Might be too quiet.

Pros: - Quiet

Cons: - Doesn't move much air

Overall Review: It seems like 500 more RPMs would make this fan far more useful without increasing the noise level too much.

Pros: small and quiet, pefect for those small cramped spaces. It comes with an extender cable and a choker to reduce the speed if its' to loud for you but really its not loud at all.

Cons: nothing

Overall Review: would buy again if needed.

18 months without a filter

Pros: - silent
- good airflow
- robust

Cons: - there are no cons

Overall Review: 18 months in dirty airflow without a filter finally killed one. It was so caked I couldn't turn it. Pretty much silent until it failed. I replaced it in kind and will continue to use these fans--they're dead quiet, move a lot of air for their size, and are as robust as anyone could ask.

Noctua Wins Again!

Pros: Quiet, Quiet, Quiet!! I use these to provide direct cooling for the SSD's and laptop drives in my desktop. I used these to replace the fans on the Rosiwell 2.5" to 3.5" bay adapters.

Cons: The 25mm thickness did present some spatial challenges when installing them into the 3.5" drive bays on my Thermaltake Overseer tower. A simple flipping of the caddies did the trick. Not enough to justify an egg reduction.

Overall Review: These fans are hidden, so the LED bling is not required. They are pricier, but their performance, and brutal durability make a Nocuta fan my first choice.

Amazing little fan

Pros: -Small enough to fit exactly into a gap between my GPU cooler and its PCI-E frame
-Very quiet on even high loading
-Came with the silicone vibration damper, works even you have a hard contact using screws

Cons: -A bit expensive considering the performance and price

Overall Review: One of the best small fans for cooling parts like VRM and chipset of mainboard, a finishing touch to a stable system with minimum amount of effort and added noise

These are Outstanding Fans!

Pros: I use these for HP 8200/8300 UDST systems. They are a perfect fit, and MUCH better than the factory fans.
They also come with adapters for other setups!

Cons: None

Perfect fit in small space

Pros: I installed this fan on an embedded cpu in a mini-itx system that is being used as a router. It keeps the CPU at about 31c. I know that this is not a normal CPU cololing fan, but the heatsink on the CPU only allows for a 60cm fan. The PWM works well at keeping things stable and quiet. I have a few Notcua fans in other machines and trust them to work well. With a 6yr warranty I am confident it will last. There is a premium price for these, yet I haven't lost one yet in 5 years. The color scheme is a like a 1970's radio, but it's just a fan so I'm not concerned.

Cons: Nothing yet.
