It would be nice to know the mobo in question, but I can safely say that fan at .12A will be fine. You might have a situation that the fan won't spin when the mobo is trying to make it spin slow. To eliminate this, remove any mobo fan speed control and it should spin. There should be a number next to the term CFM, which stands for cubic feet per minute. You may want to compare this number with similar sized fans on Newegg to determine whether it is pushing enough air for you.
