Hello friends, I repair video cards for a living, I have a problem with an RTX 3070 ZOTAC GAMING, this card uses (up9512r) and drmosfet (AOZ5311NQI BLN0). The problem is that when you replace the damaged mosfet, the board works properly for 3 to 5 days, then another mosfet fails again, can you help me, what can I do? THANKS YOU |

Try to resolder all the mosfets with new solder |

I would check all PWM signals with a oscilloscope. All of them should look the same. |
