There are occasions as an overclocker when you want to shut down the system without turning off the power to other parts of the system, for example the drives and system fans. This is where OC Ignition is really useful.
Hitting the OC Ignition button gives continuous, uninterrupted power to all the motherboard's connected drives and system fans, but not to the CPU. This is useful in 'cold bug' situations when you need to heat the CPU to a bootable temperature, but you'd prefer the fans to keep spinning, reducing moisture build-up.

Overclockers using i-ram drives may also want to maintain SATA power and not risk losing their customized OS install while users with regular SSDs or HDDs also know that frequent powering on and off is harmful to your drives in the long-term.
OC Ignition is also useful in allowing users to pre-test water cooling setups, and even allows case mod demos to be developed without having to fully turn on the PC.

• Powers fans and drives without booting or powering the CPU
• Active fans help to reduce moisture build-up when using LN2
