Features

Features
Equipped with Genuine S-FDB Bearing
This fan is equipped with genuine S-FDB (SONY Fluid Dynamic Bearing) made by SONY corporation.

Market Leading Low-Noise Level
S-FDB technology drastically eliminates the friction between the bearing and the shaft which makes this fan nearly inaudible to human ears. Additional suction magnet optimizes the magnetic force balance within the rotor to achieve the absolute silence. To further achieve the absolute silence, the fan is equipped with the Linear drive IC for reducing electromagnetic noise.

Outstanding Long Life of 15000 Hours
"S-FDB" structure allows the fan to last up to 150000 hours.

Anti-Shock Ability
Conventional ball bearing carries a point contacting structure for the rotation, which gives point supporting situations at dropping impact to damage ball bearing surface which could cause irregular noises. The S-FDB carries a surface contact mechanism for improved anti-shock structure, which is 5 times stronger than the conventional ball bearing.

5 out of 5 eggsWhisper quiet with decent airflow

Pros: There is the never ending battle to find the perfect fan. One usually has to pick 2 out of 3 with fans: Quiet, Airflow, and Price, but I'll dare say with these you can come darn close.

+ Whisper Quiet
+ Decent air flow
+ Good price considering how quiet they are!
+ The S-FDB is sexy quiet + no wear and tear

Cons: - Hard to find a decent replacement when these are out of stock :-/

Other Thoughts: You'll want to spend the few extra minutes to make sure your case airflow pulls in cold from the bottom and pushes out hot air at the top.
e.g.
Rig setup -- Phenom 955 BE, 5770 XFire, port-side fan in pull config, blow-hole fan in push config, keeps everything cool.

Only pseudo con is that NewEgg no longer stocks them, nor lists the last-known-stocking price! C'mon NewEgg, let readers "vote" on what a good replacement would be, and link to something in stock.

4 out of 5 eggsGreat quite fan, but less airflow than advertised.

Pros: -very quiet, almost inaudible. Definetly not going to be the loudest component in your case
-Solid construction
-comes with 4pin to Molex adaptor

Cons: - Marginal amount of airflow. I dont think this has 33.4CFM

3 out of 5 eggsReplaced very quickly

Pros: Large
Its a fan; it moves air

Cons: Loud
Expensive

Other Thoughts: Very quickly replaced with a Cooler Master fan that had a larger CFM and made less noise. Not a bad fan per say, but for the price, you can definitely get a better option

5 out of 5 eggsPerfect. Two years running.

Pros: Running just as well as new, after more than two years. There's been no change in speed or noise.

I love the fluid dynamic bearings, and the fan speed is ideal for decent air flow and whisper quiet operation.

This is my top pick for a low RPM 120mm.

Cons: This fan won't be for everyone. It is extremely quiet, but it's not much good for a rig with a 1000 watt power supply!

Other Thoughts: This fan is used daily for hours, with multiple stop/start cycles each day when entering sleep mode. It's a case fan in a very low powered ultra quiet AMD rig; initially a 5050e, now a quad core 610e system. Users rave that it never gets hot, and they can't hear it!

Second review. See my first review 2jun09.

4 out of 5 eggsExactly what I wanted

Pros: Very Quiet - These have noticeably lowered the audible noise of my case. This means less noise pollution while I listen to my music or enjoy my movies.

Cons: My setup does run warmer now, as I expected it would.

Other Thoughts: They dont move as much as as previous fans, but they are a great deal quieter and since I had some room to give on cooling and don't overclock, I'm happy with the trade-off. All 4 fans were fully functional

5 out of 5 eggsGreat fan!

Pros: Virtually quiet. Fits perfect for the rear 120 mm opening on an Antec 300 case.

Cons: Absolutely none so far after 1 month of full-time use.

Other Thoughts: I was looking to replace the default Antec 120 mm fan that came with my 300 case. This unit can be controlled by the motherboard and will let you track fan speed. Excellent!

5 out of 5 eggsQUIET (no, really!)

Pros: A nice strong summer breeze worth of air flow, at barely any noise at all! Way too many fans call themselves quiet and then end up sounding like a blow dryer. This one really IS super duper quiet!

Cons: Only rotate at 800rpm, so the airflow is not a wind tunnel, which is fine for HTPCs, but I don't think I'd put one of these in a decked out gaming rig.
