MOSFET area burned/stained? - Page 2

post #11 of 24
nothing appears damaged at all.. its just heat discoloration from the inductors.. the mosfets dont usually get that hot.. though the inductors will. I have seen this alot on GPU's mostly..put some airflow on those next time you run them!

Yeah what CL3P20 said.
Looks like no cause for alarm but that's def. a sign they're getting rather toasty.

I would say that they are getting rather hot and it would help alot to put these on them.

The board actually has a pretty nice VRM cooler.
I just removed it to inspect the damage.

That board already has mosfet cooling in the form of a large heatsink, with a heat pipe if I'm not mistaken.

MSI takes the cake when it comes to MOSFETs blowing up.
Looking through the forums, Gigabyte has some problems too.

..just because something has a sink on it..doesnt mean its cool. Heatsinks dont just cool themselves..they work particularly good with airflow on them! From the looks of the picture.. this area lacks enough airflow to keep anything there cool.
post #20 of 24
Does the board itself work when used with CPU, etc.?
It might be something else that stained that area

If it doesn't actually turn on or POST (unless CPU power connector is unplugged, then it won't post but might turn on), then the VRMs somehow indeed fried
