For every revolution of your crank you will turn your water pump pulley 1.25 times, if I did my math correctly. So, yes, you are overdriving it. If you drive your car on the highway, on a hot day, and then you get stuck in stop and go traffic for 10 minutes or so, does your temperature continue to climb or does it level off at 100-105 and hold there? That's a little high, but not terribly so, and if your engine temp doesn't continue to climb and then overheat I wouldn't worry about it.
