Cooler Master MegaFlow 200 - Sleeve Bearing 200mm Silent Fan for Computer Cases (Black)

Pros: Decent airflow - not as high as I would've liked... They're red They're fans They weren't DOA

Cons: Got 3 of these for my HAF X - kinda irritated that the stock ones weren't red to begin with so that's an additional 60 bucks to shell out... but whatever I can deal with it.

Overall Review: Doesn't make me dinner

Pros: I bought one of these fans for my CM HAF-X to help exhaust air out of the top of the chassis. The fan is expensive, but CM frequently has rebates on them to get the price to about $10. -When the fan works, it is quiet and it moves quite a bit of air. -The LEDs are not overly bright, and they can be cut or pulled from their sockets and covered (I use painters tape) if you do not want the LEDs to be overly bright. -Comes with all connectors and adapters you need and the cable length is long enough to route from top to bottom for most cases.

Cons: After about 6 months of flawless operation, the fan started making an intermitten clicking/rattling noise. It would start and stop every 30 seconds or so and was cyclical and was starting to drive me nuts. I finally decided to RMA through CM on their site for eRMA and printed out the RMA form. I had thrown away the plastic blister packing a long time ago, so I bundled the fan up in bubble wrap from some other product and put it in a heavy yellow legal envelope and mailed it out. Weeks went by and no acknowledgement from CM for arrival, no change in the eRMA status. Finally I called CM to check on the status after about 3 months, and they said they had no record of delivery. I did not bother to get tracking, just sent it out 1st class because it was a $10 fan and shipping already cost me $4, I didn't see the point in spending as much on a replacement as a new one, but still felt the product was faulty and should be replaced under RMA. The first rep did not seem willing to help me, basically blowing me off saying unless he got a confirmation number, he wouldn't be able to process the RMA. I just imagined a huge pile of RMA junk with my fan sitting at the bottom of it at CM's warehouse, so I was kind of frustrated this guy was going to pull that on me. So I looked at my credit card statement and was able to find a payment to USPS a day after I filed the eRMA and called back with that info. The 2nd guy that answered was much more helpful, and did not hesitate to say he would send a replacement out sometime next week. This 2nd rep basically changed my review from 1 egg to 4 and prevented CM from going on my blacklist. I've got a bunch of CM chassis and products and have been very happy with them overall but this would have turned me off of them. Sure just a $10 fan, but it's the principle of standing by your product. I did receive my replacement fan about 2 weeks later and all has been well since, so thanks again to CM service for setting things right.

Overall Review: I do think this fan will fail again at some point, so to that end, save the container. Also, if you send out RMA, I would highly consider getting a tracking number even if it's just delivery confirmation. Lastly, to help reduce the wear and extend the life of your case fans, you should try to shut down your PC or use S3 Sleep so that the fans aren't spinning all the time while the PC is idle and you are at work/sleeping.

Pros: -Silent -Moves air Used this replace a fan of the same model that had started to make a slightly clicking sound. Replacing the fan got rid of the problem, this one is completely silent.

Cons: Replaced a fan of the same model that started to make a slight clicking sound after just 11 months. Only one in 6 of my fans of this model had this issue though. Pretty good odds.

Overall Review: A little disappointed that I had to replace it at all. However, I have 6 of this fan total between all my systems and that one is the only one that has had any issues (and oddly enough was one of the newest). The 2 in my main system are almost 3 years old now and have never made a sound. I think the odds are pretty good that you will get a long-lasting silent fan.

Pros: This fan is a low speed fan that moves a lot of air due to size and as such is very quiet perfect replacement for those cases that have an annoying lighted fan if that bothers you but I do not care if lighted or not just care that it keeps system cool and running and this does just that

Cons: none since I got it on sale

Pros: -Quiet -Clear -Red

Cons: none

Overall Review: Fits perfectly in the extra top mount in HAF X series case from cooler master

Pros: Quiet No LEDs Solid air flow - moves big amounts slowly as opposed to smaller amounts quickly (FYI).

Cons: None.

Overall Review: The whole purpose for buying this fan was to replace a perfectly good fan with this one, simply because it had no LEDs. I am surprised at how nice of a fan it really is.

Pros: Moves a lot of air. Black. Fits a Corsair 550D. Price is great

Cons: Wires are not sleeved.

Overall Review: Much better than 2 120mm fans. Less noise and more air

Pros: This fan was purchased for an unRAID server that houses my media library. I started having issues with the stock case fans not being able to cool the 4 x 3TB HDDs when they were streaming media throughout my house. I installed this in the front of the case directly in line with the HDDs. Within a few minutes, the temperature of the HDDs had dropped by about 22 degrees. Although the fan has a high flow rate according to the manufacturer (110 CFM), it is very quiet.

Cons: None

Overall Review: Bear in mind that the blue LED is bright and will almost light up a room. I wouldn't keep this in a bedroom, as it might keep you up a night. Unless, of course, you want a blue nightlight. :)
