Clutch fan engagement

I noticed yesterday while pulling about 11,000 lbs up a grade the engine got hot, very hot. The clutch fan never engaged where as it used to come on at a certain temp I believe. Would there be a fuse? Or something mechanically wrong with it? To think of it now I never hear it anymore at all. Sometimes on a cold engine it would run until the engine warmed up a bit too. Haven’t heard it in years.
