0.6kWh / 5min * 60min/1h is still 7.2kW. It only needs to handle those 7.2kW of heat loss for five minutes, not continuously, but the power doesn't change.

The power doesn’t change, but you get 12 systems that each need to dissipate 600Wh instead of a single system that needs to dissipate 7200Wh. You can for example partially buffer the heat if you know that you only need to handle that load for a few minutes. It’s much harder to sustain the same energy dissipation for an hour.

According to [1] petrol cars' fan-cooled radiators can dissipate 50kW

Dissipating a mere 7.2kW sounds achievable, by automotive standards?
