Pros: very fast airflow, cheap

Cons: vibration sound when used horizontally

bought 18 of these for my phobya 1080 push pull. pretty strong flow, the packaging rated 90 cfm, and 20 dba,
18 of them still did not cause a loud sound compared to one Scythe Ultra Kaze 120mm.

the tinted grey plastic, or smoked hides dust well, and compared to other fans, i have used, sound the quietest with greatest airflow. when i say quiet, i dont mean dB but subjective noise intrusion, kinda like a low hum vs a high pitched whine sound.

i got them for 10$ singapore dollars each, which is like $7.60 USD. easy to replace if fails as its qiute cheap.

pack also stated a 1-2 year warranty, forgot how many, threw the box away.

i liked the wire, it doesn't have the ugly red, yellow black wires, its all three silver coloured wires. heat shrinked and sleeved would have been nice but they would be thicker. and hey its just 7 USD, how much can u ask for?

think the pressure also quite high listed at 3.04mmHG

thats about all, pretty happy with my fans.

I too like these fan's. They are great for case fans.. Not so good for air coolers though..
