There are a number of contributing factors to why your case fans are so loud. It could be the way the air is moving through them is choppy, they are not secured properly, they are vibrating because they are off balance, or because the ball-bearings are touching something. Many companies combat that last issue by put oil between the ball-bearings and the central rod. LEPA decided the best way is to remove them entirely.

The newest line of case fans from LEPA are the CASINO 4C Advanced, BOL.QUIET, and the VORTEX 88C, all of which have no ball-bearings. Instead, they are replaced with nano-particles to create a self-lubricating, oil-less, near friction-free environment. This means less noise, smoother spinning, and less vibration. LEPA also incorporated the S-Blade design to minimize air turbulence.

More air, less noise, and better performance. What more could you ask for? All of these fans will be available in July 2014 with the BOL.QUIET PWM at $14.99, BOL.QUIET Tri-Speed at $12.99, Casino 4C Advance at $18.99, and VORTEX 88D at $12.99. While not specified, we believe the prices refer to the 120 mm models. YEAH B!%&H! MAGNETS!

LEPA Introduces 4 New Barometric Oil-less Bearing

Fans for Every Build Need

LEPA, the LED fan expert, announces its new series of fans, including the LEPA CASINO 4C Advance; LEPA BOL.QUIET PWM; LEPA BOL.QUIET Tri-Speed and the LEPA VORTEX 88C. The four series feature the patented BOL (Barometric Oil-less) bearing, a self-lubricating design with nano-particles. BOL bearing features for minimal friction operation and is quieter than traditional 2 ball-bearing designs; the special nano-particles are especially applied for using in a high working ambient, with MTBF≧160,000 hours.


The BOL.QUIET PWM fan equips the new S-Blade. The S-Blade composed with an advanced winglet structure, which can minimize the turbulence and stabilize the output airflow. It has LEPA’s modular frame with LEPA logo halo ring, a special design to absorb more air from 4 slides of the frame and enhance the cooling performance. The PWM control leads to a fan speed / silent management via the system setting. LEPA BOL.QUIET PWM is available in 4 x blue or red LED.


LEPA also offers the alternative of non-LED fan for users. BOL.QUIET Tri-Speed allows users to choose performance, silent or ultra silent mode respectively by an extra 7V/5V adapter. It also has the LEPA modular frame with LEPA logo halo ring design and the S-Blades.

LEPA CASINO 4C Advance fan

LEPA CASINO 4C Advance offers 4 colored LEDs (blue, red, green and white) with 5 adjustable light effects, providing the most colorful and splendid lighting show for mod system. Furthermore, its vortex frame concentrates air flow to cool hot spots directly and the patented Barometric Oil-less (BOL) Bearing is used for extreme silent operation @ 88oC ambience. CASINO 4C has combined with PWM function for speed and noise control, the LEPA CASINO 4C Advance is incomparable.


The VORTEX 88C performs silence operation and durability by the BOL Bearing and new “S” shape blade with winglet design. The Vortex frame design concentrates air flow to cool hot spots directly It also provides extremely silent operation with ≧ 160,000 hours MTBF @ 88oC ambience! In addition, all series come with rubber screws to reduce vibration and maintain silent performance during operation.
