Summary: I put this to add as an exhaust to my Micro-ATX Cube (Corsair Air 240) because I have SLI'd 680s and they get warm. Works like a charm. SLI 680s + i7-5820k + Corsair H100i = 30C CPU idle, and both GPUs idle at ~50C, 70C at max load.
Pros: - Moves a ton of air for such a small fan - Very quiet, I was afraid and prepared for it to have too much noise, but was very pleasantly surprised
Cons: Surprisingly, none. The cord is a little long for my liking but i zip-tied most of it around the fan itself
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...
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 war...
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.
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 sin...
