Gigabyte GA-870-UD3 MOSFET cooling.

post #1 of 5
Thread Starter 
I currently have a Gigabyte GA-870-UD3 which wouldn't allow me to OC over 4.0GHz or 2600MHz NB without over heating. So I purchased 5 heatsinks.

1 x http://www.crazypc.com/images/cooler...9/hr09full.jpg

My question is - Where do I put them on this board? ()

I know the 'R80' marked chips near the CPU Socket are the MOSFETS but where else should I put these heatsinks?

(Before anyone asks why I randomly bought 5 different heatsinks, I got all 5 for £13 delivered on eBay )

The HR-09 heatsink would probably fit the MOSFET area; by the way the R80 chips are the chokes, the MOSFETs are the small chips above that.
The other heatsinks would be chipset/northbridge heatsinks I think

Thanks for that info about the MOSFETs or I would have had them mounted to the chokes lol.

Yeah, I'm gona replace my nb/sb heatsinks with the big 05's, the 05's can take an 80mm fan on either side in pushpull so should be a good drop in temps and hopefully a more stable oc.

Also, how do i tell what 'Phase' this board is 4+1 etc? See the8 pin power connector in the top roght of that picture? My PSU only has a 4pin and It's running fine, am I missing something here or do I need a different PSU?

It's an 8+2 phase, you can refer to "AMD Motherboard VRM Info" in my sig if ever
