Is it possible to choose the *preferred* core?

Greetings!

I have a pretty hot quad-core CPU, and one core is running significantly
colder than others. Under load, it only approaches the idle temperature
for the rest of the cores.

Is it possible to assign all threads to this core by default, but use
other cores when one is not enough? Or maybe even all "heavy" threads,
if having all cores under 1% load is better in terms of temperature than
cramming them all into one core. (I'm not sure if it is.)
