Pros: Excellent airflow! Very quiet! Easily mounted and decent cable length. No problems installing and hooking it up in my NZXT Source 530 case.

Cons: Wish I could fit 2 in the front of my case

Other Thoughts: I guess for some it wouldn't fit right or whatever, but in my case it was perfect. I had no issues installing it or routing it to my fan hub in my Source 530 case. I wish all my installs were this smooth. Great airflow and quiet. My case doesn't get above 30c.

Pros: Pushes good airflow, case stays below 30c. Came with right screws.

Cons: The 2 main gripes I have is that they are not quiet at all. One fan I had when mounted as an intake rattled, as if it were hitting something, even though there was nothing obstructing it. Remounted it as an exhaust, and it stopped rattling. So I left it as an exhaust, but still annoying. The rest don't do that, but they still aren't quiet. The second is they have extremely short cables. I have an NZXT Source 530 and trying to route them for cable management and hook them into my fan hub was impossible for 2 of the fans, luckily my mobo had enough sysfan jumpers.

Other Thoughts: They do the job, and I suppose at this price you can't expect too much. But still, they do cool well, just wish they were more quiet and user friendly about it.
