[H+][OH-] = 10^-14

Solve for [H+] and solve as you usually would for pH questions.

EDIT: Sorry misread your post, no we don't need to know how to solve at higher/lower temperatures. Though I would imagine it's technically examinable, but they would "step you through it" so to speak, and provide you with the Kw value.
