4 out of 5 eggsgood but loud

This review is from: Cooler Master SickleFlow 120 - Sleeve Bearing 120mm Blue LED Silent Fan for Computer Cases, CPU Coolers, and Radiators

Pros: Fan is working just as promised.

Cons: I thought the complaints about the noise were by those that wanted no sound at all but I was surprised at how loud this fan is. Unless you run it at a lower speed it has a very high hum to it and I probably will purchase another fan and keep this around just in case I need a quick replacement.

2 out of 5 eggsAnnoying fans

This review is from: Cooler Master SickleFlow 120 - Sleeve Bearing 120mm Blue LED Silent Fan for Computer Cases, CPU Coolers, and Radiators

Pros: First off, I owned 8 of these fans back when I had a Corsair 800D, when noise didn't really matter because it was a workstation machine. Now, however, having the machine 2 feet away, noise tends to bother me. I thought I had learned my lesson when 7 of the 8 died within two years from non continuous use, so I picked up 3 more this time around. On the plus side, they look great when lit up, and move quite a bit of air when turned up. However....

Cons: The noise is astoundingly loud and abrasive. I am very glad to have a fan controller. Anything above 33% creates a consistent whirring and humming that I can't stand at all. Tried both veritcal and horizontal, vertical was worse. I thankfully don't necessarily need these fans above 33%, so they are ok, although there is another sound they are producing that makes me want to rip them out and wonder why I even pulled my Apevia fans out in the first place.

Other Thoughts: If noise isn't an issue, load up on these. If you're trying to maintain your sanity, avoid at all costs. I have to keep a box fan running in the background so the little bit of noise they DO create at 33% doesn't drive me to the point of tearing them out.

5 out of 5 eggsGreat Fan

This review is from: Cooler Master SickleFlow 120 - Sleeve Bearing 120mm Blue LED Silent Fan for Computer Cases, CPU Coolers, and Radiators

Pros: The fan is very quiet and moves a lot or air. I like the blue color it emits.

Cons: None

Other Thoughts: I've found out noise can be created if the surface where the air passes through is ribbed or has fins, such as the side of a computer case. I experienced this and tried two fans from two different manufacturers blowing different and variable amounts of air and the result is the same. The fans appeared to be balanced and did not exhibit vibration which could cause noise. So when people report problems with noisy fans the real problem may be the design of the case where the fan is mounted that is actually causing the noise and not the fan itself.

5 out of 5 eggsExcellent Fan!

This review is from: Cooler Master SickleFlow 120 - Sleeve Bearing 120mm Blue LED Silent Fan for Computer Cases, CPU Coolers, and Radiators

Pros: Quiet and moves a decent amount of air.

It uses self-tapping screws, which can be a chore at the start, but once it goes all the way through, it's a piece of cake to tighten.

Cons: None so far.

Other Thoughts: Love the first one so much, I bought 2 more to replace my stock fans that came with my Antec 300 Illusion case.
