Overall great product

Andrew S., Newegg

  • Pros: Lots and lots of air flow being pushed with these fans.
  • Cons: Kind of loud fans. Once you install it, you can't really move it. For instance, you can't go from horizontal to vertical as my ball bearings now get loud if i switch it. Do not use this item as an intake fan if you have mesh over your fan. Gets very loud

2 Year update

Ivan P., Newegg

  • Summary: This fan works fine as long as you DO NOT mount it horizontally. The people complaining about the fan making noise is more than likely attributed to improper mounting orientation.
  • Pros: 3 pin is a big plus moves a ton of air static pressure optimized
  • Cons: SLEEVE bearing very loud at full speed (1900-2090 rpm)

Moves a lot of air, noisier than the specs

George H., Newegg
17 September 2015
  • Summary: It's a case fan. With cool red LEDs. Looks good, works well, just a bit louder than expected.
  • Pros: Moves a ton of air. LEDs look neat. Otherwise, it's a no-fuss case fan.
  • Cons: It's not as quiet as the specs would lead you to believe, though not hugely loud. Um.... won't save world hunger?

  • Pros: Abit quieter. Nice LED.
  • Cons: Not as quiet as I'd hoped but not that loud either. Didn't really help as much as I'd hope but still a quality product.

Great fan for push setup

Sharon S., Newegg
17 July 2015
  • Summary: If your using them to push air though a rad, heatsink, or out of a case, there great. If you want them as intakes pulling, they become turbines!
  • Pros: This fan is really powerful and quite when running as a push setup. The LEDs create a nice effect, but don't create an eye sore.
  • Cons: In a pull config... The things are turbines! I guess it's the fan blade design, but their soo loud!

Solid

Syed M., Newegg

  • Summary: If you plug this in through molex, it is LOUD. In my book it's always performance over anything else, but when I unplugged my one fan from molex it was a breath of fresh air (I bought 2, one is plugged into the board). Just a warning, it is unbearably loud using molex. Otherwise, good fans.
  • Pros: They work, red LED lights, quiet, come with molex adapters, 3-pin
  • Cons: Cords are very short Red LEDs aren't as bright as I had hoped Screws are hard to put in the first time (to be expected on new fan install)

  • Summary: this fan is silent as long as there isn't a filter or some sort of grille put right in front of the air path, if there is all you will hear is air being sucked in.
  • Pros: Moves a TON of air Nearly silent.. see other thoughts Red LED's
  • Cons: LED's are a little dim

Cooler Master Red LED Silent

Jeff N., Newegg
1 May 2015
  • Summary: Looks great, and definitely a good value despite the one malfunctioning unit. I would still recommend this fan to anyone looking to increase the air flow in their tower.
  • Pros: Nice fan, good airflow. Look great in the case.
  • Cons: Bought 6 of these for my full size tower. One of the fans sounds makes an annoying grinding sound. So I either have to send it back and pay almost what I paid for it to RMA or just deal with the annoyance.

Sickleflow 120mm

Eric G., Newegg
23 April 2015
  • Summary: In all, its a decent fan for the price, you really get what you pay for and maybe a little more. Solid choice for those who dont feel like paying the premium of $20+ a pop for a single fan.
  • Pros: ~Respectable CFM for the money ~Feels like lots of static pressure, great for coolers/rads ~LEDs arent blindingly bright, just the right amount of light
  • Cons: ~Somewhat noisy, especially when the fan is obstructed in any way ~Feels cheap, lots of creaking and some sweating when screwing them in for the first time
