The radiator.

Reason: “Thermal energy” (internal energy) is the sum of the kinetic and potential energy of all the molecules in an object. Temperature measures the average kinetic energy per molecule, but the total thermal energy depends on both that average and the amount (mass) and heat capacity of the substance. A hot radiator has much higher temperature and (in a typical situation) far more mass than a small ice cube, so its total thermal energy is greater.

Caveat: if you picked a very large ice mass and a tiny radiator, the ice could contain more thermal energy despite its lower temperature. So you must compare both temperature and quantity of material.
