The ultimate in airflow to noise ratio, iXtrema Pro Quiet Fans are the only fans in the industry to be designed with silence and optimal airflow in mind. Smaller, domed motor hub, larger, more dramatic fan blade sweep area, no other fans on the market come even close in performance!
The new Fluid Dynamic Bearings offer better fan life, don't burn up lubricant, and run quieter. One symptom of the note is that the bearing fluid becomes less viscous during disuse, so the fan may run slowly before it is properly warmed up. Regular usage will avoid this problem.
Foward Sweeping Fan Blades
The forward sweeping fan blade design increases static pressure compared to other silent fans and offers better airflow in areas where ventilation is restricted.
Reduced Motor Size
The reduced motor size and conical shape allows for the largest blade surface area of any fan and improves aerodynamics compared to the cylindrical dead-spot of other silent fans.
Rubber Fan Mounts
The silicone-composite fan mounts dampen motor vibration and prevents resonance or so-called "case rattle" caused when fan vibrations reaches the chassis.
Power Connector Converter
The included power connector converter cable lets the user choose to use either standard 4-pin power supply connectors or the 3-pin RPM monitoring capable fan connectors.

Very quiet fan, however it died on me after only two years, and I only run a few hours per day. I notice they don''t spec the MTBF for this fan. Unless noise is super critical, there are probably better choices which will last longer.

I had this fan in use as a CPU fan for approximately eight months. It has now started clicking and has finally stopped. I examined the fan and it has emitted an oil residue, most likely the bearing fluid. The experience of others seem to to consistent with my experience. Definitely NOT woth the price.

Purchased two of these fans for a development server. Within 2 months of installation they began to rattle at startup for 15-30 seconds, but do quiet down after a while. Overall I am happy with their performance, but a bit disappointed with the quality.
Hmm..

One works great and the other makes nasty noises when starting up. I removed fan and found that with the slightest bit of pressure on the frame the fan rubs. Other fan does not rub the same way.
Quiet and moves a lot of air!

This fan really is quiet, and even under the control of Intel''s m/b utilities (runs it @ ~1100 RPM), it still moves a lot of air. The price is kind of steep, in my opinion, though. If you want silence, these fans are great, but if you can tolerate a little noise, there are other thing you could spend $18 on. However, I''m using this in a HTPC, so the less noise, the better.
