7VBA133U and Chassis Fan

Hi,

I have a Soyo 7VBA133U motherboard with a 3 wire fan plugged into the
Chassis Fan connector.

The fan seems to come on intermitently. Is there a feature on this
motherboard that turns the Cha Fan on and off, based on temperature,
maybe?

Is there a way to keep it on all the time (it's a front fan that I use
to cool the HD and I'd like it to stay on permanently)

Thanks,
Claude
