Witam, posiadam konsole PS4 CUH-1003A płyta SAA-001. Pomimo dokładnego wyczyszczenia konsola przegrzewa sie i wyłącza. Zauważyłem ze wentylator nie zwieksza obrotów. napięcie na wentylatorze 12V sterujące około 0,88V. Podłączony oscyloskop do sygnału PWM pokazuje przebieg Ale sie nie zmienia podczas pracy konsoli.Wentylator sprawny, po odpieciu pinu sterowania i podania 12v dziala na max obrotów. Pytanie co steruje ww. wentylatorem?

Brak schematu. Przemierz multimetrem do którego mosfeta czy układu dochodzi pin PWM. Jest jeszcze zapewne jakiś termistor przy lub pod układem CPU/GPU. Ostatecznie można zostawić na maksa obroty na stałe albo pokusić się o wykonanie własnego sterowania temperaturą na układzie LM317 i termistorze. Najlepiej jednak poszukać podobnego schematu i rozwiązać naprawę zgodnie ze sztuką.
