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!

These fans feature fluid dynamic bearings (FDB) for long lasting life and quite performance. Available in a variety of sizes, from the tiny 40x40x10mm to the monstrous 120x120x38mm in a wide range of airflow levels.

the silenx advantage.

	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 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.
	Silicone-composite fan mounts dampen motor vibration and prevents resonance or so-called "case rattle" caused when fan vibrations reaches the chassis.

choosing the right fan size.

Use the following guide to choose the fan size that is right for you:

40mm fans are most commonly used for cooling hard drives and 1U rackmount PCs. Often used for additional airflow in cases where they can fit within the 5.25" drive bays.

60mm fans are used as case fans on smaller cases and for heatsinks with processors that use less power. Often times they are used for HTPC cases with slimmer profile.

80mm fans are the most common fans for use with computers. They are useful in a variety of situations, from standard case fans to heatsinks and various other uses.

92mm fans are also used as case fans and heatsinks, though they are not as commonly used as their smaller or larger brethren.

120mm fans move the most air and as such, they are used in systems that have very high power demands. Used on large server cases or on heatsinks with very hot processors.

As always, check with your documentation to see which fan will fit. Note, fans are measured at the edge of the sides, not diagonally!
