i want to help subj burner sustain steady 12x dvd burning throughout project burn. burner downshifts to 4x after roughly 50% project completion. i suspect spindle motor driver is being forced to downshift by thermal protective supervisory safeguards.
has anyone actually looked at how high current carrying components are cooled within the unit? i can clearly see a conspicuous sticker “void factory warranty if seal broken”.
from my previous experience with sony playstations, the heat producing chips are provided with a heat conduction pad to the sheet metal housing to dissipate heat. this greatly enhances reliability and longevity. once semiconductors are subjected to elevated temperatures (105 celsius) , tendency is for them to leak current (somewhat “wounded”).
any response will greatly be appreciated.
