Nice fan at a nice price. But, don't mind to add light into your case with this one...

Experience: 5 Days
 Verified Owner
cant see much of the red light comapred to my other fans
by far the loudest fan in my PC (out of 5 fans)

Experience: 7 Days
 Verified Owner
Keeping it cool.
One of the screws stripped easy, but that's kind of on me.
Its a fan.

Experience: 7 Days
 Verified Owner
Quiet, Red LED, low cost, easy to install. Great value for what you get.
Didn't have free shipping, shipping costed me more than the fan(s) I purchased. Wasn't two-speed adjustable like my old fan.
Definitely worth picking up if you need a red-led replacement case fan.

Experience: 1 Weeks
 Verified Owner
Great air flow
LED looks good
A little loud
Put four of these in my case and they are a little loud. One of them seems to make a bit of a weird noise at low rpm too. Otherwise, they look great and move tons of air inside the case.

Experience: 1 Months
 Verified Owner
Red Lighting
Pushes air well
Cheap, buy on sale always
Doesn't state which way air flows through on website, or arrows on fan, although that's easy to figure out in person
Red lighting is nice with black outer rim. Clear plastic shines too much and makes it look cheap even though this is good for the price

Experience: 1 Weeks
 Verified Owner
Looks kinda cool
Screws were a pain to put in my n200 for some reason so after 15 minutes I gave up

- Surprisingly good airflow power
- very inexpensive
- Not as bright as the green one
Got 3 of these ones running in my system. Airflow-wise its great considering they're not very expensive. The only issue is the red one isn't as bright as the green one.

Experience: 1 Days
 Verified Owner
These fans can push a lot of air! bright leds
These fans are great and they are cheap too. i love how bright the led lights are and the fan has a solid build quality

Experience: 1 Months

Pushes air FAST, high quality, excellent durability, cheap price (compared to some other 120MM fans at least)
None at all.
I purchased one of these almost a month ago, and it works amazing. For this price you can't go wrong with it. Plus it's very durable, and pushes air very fast. It arrived very fast, 4 days is great. Affordable and fast shipping - exactly what I'd except from NCIX :D

Overall, 10/10. Plus the red LEDs on it looks pretty sweet.
