Standby is not the same as off. If the fans never spin down then your system is generating enough heat to keep them going. If you want to have the fans spin down/off, then turn off the computer instead of using standby.
I never use standby. My system is either running or not. If I need it to do something later (like recording some tv before I get home), I leave it on. Otherwise, when it's not in use, it's off.
