I got a digital thermometer because these analog ones don't tell me enough...

I set it up on the hot side and left it there for an hour reading... 92.3F
I then tested the cool side of the tank for an hour... 76.4F
Then I finally (dunno why) tested water temperature... 71.2F

My question is this... Is it a bad thing that the hot side reaches temperatures around 93? The cool side remains around 76 while the warm side is a 92... but is this too hot? Is it time to downgrade from 60w to 50w? Or does this really matter as long as she can escape the heat?

Thanks
