A fastening assembly used for securing a heat dissipation device to a printed circuit board, comprises a sleeve, an inserting device extending through the sleeve, a spring encircling the inserting device and received in the sleeve, and a supporting device inserted in the sleeve. In one embodiment, a plurality of pins reciprocate through complementary arrays of holes in a base plate and an overlying spring plate biased apart by coil springs located around the periphery of the base plate. The at least one magnet may have a handle moveable between an engaged position, wherein a magnetic flux is emitted through the interface surface of the at least one magnet, and a disengaged position, wherein substantially no magnetic flux is emitted through the interface surface of the at least one magnet. Airflow generated by spinning discs effect movement of the latch out of the latching position when the drive is powered up. The processor is further configured to generate a second auditory signal that includes the first plurality of voice components with the first voice component at least partially suppressed. The composition need not contain ascorbic acid in order to obtain desirable stability.
