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

Comment:
I was looking for some extra cooling and decided to try this fan. Its solved my cooling requirements. It is very quiet, Like you have to see run to know it is running.

Comment:
Pros: -Black frame blends with my case better than the standard clear. -Moves a good amount of air -Fairly quiet at normal speeds Cons: -Only has a 3 pin connector for power so the led's dim with the amount of power the board supplies. A little annoying.

Purchased this to keep air flowing through my new case. The blue light is cool shining through the case. Very quiet for such a large fan. Good deal and it works.

Comment:
I purchased one to replace a bad fan. Now I have 5 in my case and a spare on the shelf.

Comment:
the fans have good air flow i have four in my case the only down side i have to them is the led really isnt that bright....

Comment:
I really like how much air the things push. I have 7 of them in my Coolermaster CM690 and it only pushes room temp air out. Very nice but Now my case has a rather loud whistle to it. Definitely worth the cooling though.

The Fan works and looks great!

I have just recently built a high end box and have install an additional 3 fans of this model. For the price the quality was excellent. They flow more air and are quieter then most any fans out there at there price. I agree the color could be a little brighter but the goal is for lots of cool air and as quiet as possible the color is just the bonus. I have 11 total fans in my case and these are as quiet as my larger slower fans in my CM HAF 932. I don't think you would be disappointed with them I WAS NOT!!

I replaced a stock case fan on my NZXT Apollo case with this and added one in front of hard drive caddy. Moves way more air than the stock 120mm fan. Will buy again if needed.

To the user who stated the fan made a loud whine, it wasn't the fan, its the mesh of the case that makes that noise. I had the same problem on my CM 690, and once i cut the case mesh the noise was gone. These fans can't be beat for the money!

for 7.99 how can anybody complain.

Comment:
For this price its unbeatable. It looks great in my Cooler Master Haf Case (replaced all the fans with blue fans because I don't like red lol)

Comment:
Wise choice 2 don't seem to bother me an of noise moves some wind too! Lights are cool! Wise Choice!

Comment:
The lights are cool and the design is smooth on this fan, however, it didn't seem to be putting out as much of CFM air flow as I thought it would but for 7.99 who can complain? It works good enough for the price you're paying, trust me...

Comment:
Quite as can be, Simple led design, cant go wrong with the price!

Comment:
Installing was a breeze, like any other fan. Using as a rear exhaust fan and pushes alot of air. The only noise I can hear is the high air flow it's pushing out. All in all, for the price and performance you can't beat it.

Comment:
Very good fan and quiet at a great price. Just what I expected from this retailer.

Comment:
This fans are great I got 4 on my haf932, they are loud when on full speed but push LOTS of air, for everybody complaining about how loud this is BUY A FRIKING FAN CONTROLLER, I put mine on the lowest speed and they are quiet, and still manage to push alot of air

Comment:
I purchased this fan and installed it in a Cooler master case. It was so loud I have to disconnect it. It made a very high pitched noise, that was louder than all the other 4 fans, CPU fan, 2 BFX 285 graphic cards and a 1000 watt power supply. Don't waste your money on this one!

Comment:
