Gigabyte 770T-USB3 MOSFET cooling

post #1 of 9
Thread Starter 
I think my MOSFETs are circled in yellow, but I'm not really sure. Will it help if I also get heat sinks for the ones circled in red?

Thanks

For me, the ones you circled in red don't heat up. Still, my mobo is rather different, but your yellow ones are what is usually refered to as MOSFETs, so my guess is they are the only ones in need of cooling.

Red chips are the drivers, not the actual MOSFET transistors
The one you heatsink is the yellow ones; if you have spares throw them on the red ones

xd_1771, is there any way to know which 2 out of the 10 are for the memory controller?

One of the chokes is usually marked slightly differently (i.e. RXX instead of RYY); behind that are the MOSFETs directly relating to that choke.

Thanks, repped.

I (hope) I fixed my hot MOSFETs. I took some pictures so that someone else doesn't end up "saving" a bit on a board that might end up failing unless you spend more on some heatsinks. Thanks to all that have helped so far.

I started out OCing with a oem heatsink. When I added a H50, I could cool the cpu much better, but I also took away what little breeze there was on the MOSFETs






I cleaned off the chips and got the little heat sinks ready





Here's the first one on along with the tape on the others



Almost done



I took one 120mm fan and zip tied it so that it blows on the heatsinks



I was a little worried about what the temps would be, but they are 3* lower than before under load and 1* lower at idle. That's my fix. Tonight I'm shoting for 4.2 again, but without the worry of my board failing.

Yeah adding aftermarket cooling usually is what gets a lot of people's VRMs to fail (alongside overloading), as that is basically removing all possible VRM cooling. No way for the heat to efficiently spread and no airflow getting there whatsoever.
