DELL DIMENSION 4600 NOISY

[ican3k]

Hello,

My Dell dimension 4600 desktop recently developed a humming noise that is aggravating. Sounds t me like the oldi60 cycle hum. What is the best solution to correct this problem.

Are you sure you didnt hear this noise before?

My oldest desktop is a Dell Dimension 4600. Slow but a good work horse.

Regarding the humming; the 60 Hz is the clue. You may be hearing some resonance, and this may be transferring to the case sides which are sheet metal. The 'DELL' logo is embossed in order to provide a stiffening effect.

Try attaching a piece of flat plastic to the inside of the case cover. This will alter the resonant frequency and prevent the case acting as a megaphone for the transformer hum inside the PSU. (Lead self-adhesive automotive wheel balancing weights will work great).

(All electrical machinery using lams will hum).

Yes, it stated about 1 month ago. I did not hear it before that. Thanks for responding.
