MOSFET area burned/stained? - Page 3

post #21 of 24
Thread Starter 
It's been a while since I've used it, but it does boot.
I think it randomly freezes, though.
Not sure if it was the configuration I had at the time.
The motherboard didn't play nice with the RAM I had.

The mosfets should take 150 Celsius without burning ,if they are properly made .

2-nd picture shows that everything is ok.The back simply discolored due to the heat nothing more.If you can enhance the airflow in the area do it.

Freezing may not be related to the VRM ,if the freezing takes place while doing almost nothing stressful.I would suspect RAM in this scenario first ,not the mobo.If the VRM goes over some threshold most probable the PC will shut off.

vrm's dont produce the same amount of power when hot either... their voltage tolerances/characteristics change as temps increase.
