Making features smaller is far and away the most cost efficient way to make processors faster. It is also relevant to remember fan size and processor design are at least two independent divisions in the same company (Intel, Samsung) and are often two separate companies (AMD, TSMC). Its not like the chip makers arent investing engineers in design.
