Processors don't cause noise themselves. It will be all about your laptop's fan and cooling configuration. That being said, both of these chips have pretty similar power draws so there should not be a huge difference in the heat load from either of them.

I'm concerned about which one could cause more audible noise during high load. Does someone know? Thx.
