The passage around this formula
Heat removal is fundamentally a problem of area, not of power alone. The quantity engineers actually design against is heat flux, power divided by the surface area it must leave through: . with q'' expressed in watts per square centimetre. Doubling a chip’s power without changing its package size doubles q'' , and every downstream cooling decision in this article follows from trying to hold q'' within what a given cooling medium can actually carry away from that specific surface before the silicon beneath it exceeds its rated temperature.
Learn the underlying idea
A fraction a/b means a divided by b. The top number is the numerator; the bottom number is the denominator, and it cannot be zero.
