Summary: I bought this fan after enjoying the quiet 120mm of the same brand. The wire is long and very small gauge. Small could be a PRO because it's easy to flex and route... but could be a CON as it's small enough to be cut or damaged if you're rough with it.
Pros: quiet compared to others. silent up to 50% speed, quiet up to 80% good quality. long wire
Cons: almost loud at 100% speed. sharp fans blade tips, drew blood when I stuck my finger in it :P
Summary: I am using this in a modified PSU case that contains my raspberry pi server I got this to ensure safe overclocking All i wanted from this fan was silence and a gentle breeze with a low operating voltage and it does perfectly I modified the plug to connect this to my breadboard that probably voids the warranty Need a 80mm 2 or 3pin fan?
Pros: Under-volts very nicely, even runs on 3.3v (almost no airflow, but it actually operates on about 25% voltage) Dead silent at just below 5v (running about 4.65v atm) Extremely quiet at 5v (plenty of air at 5.1v, a lot more than 4.75v) Fluid Dynamic bearing so you can use it horizontally 6 year warranty Match my Fractal R4's white/black color scheme (in use less than 1ft away from that)
Cons: Don't need many 80mm fans now days, mostly use 120 and 140mm No molex adapter is included Fan screws are not black
Summary: Replaced some AC AF 8025 PWM fans that were finally starting to get noisy in my HTPC. These fans were amazingly quiet and move plenty of air. The one unfortunate problem I had with them is, the 4-pin plug doesn't send the fan rpm data to the BIOS. There is a separate one-wire plug that you're supposed to plug into a 3-pin header for that to work. I'm using a specail passive heatsink on my CPU, with these fans plugged into the CPU fan header.
Pros: Good price Quiet Moves plenty of air Fluid dynamic bearing give long service life.
Cons: Unusual mounting frame means it won't fit in places a standard pancake-fan would go. Apparently, the 4-pin PWM plug does not send fan speed data to the mobo.
Cons: These fans are far from being quiet. When I was done building this new computer, I left it on the ground about 7 meters away from my main computer. Despite having my corsair headset on while playing a game, all I could hear was the two arctic fans I purchased. They are as loud as your average single fan gpu running at 100%.
