Reduce the vibrations efficiently & silent operation
AERO-DYNAMICAL DESIGN
Air-inlet with optimal aero-dynamical design reducing noisy air turbulences
Oil surface tension and hydrodynamic pumping forces provided by grooves, no friction, extremely quiet
HYDRO-DYNAMIC-BEARING TECHNOLOGY
We defined HDB to Hydro Dynamic Bearing. An oil seal design that has a higher reliability and advantage than conventional fan motor design.
1. High revolution precision, low vibration noise
2. Fluid seal design provide extremely long life span
3. Surface tension effect, runs more smoothly with no friction, extremely quiet
Fluid seal design is achieved through the use of oil surface tension and hydrodynamic pumping forces provided by grooves. Bend area is centralized oil and prevented oil leakage out of motor (oil leakage is main problem of sleeve bearing, short life time) . Friction between shaft and HDB will be down due to herringbone structure reaction(friction between the metal is disadvantage of ball bearing, noise & waste heat problem). So HDB conquer sleeve & ball bearing disadvantage to become more reliable & quiet technology for Top-notch fan. Such design concept is successful and applicative on HDD, and we can see a reliability application in it.

This review is from: COUGAR CF-V14H Vortex Hydro-Dynamic-Bearing (Fluid) 300,000 Hours 14CM Silent Cooling Fan
Pros: What a great fan for the cost! I replaced the stock Cooler Master fan from the Cooler Master HAF 932 Advanced. This fan blows quite a lot more air, and is much quieter! I really don't hear this fan going.
Case temps didn't really move at all, mainly because I have really good cooling with the 230mm fans in the front and side of the case.
I can see how if this was one of the main fans in a case that it would reduce the case temps a lot vs. other fans.
Includes a few adapters, metal screws with a Phillips head and also some noise reducing plugs to use inplace of the screws.
The fan has an anti-vibration pad on the edges which reduces the noise going into the case.
Lastly the plastic on this fan is very high quality. When putting in the metal screws on other fans, I almost feel like they are so brittle they are going to break! This didn't make any cracking noises when I was putting the screws in. Very high quality fan!
This review is from: COUGAR CF-V14H Vortex Hydro-Dynamic-Bearing (Fluid) 300,000 Hours 14CM Silent Cooling Fan
Pros: I had recently bought three Cougar Vortex fans to replace the fans that came with my Cooler Master CM 690 II Advanced case. The fans keep my rig nice and cool, and they are ultra-quiet
This review is from: COUGAR CF-V14H Vortex Hydro-Dynamic-Bearing (Fluid) 300,000 Hours 14CM Silent Cooling Fan
Pros: This fan is one of my favorite fans I have ever used. I have bought several AF140's but they do feel a little weak and cheesy, not these cougars, they are solid. you can even feel gyroscopic force if you spin it with your hands.
Cons: cons.. um nope
Other Thoughts: not a fan (sorry for the pun) of the orange color. if they added more color options that would be awesome.
This review is from: COUGAR CF-V14H Vortex Hydro-Dynamic-Bearing (Fluid) 300,000 Hours 14CM Silent Cooling Fan
Pros: Great, great product. German engineering at its best. Silent, absolutely silent, great airflow, looks very purdy, cables are well shielded, what more can you want? I bought 1 of these and 4 of 12cm Cougars. All of them are superb.
Cons: I wish Cougar made 20cm! Gdamn it, nothing on the market is any good! All that "megaflow" from coolermaster is buncha *(&%. I have no idea why everyone is recommending that garbage. Have they even tried turning it on and placing a hand behind it? I guess not!
Other Thoughts: Best on the market! Buy these and 12cm too.
