In the fanfiction, Naruto Sensei's fever could be caused by overusing his chakra in a recent mission.

In the 'Naruto finds a new sensei fanfiction', there are numerous possibilities. The new sensei could have a mysterious past that is somehow connected to Naruto's own family or the Nine - Tailed Fox within him. This connection could unlock hidden powers or knowledge for Naruto.
