will help picking out what you need.
For performance between the different blocks, check this out:
For mine I used the EK block and backplate and replaced the thermal pads provided by EK with fujipoly thermal pads. My temps stay at or below 50 degrees C on everything on the board.
For more on Fujipoly pads check here:
Whatever brand you choose to use, you will want to get a good thermal paste (I used Gelid Extreme) for the GPU, and if you want optimal performance pick up some of the good Fujipoly pads for the VRM's
The yellow boxes are your VRM's you will want to put the Fujipoly on. Both front and backEdited by DNMock - 10/20/14 at 2:24pm
