What does your datasheet say the operating temperature is?
How does “really hot” compare to the operating temperature?

What is the current draw?
How much power does that current draw produce compared to the expected rated operational power.

What is the operating RPM?
What is the datasheet’s operational RPM range?

I don’t know the answer to your question, but these are the type of questions I’d ask when I’m trying to understand if some component’s behavior is anomalous or operational.
