Instead of using sleeve bearings, ball bearings or fluid dynamic bearings, the Corsair ML series relies on magnetic levitation to deal with the friction created by a spinning fan. The fans are available in 120mm and 140mm sizes, with blue, red or white LEDS, or none if you prefer. The fans use a 4-pin PWM connection to allow you to control their speed and should be compatible with any case, heatsink or radiator you might want to use them with. Techgage tried them out in a Cooler Master CM 690 III. They are somewhat pricey, the Pro version which ships with rubber mounts more so, with the non-Pro models shipping in pairs. Read all about them in their review.
"I’m a big fan of magnets, they’re just plain cool. Corsair was attracted to the idea of using magnets in it’s latest fans and created the ML-Series. Sporting magnetic levitation, the ML Series fans are meant to be the last set of fans you’ll ever need. Maintaing both high performance and quiet operation, we take the ML120 and ML140 PRO LED fans for a spin."
