A quick look inside the pack shows the different mounts as well as your options for how to get the electricity pumping into your new Spire TherMax Pro cooler. You have the option of using the three pin motherboard connector that is attached to the fan or you also have the option of using the four pin Molex adapter.
They have also included a rear slot mounting fan speed controller. Use this controller with caution, as I used the fan controller provided with my heatsink and cooler and it does not work at all. So I almost lost my CPU and motherboard to the gods of overheating. Luckily my motherboard works correctly and it shut down the system when it got too hot.
