Check your radiator lower hose... if it's cold while the top hose is too than you got a bad thermostat.

Theres a plug by the distributor that controls the fans, I had that wired so they were on when the ignition was turned on, forgot that it looks like or what color the wires are.

The lower temp sensor is on the upper hose housing, and controls the fan operation also via the fan timer. You must check that for continuity. It is supposed to operate up to fifteen minutes, so honda claims when operating properly. If the car is overheating, it's not necessarily due to a faulty fan. But, check that thermistor and also the fan switch itself.
