Mosfet cooling

post #1 of 4
Thread Starter 
I will be installing my water cooling setup soon and wanted to do something to enhance my mosfet cooling while I am at it.

I own an MSI 790fx-gd70, which I'm told has mosfets that fail at high voltages due to overheating.

I'm thinking about attaching the fans from my old vantec hdd cooler (two 50mm low profile fans) and attaching them to my nb/mosfet heatsink on the motherboard....

The mosfets are under the top 2/3 of that heatsink and that is where I want to attach the fans. Two questions though:

1) I plan on attaching them to blow into the heatsink, is this the best method?

2) Will this make any considerable difference with mosfet cooling in your opinion?

Thanks

Thats not a bad idea and should help. It might not be a bad idea to replace the thermal pad with something decent from frozencpu.

I would attach them so that they blow down onto the heatsinks.
and yes this should help considerably

Cool guys thanks for the info, I ordered this thermal strip. I think it should work great with the fans on it. rep+
