Dependant on your case's configuration, your degree of patience, and for that matter, your luck, the motherboard may need to be removed in order to attach the cooler. Just hold the molded metal back plate in place, lining up the threaded holes on the plate with the four mounting holes, and place the sink down atop a well cleaned processor. Just screw the four screws in via the X pattern, putting just a few turns of the driver between you and the plate, tightening down the cooler until each screw reaches it's threaded maximum.

Just plug the fan in, and you're ready to go for the time being. Thankfully, Spire's promises of low noise operation are founded, and with even full voltage applied to the fan, things stay nice and quiet through the entirety of operation. Unlike Intel's plastic push-pins, the heavy metal screws will never run the risk of weakening, or even melting considering the absurd temperatures that the processors of the day can reach. Making for the home stretch, this cooler is small enough that it can fit underneath the molded side panel ducts, so it will be able to suck the cool, fresh air from outside the case, and blast it over the PWM circuitry around the CPU.
