IO CENTER

You can control the fan speed (semi-passive and performance) and switch between single and multi-rail from within the IO Center software (as long as the PSU is connected to one of your motherboard’s USB headers). Unfortunately, IO center didn’t work well with my test rig (wouldn't display 12V numbers) so I had to connect it with one of my newer systems.

You can also change the language, temperature system/scale and check for updates from the settings tab.
