COOLER MASTER R4-L4S-10AB-GP 140mm Blue LED Case cooler

Pros: the fans are very bright at first, and they are cheap

I cant believe the high rating this product has.

Cons: these are not 16db fans, and they don't move 60cfm. i was looking for case fans that looked cool to put in my Lian-LI pc-a71f.. these had great specifications and a attractive price so i bought 2 of them. after about two months the brightness of the led's faded away so i bought replacement fans, i went with the green LED Apevia fans, those fans are rated at 20db and 59cfm.. i was surprised to find that they apevia fans were much quieter than the coolermaster fans, and they moved more air. the apevia fans lasted me about 6 months before one of them got loud, i replaced those fans with Corsair fans and couldn't be happier. i don't have led fans anymore, but at least my computer is silent and moves alot of air.

Other Thoughts: being a audiophile and obsessed about changing my room acoustics I bought a cheap loudness reader from office depot so i could actually see how loud these are. being held in the air, the cooler master fans are actually 22DB, then when put inside a computer case they get louder due to vibration and turbulence, i got a reading of 28DB when in my computer case... at no point are these fans 16db! the Apevia fans are actually 20db when in the air and 23 when in the case. spend a little extra money and buy something good.

Pros: Cools well
Looks great with the blue LEDs

Cons: I had to power drill the provided screws into my CM HAF case but not enough trouble to dock an egg.

Other Thoughts: Does what it should!

Pros: -LED dims down with my fan controls on case.
-Quiet.
-LED fits in nicely.
-Cheap.

Cons: -Doesn't move a ton of air, is mostly for the aesthetics.
-Fan blades pretty thin, again, doesnt move a ton of air.

Other Thoughts: You get what you pay for.

Pros: These 140mm Blue LED fans perform about as you'd expect. I have a mid atx case that has plenty of cooling options and I bought a couple of these to fill up some space that some 120mm's weren't quite filling. One of the fans I bought has a slight rattle to it but I think I can live with it.

Cons: THE HARDWARE INCLUDED WITH THIS IS TOTAL GARBAGE!!!! Please, if you are buying these I STRONGLY recommend using any other screws other than the ones included with this fan. My normal everyday phillips head screw driver (the same one that I used to for the entire custom build) stripped these screws like a hot knife going through butter. I noticed it right after only putting in two but I will more than like have to drill them all the way out and permanently damage the fan's plastic case if I ever need to remove these. HIGHLY disappointed. For the other fan I just went to my local hardware store and bought screws there that were the same length.

Pros: Fan is quiet, decent airflow, and the clear plastic looks really nice with the blue leds.

Cons: None really. I wish they made this fan in High Air flow(more blades) instead of just high pressure.

Other Thoughts: I messed up and bought the 140mm when my case only supports 120mm(I know...stupid), but I made it work using the mesh holes around the screw-ports. I had to put some force into it and the fan frame is slightly contorted because of having to force screws in. I was affraid it would make the fan rattle or crack the frame...but still after a month, VERY quiet with no noticable difference; a testament to durability.

Pros: The led's are not to bright and not too dim, perfect for me

Cons: no conss

Pros: -Blue LED
-Decent Airflow

Cons: -Weak Blue LEDs

Other Thoughts: Installed in the front of a Cooler Master Elite 430.

Pros: Simple installation into my Rosewill Challenger case top fan slot. Works great and also looks great with the blue light.

Cons: Nothing i can think of.

Pros: -Silent & effective
-Clear Blue Led
-Nice Package!
-Happy!

Also 4 to 4 pins adapter inclued

Cons: None yet

Pros: -Bright led's
-Moves a TON of air
-Works great with a fan controller

Cons: -Screw holes are hard to get to
-Small strobe effect disrupts led glare
-The price point is slightly to high. I would prefer in the 8-12 dollar range. Seventeen bucks is a bit much for one fan.

Other Thoughts: This is an excellent 140mm blue led fan. The lights are bright, and the build is durable. When at low fan speeds, this fan still moves a ton of air. when cranked up to 80% or 100%, it is a monster for air cooling. Aim it right at your cpu!
