Fan's on its way out maybe? To be sure, make sure nothing is obstructing it in anyway. If that's not the cause, guess you can continue using it. But when fan stops completely temps will go high making the system unstable (crashing, etc) & or eventually fail. Cross your fingers it doesn't do it spectacularly
