How do smartphones that run multi-core cpus stay cool with such a compact design and zero airflow?

Most smartphone CPUs are ARM based, which are designed to run cool and use a small amount of energy.

Per Mhz, those ARM cpus will provide less computational than an x86 CPU of the same speed.  But the power consumption and heat generation will be much lower.
