Silent But Deadly (they are safe, just a cool title)

Wow, I honestly couldn't even tell these fans were turned on when I powered them up. I bought 4 Scythe F and 3 Scythe E because I thought the F's would be too loud for not being on a fan controller.....wow was I suprised. I actually called Newegg that day and returned the 3 lower speed fans because THESE 1600rpm fans were dead silent. I couldn't even tell they were turned on until the Air started to hit my arm. They are fairly powerful and I am in love with fluid bearings now!

The 3-pin wire isn't as long as I would like, but to understand my circumstance I had to buy additional 24" 3-pin extenders.

If you need to plug them into a 3-pin fan controller you will def need extensions...but most fans do.

Don't worry about the price, this fan will last you several computers. By the end of August I will have 1 on my processor heatsink and 7 as case fans.

TOP CRITICAL REVIEW

Good air flow & ability to push against back pressure. Best I've tried in this regard compared to other low noise fans.
Air flow greater than arctic fan 120 models.

Hummm's, humms and humms. Hums connected to motherboard header and hums connected directly to PS. Humm is as loud as the rushing air.

Arctic Cooling 120 fans do not humm and are next best in flow and back pressure of the one's I've tried. I'm switching back to Arctic Cooling fans. Certainly if you have 100db case fans you'll like these, but if you have hummless fans already the new humm you'll dislike. Looks like AC is manfuactured by Scythe anyway (Go to Scythe/contact/fans)

Features
FeaturesEquipped 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.
