This means that maglev fans can run more quietly and efficiently than traditional fans with bearings.

Maglev fans are also known for their durability and long lifespan due to the reduced friction and wear on the bearings.

However, magnetic levitation fans can be more expensive than traditional fans, so the cost may be a consideration for some users.

Overall, maglev fans are a good choice for those who prioritize quiet and efficient cooling.

Which Is Better, QL Or LL?

Because of this, the QL fan has more LEDs on its backside than its LL counterpart. As a result, when the LEDs are on, the fan emits more light on both sides. This fan runs 600-1500 RPM, whereas the one in the QL runs 525-1500 RPM.

Are The QL120 Loud?

In terms of loudness, they are rated between 18 and 26 decibels. Even at full fan speed, the QL120 only produced a maximum noise level of 43.7 dB, which is somewhat louder than the Noctua fans in our office but not nearly as loud as the Noctua fans in our lab.
