    Pros: I bought these to replace the fans that came with my h70 water cooler. Let me tell you, these are a huge improvement over the h70 fans. Compared to the H70 fans, these really are quiet. My computer sounded like a vacuum cleaner before these fans.
    Cons: I don't think they move quite as much air as the H70 fans but they are close.

    Pros: Work great quiet and powerful
    Cons: the way you mount them is hard. The plastic holes dont have threads in them and the screws it comes with are made to make the threads.. i hate that system because you either have to screw the screws in and take them out and then mount the fans or if you mount the fan with out pre screwing the threads you have to apply alot of pressure and plastic may snap.

    Pros: These fans rock, as long as you don't restrict intake. this is my third R4, although my first one without LEDs. I plan on picking a few more up in the future.
    Cons: As I said before, restrict airflow and you'll her nasty noises from air struggling past whatever is in the way.

    Pros: These things are quiet and they move a pretty good amount of air. I literally held one up to my ear and could just barely hear it at all.

    Pros: They really are as quiet as the claim to be. You will hear them, they aren't silent, but the clearing of a throat is louder than these fans (I am using 7 of them in my case and this comment holds true). They also move a huge amount of air. I <3 these.
    Cons: None thus far.

    Pros: 1.) I am using it as an intake on my Cooler Master Elite 332 case and it sucks alot of air in. Keeps it pretty cool For my needs however, 69CFM is not needed.
    Cons: 1.) Since its just a case fan, adjusting RPMs means getting a fan controller. Not the worse thing ever, but cooling starts adding up, fast.
    Its really loud. Really, its quite loud. I unplugged it from the 3-pin and just let the stock exhaust run and the machine was 75% quieter.
    2.) Sleeve bearing. I bought this at a local store not looking at the bearing type. Sleeve bearings are the loudest and worst quality of all bearings. They deteriorate quickly. Case fans should use either ball bearings, fluid filled bearings, or ceramic bearings.

    (I bought 2 of these for my Cooler Master Scout) Substantially louder than I expected 19dBa to be. Lesson learned! Both of these are on the side of my CM Scout case, and the top one makes a horrendous 'whoosh'ing noise, like its sucking air more than just moving it through. I put my hand a few inches in front of it, and the whooshing noise goes away. I have to learn some things about physics/acoustics to understand this I guess.

    Fans move a lot of air at low rpm. Fit and finish look superb. I purchased 6 fans at the same time. 4 of the 6 fans are noisy as all get out. I purchased the Coolermaster's to go with my new Coolermaster 690 Case. While they push enough air that the exhaust stays cool at max loads the sound and vibration are driving me mad. I am trying some anti vibration connectors once they come next week but there is so much noise and vibration I am not sure it will help.

    Pros: Decently quite and also moves a decent amount of air.
    Cons: For some odd reason, these particular fans refuse to run properly when wired in series and powered off a 24VDC power supply. I've tried it with two of these fans and also one of these fans and one from another brand. The other brand fan runs fine and these "try" to spin but just make some noises. I have also bought several of another brand and have them wired in series and powered off the same power supply. Running beautifully. I can only assume these fans have some circuitry in them that keep them from being run in a series connection setup.

    Cons: None
    Quiet, look nice, and move alot of air. Comes with a adapter but they have a fairly long 3pin cord themselves already. None I have these all connected to a Asus Maximus II. With QFan disabled they run at their max speed, for the 90 CFM (check CMs website for full detailed specs) and they really do move that much air but are louder, probably 24dba which isnt bad considering the amount of air they move. With QFan enabled, they run @ 1200 RPMs and are near silent, I hear my hard drive over them. Unfortunately with them plugged into the motherboard, I couldn't get them to go at their rated speeds or CFM, to get this I had to plug them into the adapter. I think the specs are dead on about the amount of air and noise they produce for 69CFM @ 19dba. These are the best fans I have come across yet, minus not being able to use my motherboard headers, but thats easily solved with the adapter. I have 2 of these, plus 2 of the blue version (LED) cooling my system now, and temps have dropped considerably 5-10C depending on which part of the system.

    Pros: Replaced two old Cooler Master 120mm's that came with my 690 case. Placed them on top with exhaust duties and they move way more air. Blue lights are about perfect if you don't like them too bright.

    Pros: Looks good
    Cons: Was noticeable louder than the 3yr old thermaltake fan(finally gave out) it was meant to replace and it moved less air, according to the specs for the previous fan this one should have been much quieter(10dba quieter) and moved more air(20-30cfm more). After moving fan to another system where noise didn't matter the fan lasted 2 months before the bearing started making a horrible grinding noise.

    Pros: On my Prolimatech Megahalem, it works pretty well. Keeps my Q9550 @ 4050mhz @ 1.2v at an absolute peak of 53c with one fan. ambient temps are around 21c Has decent static pressure (2.94 mm h2o) for HSF fan use, but could be better.
    Cons: I feel like they could make it push a bit more static pressure, as it is designed with HSF use in mind.

I feel like they could make it push a bit more static pressure, as it is designed with HSF use in mind. I cant comment too well on noise, as my main exhaust fan drowns it out for the most part. seems pretty quiet, but its not a personal concern either way. Fan stat of 90 cfm is @ 2000rpm, so keep that in mind. Monitoring your temps is not OCD by any means, you always have to see if the new thermal items make a difference!

    Not that loud when placed well. 70cfm not 90, and defiantly louder than 19dba, but not to loud. The intake side of the fan, has to have clearance of at least 2 inches, even if their is good airflow from the side (bottom fan in a cosmos 1000 for example), if this is not done than the fan gets a lot louder.

    -cheap
    Cons: -OK, for some reason, if this fan isnt moving at 100% speed, it begins to rattle as if it's not stable. It is extremely annoying and drives me nuts. I basically have to set this to 100% in my bios for it to act normal.
    According to HW Monitor, when this isn't running at 100% speed, it would go 1200 RPMs then jump to 6000 RPM, then go back down again, etc etc. Not sure why
    -Holes are not pre drilled so you need to drill it yourself.
    -Extremely Fast and moves good amount of air

    Pros: Good quailty finish, quiet, cheap and moves a lot of air.
    Cons: None so far and hopefully they last a good amount of time.
    Good quailty finish, quiet, cheap and moves a lot of air. None so far and hopefully they last a good amount of time. Hooked 2 of these to my swiftech 2 x 120mm Radiator. They are just a little bit louder than the antec tri cools on low setting but the air they move is just amazing for the noise levels/price. I'm not sure if its 90cfm but it sure feels pretty close and better than the tri cool.
