Ventilator zgomotos sursa smps Mean Well

Recommended Posts

Am o sursa Mean Well SP-320-36 cu care alimentez un amplificator diy. Problema e ca atunci cand pornesc amplificatorul, turatia ventilatorului sursei creste si se aude destul de tare si fiind relativ aproape pe birou la 1m, creeaza un zgomot de fond vag deranjant la auditii.

 

Care ar fi cea mai buna rezolvare? sa scad cumva turatia ventilatorului original sau sa il schimb cu unul mai silentios?

 

Amplificatorul este kitul T1 de la hifimediy, pun si linkul poate specificatiile sunt relevante pentru intrebare.

Depinde cat se incalzeste sursa. Daca se descurca si cu mai putin aer, ai sanse, daca nu...mai greu.In general un ventilator mai mare, da aceelasi aer, dar la o turatie mai scazuta, prin urmare e si mai silentios.Dar nu cred ca sursa meanwell de simensionata pt a fi silentioasa (are componentele subdimensionate: radiatoare si rezistente/trafuri care se incalzesc considerabil).
