I'm on newegg picking my MoBo that matches up with the processor I'm going to order. But some of the boards have a 8 pin while others have a 4 pin connector. How do I know if the CPU will connect to the board?

I'm guessing that the connectors that you are referring to are the ones on the motherboard that the PSU plugs into for the CPU. This shouldn't have any bearing on the compatibility of the CPU and the motherboard. The newegg add should have a tab for specification for the motherboard that you are looking at and this should list what CPUs will be compatible with the board. You can also just purchase a motherboard CPU combo that they have already determined will work together.

The cable connector that runs from the CPU fan and plugs into the motherboard. I'm finding that some board have a 8 pin, while other have a 4 pin.

it will matter if you only have a 4 pin 12v rail coming from your PSU and the motherboard needs a 8pin.

http://www.newegg.com/Product/Product.aspx...3128068<---8 pin CPU fan connector

http://www.newegg.com/Product/Product.aspx...131188<----4 Pin CPU fan connector

Core 2 Duo E6750 processor.

Does the processor fan connect to the 8 pin or 4 pin connector? Or does that come directly from the power supply?

Neither one of those links produces anything. Please just list the make and model of the motherboards that you are talking about.

http://www.newegg.com/Product/ShowImage.as...0W+Power+Supply

it's a real mess, the power connectors are for the cpu, not the fan/heatsink

as the picture shows they go from the power supply to the motherboard

http://www.newegg.com/Product/Product.aspx...N82E16813128068

Use of a power supply providing a 2x4 12V power connector is recommended by the
CPU manufacturer when using an Intel Extreme Edition CPU (130W).
