Optionally, some heatsinks use a peripheral power connector for fan power. Route the
fan wires such that they won't interfere with the fan or any other components.

Configure the motherboard jumpers (if necessary). Older motherboards used jumpers
to configure processor and bus speeds, while some newer motherboards use jumpers
to configure integrated video. Refer to the motherboard manufacturer's manual to set
the jumpers, if any, to match the CPU you are going to install. In modern systems, the
processor configuration is done via the motherboard BIOS Setup.

ets or banks first. Note that multichannel boards perform best if modules are installed
