Should you disable C states in BIOS?

Disabling C-States will prevent your processor from going into a low power state and will significantly increase idle power consumption. Both manual and adaptive are good options regardless of what Gingerbread says. Both are recommended in the official overclocking guides for the 3570k, 4790k, 4690k, ect.

What happens if you disable C states?

The more C states you have enabled, the more aggressively your CPU can throttle down its power usage when it is idle. When it detects computer activity (a hardware interrupt), it will throttle back up to C0 (full power state). If you disable C states, your CPU will be in C0 state all the time.
