Ade - this logic is a bit oversimplified.
You are correct that a larger mass **all things being equal** would take longer to cool than a smaller mass.
The trick is to get a larger heat sink (to absorb IAT spikes) that can shed heat faster and thus can manage average IAT as well.
Larger heat sink is good if it can also shed heat quickly (increased surface area, increased airflow, etc. etc. etc.)
