Salut, merci de ton aide
C'est un PC fixe assemblé, InteCore i5-2500K 4 coeurs, CG AMD Radeon 6870
Concernant le ventilo CPU, à chaque fois que je fais sensors, il est à 0 RPM - pourtant il tourne bien .... problème de capteur ?:/:/
J'ai observé plus attentivement lorsque l'audio plante, la température du PCI adapter est systématiquement en train de monter au delà de 105°, et qq secondes après plantage le ventilo d ela carte graphiquese met à souffler fort et la température en question redescend rapidement. mauvais asservissmeent du ventilo CG ? mauvais driver pour la CG ?
