Viscous fan is fine if you reved it and temperatures went down. It is easy to check though....Stone cold from being left alone overnight. Spin it by hand in the AM....If it spins more than 1/3rd of a turn it is done for. More than 1/2 and it is definitely done for.

Your water pump probably started pissing out the weep hole at the bottom. Easy check if you remove the thermostat, fill up directly into the pump and see if it leaks out.

Always check fluid level #1 item when overheating occurs.
