2.0 V6 possible overheating?

Yesterday happened something strange.

Got stuck in heavy traffic in the city. Was warm weather in Denmark (around 23º) and after some time the engine temperature rose up to 99º (measured on IKE). Then I noticed some smoke coming out of the engine as well as more engine vibrations followed by a significant loss of power.

As the temperature didn't reach 100º at any point, I decided to turn on the A/C in order for the fan to kick in, which in fact reduced the temperature to 90º.

Anyway, I pulled over and turn the engine off, checking the engine bay. I noticed a spill of coolant.

I wait until the engine temperature was around 70º then I started the engine again and keep driving and everything was fine. No spill, no power loss, no vibrations from the engine and the temp around 91º.

Some facts:

The thermostat was changed a few weeks ago for a reinforced one bought in DMGRS. No leaks found so far.
All the 3 speeds of the Radiator fan are working.

Can someone point me the direction of what could be happening?
