Hello
i have seen many videos on internet where the same mosfet (nb 3 from top i think ) dies for this series from gigabyte
Anyone has any idea why it is this
Thanks

Give an example video

3080 3090 same problem

Same ic dies seams

I have also noticed something strange with this board. Using a thermal camera shows the 3rd mosfet gets a lot hotter than the others. If the 3rd mosfet is removed, then the 4th mosfet gets hotter.

How can we find the cause of this?

Для начала 2 канальным осциллографом проверьте форму сигнала, его уровень и время переключения в сравнении с другими каналами, медного слоя на плате под ним может быть меньше и он хуже справляется с отводом тепла.

MOSFET #3 from the top right is U6. Using an oscilloscope shows the PWM input and output of U6 to be similar to the other MOSFETs
After much experimentation, the best solution I could find to stop U6 from getting very hot was:

1) Disable PWM8
Remove R611, Install R1114 100k

2) Switch PH7(U6) from PWM8 to PWM7
Remove R1857, Install R1856 0k, Install R1841 3k

After doing that the MOSFETs are heating more evenly. Hopefully that will fix the problem of U6 blowing
