I have a fever.

I usually say the expression 'I have a temperature'.

Either way: I have a fever. I have a temperature.

If you say what your temperature is, usually we'd say it: I have a temperature of 102.

Students: Are you brave enough to let our tutors analyse your pronunciation?
The other two answers are correct. Here is still another acceptable way you can say it that uses an idiomatic expression.

"I'm running a fever."

"He's running a high fever!"

Word for word this idiomatic expressions will not make sense to persons unfamiliar with the language. But among English native speakers it is a common expression.
