Cooling fan

Hello, I have a 1997 accord with the vtec motor. The question I have is about the ect switch, the switch that controls the electric fan. I noticed that the fan hardly ever comes on, so I unplugged the ect switch and closed the circuit with a piece of wire. It started the fans. So my question is should the fans be running more than just once in a while? I can let it idle for 15 minutes in the garage and the fans might kick on. I read that when the engine warms up the fans should start when it's warmed up all the way. Is this true?
Thanks for any help, jwitey.
