Switches were available at various temp settings in the size I needed. Probably also true for your car. However I'd go with the oem value as they already did all the experimenting to find out which temp to kick the fan on at. As hondaworkshop suggested, if it's not switching on/off appropriately you might need a new switch.

FWIW -
My first FE mod was to remove the radiator's old mechanical clutch fan and put in an electric one.

Part of the project was to install a LED in the dash that shows when the fan is running. Unless yours is a lot louder than I think, you can't hear it when driving, and can barely hear it with the engine off. Thus the LED. With the LED working for you, you can easily decide if you like the way the auto-switching is doing its job.

I got a green LED already set up for 15V (or 12V??) from Radio Shack for just a few dollars. Other colors were available. If you're an electrical nerd you can probably do it for less than I paid.
