Pros: great, quiet, moves a lot more air then my old fan my coolermaster case came with im thinkin of putting 1 on my bigtyphoon

Cons: ....ummmm not buy 1 get 1 free?

Pros: Pros: - Excellent cooling with low decibels. - very little amp draw - super quiet dual ball bearing motor.

Cons: Cons: - 2 of the 9 ordered were DOA. - A 3rd fan exploded throwing fan blades allover my case.(no wires or anything touched it) - Front intake on CM Stacker 830 was slightly touched by my finger...a simple graze and caused another fan blade to break completely off. - Price

Overall Review: I think i'll be going back to ALL Panaflo fans. I've never had one self destruct or break a fan blade by barely touching it... or had TWO dead on arrivals.

Pros: They push an amazing ammount of air quietly , high quality.

Cons: none

Overall Review: I got 2 of this for my thermalright Ultra-120-eXtreme Push pull configuration for daily use for my Quad Q6600 and it does a great job.

Pros: Both the airflow and noise specs seem very conservative. Build quality looks a cut above...

Cons: None to speak of...

Overall Review: Great airflow and very quiet at full speed. Definitely seems worth the few extra bucks it costs...

Pros: Moves a lot of air, quietly! Much quieter than the fans that came with my 900 case.

Cons: None that I've seen (or heard) so far.

Overall Review: Bought the first one to go with my Ultra 120 Extreme, and bought another to put in the side fan slot in my case. What else can I say, they made a repeat customer out of me!

Pros: Moves a lot of air Quiet Comes with molex connector as well as motherboard header cable to monitor fan RPMs.

Cons: None at all.

Overall Review: Very happy with this fan

Pros: It moves a good amount of air and it's very quiet. I bought one to use as a heatsink fan and I like it so much that I'm going to replace the three stock fans that came with the P180. It is quieter than those fans at its highest setting and I subjectively think it moves more air.

Cons: None.

Overall Review: The reported ratings of this fan are very good compared to similar others.

Pros: Air noise at max output is quieter than the lowest setting for the stock fans on my P180B (Antec Tricool). Moves air and does it well. What else is there to say?

Cons: When the fan drops below around 70% speed, it starts exhibiting a very distinct electrical buzz, more audible than the fan itself if it were running at full. Since my motherboard's "SmartFan" speed control function insisted upon trying to run both fans at 60% or below when idling, this got very annoying very quickly. It took an override from SpeedFan or nTune to get the speed back up, whereupon the buzz disappeared. As this happens with both of these fans I have, I'm guessing it's inherent to the design rather than a defective unit.

Overall Review: I ordered two of these for my P180B -- one to replace the rear exhaust and one as a forward air intake. I ultimately ended up pegging the exhaust at 100% and limiting the intake to between 80-100% though the BIOS. This is noisier than I had expected, but both of these running is still only slightly more noisy than a single Tricool.
