Upper hose is the one I check to see that the engine is warming up and t'stat is opening.
If you have a digital temp gauge I'd consider some grill block. I add/remove grill block so the gauge settles in around 182º F. That's where it seems to stabilize if it gets enough cooling air, but not too much. Other temps result if I choke off too much cooling air, or if I let too much blast through in winter. On a Gen-6 Civic. I suspect yours is same or similar for temperature.

its a 97 civic hatch, havn't messed with grill block before. Going to be somthing i will definately try once i get this vx engine running tip top to compare gas mileage change with other mods. nothing radical like aerocivic, but just some things to squeeze a bit more mpg out.
The radiator fan kicked on very soon after the tstat opened and the bottom radiator became quite hot. I don't have a laser temp gun, but thinking about getting one just for kicks. might help out with autox and reading tire temps to figure out suspension changes between runs.
