COOLER MASTER R4-L2S-122B-GP 120mm 4 Blue LED Case Fan 2 in 1 pack

Pros: blows and glows

Cons: none

Other Thoughts: works perfectly

Pros: Quiet! Definitely quiet. I installed 4 out 5 fans in my TK V4 case (it came with one already) and I am LOVING it! They are BLUE! And of course they have somewhat of a blacklight effect in my case. I did a little fluorescent yellow accent painting to take advantage of it. They are quite Bright LEDs so if you do not want it to shine, these are not for you. I have had them almost a year and no problems. You can not beat the price for these. I bought two packs for around $10 each pack. That is $5 per fan. You just can't beat it. And if you could, would you want to?

Cons: They are not massive air movers. They do have noticeable air flow. I have two pushing and two pulling (not counting my TK fan) and I have not had a heating issue yet. I am overclocking a Core 2 Duo with a stock heat sink and I am currently running a passive heatsink on my video card. Neither one has come close to overheating while gaming. This being said it is not a MAJOR con. But I know some will gripe about it. One con is they should be available in other colors. Green, Red and Purple.

Other Thoughts: Personally for the price they can not be beat in my opinion. They move enough air for me and they look great. They are cheap for a new build ( they saved my bacon on cost ) and they seem to last. Love Them! Thank You Cooler Master!

Pros: These are fans are very quiet and perform well. They will definitely drop temps if you will use them as intakes and perform as good exhausts as well. They worked right of the bat, I have hardly had defects with CM.

Cons: none

Other Thoughts: Nice looking blue led's. It cam with screws and fan shields. GREAT DEAL.

Pros: The fans produce a nice somewhat bright blue shine! Both fans that came in worked. (I actually ordered two of these and all four work) Quiet! I was testing them all out inside my case with side panel off and you couldn't hear a thing!

Cons: The holes for the screws are very hard to get aligned properly. I absolutely destroyed the screws trying to get them tightened. I ended up using a flat head instead of the Phillips.

Other Thoughts: Definitely will get these again!

Pros: Moves air pretty well and they aren't loud, much quieter than OEM fans. Cheap.

Cons: Don't move as much air as more expensive models but these were a good price and do well.

Pros: Nice and quiet even at full speed! A year later and all 4 leds still work! :)

Cons: Can't think of any!

Other Thoughts: By far the quietest fan in my case. Will keep these in mind for future purchases.

Pros: Looks cool. 3 pin connectors ok for motherboard connections. Somewhat quiet.

Cons: When I put my hands in front of the fans I don't feel much air movement, so I don't know how well these are working to move hot air out of the case. They are mounted at the top of the case. Another con is that they don't include 4 pin molex adapter cables for use with power supply connectors when you run out of motherboard connections.

Other Thoughts: 4 pin connectors would be nice for newer motherboards. Not really an issue. Too bad these don't come with molex adapter cables so that I could use them with standard power supply connectors.

Pros: -low noise
-cheap

Cons: -low airflow and low pressure
-not even enough power to move a notecard from 1 inch above it (blowing up)
-takes a lot of voltage to start, needs to be on full most of the time

Other Thoughts: Just ditched these in favor of some better fans

Pros: These fans are very quiet when running at max speed. The leds are an awesome feature too. Easy to install and it comes with screws which fits perfectly.

Cons: None so far

Pros: Beautiful and so quiet! very good product.

Cons: NONE
