My Z's thermo fan stopped working at around 5PM

Drove to city with my mate and noticed smoke was coming out from the bonnet around 11PM. We pulled up into a tow away zone and popped the bonnet, engine was steaming hot! turned out my Celica's thermo fans had stopped working also....
We just squirted water all over and kept refilling the radiator. The engine was at norm temp when the car was continuously driving, but as soon as we hit traffice, we can just see the meter rise...
So at around 11:45PM we hit the western ring road and headed towards Williamstown

with a broken radiator
