Weird CPU Smart Fan behavior

My board is a MSI Z77-g45. I recently installed a new CPU cooler, the Thermaltake Water 2.0 Performer. While setting the CPU Smart Fan in BIOS, I notice that the lower min. RPM I set, the faster my CPU fans spin.

In MSI Control Center, I find that the other two system fans (set to auto) act the opposite and just what I expect them to - the lower the min. RPM (say from 50% to 12.5%), the slower the fans spin.

BIOS is up-to-date. Really hoping someone can enlighten me on fixing my CPU fan settings. Would really appreciate it, thanks.

How do I do that? I don't see the option in the BIOS. There is only the option to enable or disable Smart Fan and setting the target temperature and minimum fan speed (50%, 12.5% etc.)
