There are two mechanisms for heat generation:

1) friction at the contact patch with the track
2) flexing within the tyre

There are two mechanims for heat transfer:

3) conduction through the contact patch
4) air over the tyre (forced convection varying with speed)

For a given track/air temp, increasing tyre pressure will increase 1 and reduce 2 and 3.

reducing the pressure will have the opposite effect.

Obviously there are cross-overs and you can achieve similar temps at different pressures (ride/performance will be different tho). Also, remember that the wheel material may affect the time for temperature stabilisation.
