Motherboard Explanation lesson
The Intel Z68 PCH had a 6 Watt( I am pretty sure but will have to check) TDP(Thermal Design Power), which really isn't much, but it is enough to require a heatsink, but not a big one. The ones we see on cheap boards, and even on this motherboard have enough mass to hold the 6W and dissipate it without any airflow other than the ambient air. They tend use radiation as their method of heat dissipation.

Here is the deal, that 8-pin connectors just provides a steady supply of 12v to the board, as well as have an equal amount of ground inputs. The CPU's only source of power is this plug, and usually that plug doesn't provide power to anything else, mainly because it pulls such a high amount of power compared to everything, but also to isolate the CPU power from the rest of the system. Because of this there are copper islands in the PCB. Like when you see a mobo maker talk about having more copper, this is where it comes in handy. The ground and power layers in the PCB are copper and they are pretty thick compared to signal layers, in the case of the CPU power, the VRM and CPU power inputs have their own isolated island of copper. From the 8-pin plug to the CPU the copper in the power and ground layers for the CPU are separated from the rest of the components on the PCB. Now when you pull 300W from that plug in the case of a 4.8ghz 3960X, that 300W is a lot of power to pull and transfer through a thin PCB layer. The "thick" layers are actually only millimeters thick if even that. Every mm of PCB length that the power goes through presents a certain amount of electrical resistance, requiring a higher input voltage to get the desired output at the other end when you increase that length due to increased resistance. Never-mind the heat from that resistance. I am pretty sure it can be moved south, but then again the distance is pretty big, and in cases of boards made for overclocking, you would need to have a higher PSU input voltage to maintain 12v at the MOSFETs in the VRM if you drew that connector south.Edited by Sin0822 - 1/19/12 at 11:14pm
