Question about going to standby mode

[sdn111]

Hi, I just built a new amd 1ghz with an msipro2a mb. I have two case fans and a hsf and when i go to standby mode in widows, the fans don't shut off. IS there a way I can make the fans go off without shutting down because they are pretty noisy. Thanks
