Pros: Cool lighting

Cons: Noisy at full speed, and cost

I got six of this 120mm Cooler Master case fans from NewEgg.ca...

Costed me $10 CAD per fan factoring in shipping. Total cost $60 CAD.

90CFM and less than 25db??? I got tricked... mad.gif

I don't know exactly how much air is moving through per minute... but one thing for sure is that the noise is very noticeable like having a server next to you. Only two of the five case fans installed are on full speed.

The green lighting is cool, suits my theme. The lights aren't as glowing as they appear in the picture though.

Does the job of circulating air through the chassis, just not quite to the specs... tongue.gif

I don't bother to use a fan controller to minimize the noise... as it defeats the purpose of cooling.

Not going to trash these case fans though.
