At first I would have said it was your relay. They are known to get shorts and stay on. But you had that and the sensor changed. I would have to say it's time to trace teh wiring and make sure the wires aren't rubbing somewhere. It's a pain I know. I would start at the fan and work your way back to the relay. Might want to tap on the relay a little to make sure the new one didn't get shorted out by bad wireing somewhere else.
There is also a “cooling fan timer” located inside the vehicle in the driver sideof the dash. This is going to be much harder to diagnose….and I am notsure how expensive a guess that will be to replace. If the relay doesnot solve the problem, I would call your local Honda dealerparts department and tell them your problem and see what they say. Theyshould know which parts fail the most and what they sell the most of.

Cooling fan does not turn off

There is a sensor in line with the top radiator heater hose; When the fans are running after the engine is shut off, try unplugging that sensor to see if the fans shut off.

It may also be the relay this should help you find it....

1991 honda accord lx cooling fan

Some vehicles have sensors that can control the electric fan with the ignition off to keep the heat buildup that naturally occurs right after turning off the engine. This can prevent hard starting that can happen with a hot engine. If it is doing this an abnormal amount, the sensor that is operable with the ignition off may be failing. Before turning off the ignition, check to see if the engine temperature is pushing the 'red zone;' if it is, then the fan operation may be normal but your engine may be running hot.

Cooling system fan not operating. checked/replaced

It's more than a fuse and a relay that needs to be checked.

First do a direct line test feed to the fan motor via jumper wire fed from the battery or fuse box to ensure the motor itself hasn't malfunctioned.

Also you have a temp activation sensor on that vehicle that you'll need to ensure is working properly.
