-Cant complain. PM'd for $4.95. Bought 3 of these for my Antec 300. Its a bit loud, but it looks good and it pushes a lot of air.

I had a cpu fan failure. Replaced the heatsink and all case fans at that time. I bought 3 of these. Installed two for case fans and one for the heatsink at a HDT 1283s. I had some older style cooler master fans before rated at 1200 rpm. The R4 are only a little bit louder, but NOT "Loud" at all. I highly recommend them. The improved air flow is amazing compared to what I had. The cpu fan runs at 1500 idle and full speed under full load. I can't hear the difference. The LEDs look nice too with the extra blades, they have more reflection or whatever. For $10 bucks, you can't go wrong!My mother board and gpu are running about 5C cooler!

Decent fans for the money. The Leds are a nice color and quite bright. They are pretty average in terms of noise. If you are going for a green color scheme these are pretty good fans.

$5 fans. Win.LED. Win. (if you like that)Good CFM? Win.Overall this is a winner. Fits in my case and lights it up good.

Used for a push pull configuration on a hyper 212+. Seems to have sufficient static pressure to be used in such a set-up. More products should have green LEDs , so tired of the blue glow.

Comment:
I'm using these for push-pull on an H50. They pull lots of air and everything is running very quiet, but they're pretty loud.

Comment:
well it does the job perfectly. a got four of this in my sniper case and its really quite. the color green is a plus...

I personnally dont care about the CFM. It is fine as long as I am not sleeping in my room while the computer is turn on. I have 7 fans, they all make a lot of noise.

Comment:
i bought 3 for my antec 300 build. they loook great and push lot of air if i compare to my antec 140mm fans. i recommend those fans to everyone. ( they look better for intake ) i read a lot of comments that they arrived brroked. i took a chance and i got them on perfect shape. 4.98$ with pricematch. ncix is the best with PM.

I bought these to add another case fan to my Coolermaster Elite 310. I used the supplied screws and they worked flawlessly. Pretty quiet. Would buy again.

Comment:
These fans are quite nice. I got these for a friend for his green machine, although the only complaint is they are 2000 RPM which is not necessary for a case fan really. If you do not have many 3-pin connectors, I suggest a good fan controller. Otherwise fantastic fans.

Comment:
Brought 3 for my Antec300 build. One of the fans came with an led that flickers occasionally. The other two fans were just fine.

Comment:
Bought 2 set. 3 green and 3 blue for my 2 antec 300 build. It works great. Noise level - a little louder than the stock fan which came with the case on low settings.

Comment:
this fan is pretty decent for its price, you can get this for about 5dollars after pricematch.the fan whines a bit at max rpm, but when tuned down with fan controller its fine.

Comment:
Purchased this fan because it has a green LED and to replace my loudPSU fan. While it isn't as bright as I had hoped, it is fairly quiet and has good performance for its price.

Bought two green version, they work as a fan should. Although this fan vibrates like a 2000RPM fan, the CFM maybe over rated, or this fan has a weak air pressure. When I compare it with a Yate Loon fan(D12SL-12), side by side, that is rated 47 CFM, the difference was extremely minimum. Noise level is labled 19db, although I have no device to measure, I believe its noise level is above 34db, as 19db is nearly inaudible; or is it 19db above background noise? One last thing, the motor runs hot when the fan is on. I don't know about PC fans, but among all my home cooling fans, the ones with hot motor always have a shorter life span.One of the two fans, started to show signs of failure after 3 weeks of use, compare to the other one I have. Sign: unstable spining speed, stutttering noise from time to time.The reason of rating this product one star is mainly due to unexpected weak air flow, unexpected noise, and suprising hot motor.

I bought both Blue and Green version. Moves a lot of air. LED is decent. The best thing about this fan is that it is quiet. I had Scythe 3000RPM fans that were soo loud even with a fan controller. This however on maximum speed, is very quiet. I have 6 fans in total, and you cant barely hear any noise.

Comment:
I bought both the green and blue version, and the green version of this fan actually has a higher CFM rating than 90 as opposed to 69. However, seeing as they are the same I think this is a typo (the sticker also says 69). Also, the price can be matched to be much lower. They work as well as any other 120mm fan, just be sure to compare their CFM and RPM and anything else that matters to you.

oolmasters' "flag" case cooler the Excaliber would be probably be a better buy for you enthusiast out there

Comment:
It could be price matched to really cheap. It come with a 3 pin to molex connector, and 4 screws. The packaging wasn't as solid as the blue R4 as this come with a plastic bag instead of strong plastic case.I used these fans as a heatsink fans and case fans. There isn't any whine when undervolt.

Comment:
Very good fan for the price. runs quite. Good air flow.Easy to install. can be used on CPU coolers. all around good fan. Maybe not really 90cfm...High CFMLow noiseLimited availability of other green LED fans

Comment:
This is a nice looking fan which moves a fair amount of air; however, it isn't as quiet as advertised. Its a good purchase, but it would be nice if all fan manufacturers could rate their fans based on the same tests.

Comment:
Good fan for the price once you PM it down 2-3 dollars. the CFM to price ratio becomes one of the better out there. Green led is ok and the power cord is a bit short. Good if your fan are close to a mobo power header, bad if you need to route the cable through the case. They do proide a molex extension, if not, but a 4 pin extension, hthey are cheap and will make it work. Finally, DBA RATING IS A LIE ! But since I knw this already, I am hhappy woth the purchase.

Used in an Antec 1200 setup, it makes a great contrast between the integrated blue fans. However compared to the ones integrated into the 1200, they have 4 blue LEDs, while these green ones only have 1 and it is supposed to reflect off the clear blades of the fan. They are not as bright and does not show what I expected. Besides that the speed of the fans is perfect and blows the air around perfectly.
