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

Comment:
for a 5 dollar fan you can't go wrong the blue led is slick looking and it does what its suppose to, move air. It's quite quiet I would never be able to hear it over the fan on my video card.Ordered 10 of these for a lanboy air build and very satisfied.

Comment:
this fan is so cheap after pm that no complaint at all as long as it works and hopefully last over 2 yrs.

Comment:
they are very quiet and cool very well

Comment:
I got two for my computer. They appear to run well, but maybe not the most noise-free.

Comment:
Honestly, I will not buy any fan other than a Cooler Master. These things are quiet and fast. They work even better than fans priced twice as much. Plus they look way cool.

Comment:
just what I was looking for.

Comment:
poped it in no problem, working so far, and adds that cool blue led effect to my case.

Comment:
Case had two, bought two more. Does a great job cooling pc and looks cool too. Only problem I had was the intake fan made a whistle from the side panel where it was mounted because of the fan blades being to close to the holes on the sides. Put about a eighth inch difference with foam and no more whistle.

These fans do a great job of cooling my system. I would buy more of these in a heartbeat.

Comment:

Comment:
It does this job well.

Comment:
This fan goes right along with the other fans in my CoolerMaster case.Quiet and puts the airflow needed.

Comment:

Comment:
Nice BLUE lights for my PC case.It cools its very well.

Comment:
Very quiet, very powerful, and my mobo can control it's speed depending on the system temperature. It also looks great with its blue LEDs and it's semi transparent black build.

Comment:
First off this fan looks great, the semi transparent black fan blades combined with LEDs are eye candy, and it runs completely silent while delivering high air flow

Comment:
Fan is very quiet and seems to move air well. The LED adds a nice touch, but is not annoyingly bright or overpowering. Great fast shipping.

Comment:
this fan circulates alot of air keeps my case running at aroung 30 celcius with 2 of them, very bright and makes my case look great

Comment:
Used Silicone fan mounts on this. Very quiet at roughly 1700 RPM. Can hear more air than fan noise from the back (this fan replaced an old unlighted 120mm exhaust fan). Nice brightness and makes the back of the case look sweet!

Comment:
Quality fan moves decent air for the amount of noise witch I think is quite low. LED's look good but I prefer a clear housing that lights up for more light in the case. One thing to note the fan blades are curved and shiny so they reflect any light shining into your case which kind of spoils the look of the LED's.

I bought 2 of these and they came in 5 days and i had them shipped to Japan. So thanks for once again shipping my products in a timely manner. As far as performance, the fans are great. The produce very little sound and a lot of airflow. I would def buy this product again.

Fan works well. Much better than the other piece of junk I had in its place. Puts out a decent amount of air and looks good while doing it. Was worth it to buy two of them to increase cooling in my system without breaking the bank. it's ridiculous that a fan now days cost so stinking much, so it is nice to see that there are still fans out there that are not horribly expensive. No problems with mounting the fans upside down. I've got them pulling air out of the top of my case. Helps to keep things cool.

Comment:
Very nice looking, just a little issue, they're louder than my NZXT M59's stock fans lol.

Comment:
Good quiet fan, love the blue color glow... I plan on using this fan in our travel trailer bathroom.
