful they are.

Comment:
All I can say is they work great not real loud. Good deal!

Comment:
Would recommend, love the color too. Easy to install.

Runs quiet and moves a lot of air. Screws were incredibly tight, ended up drilling screw holes out to be able to get the them in all the way in.
