Regarding Watercooling pump

[VampMayCry]

Hi guys , just to check with you all about the pump in custom loop. Im using Phobya DC12-400. After using it for more than 1 yr , the pump started to make some loud vibrating sound few days ago . I turned off all the fans already so i can confirm the sound is from the pump. Any idea whats wrong with it?

Does it sound like this?

If yes, probably a worn bearing and time to change. Have you tried emptying the loop and refilling it again?

Not this kind of noise . Its more like a 2.5k+ rpm fan sound . Tried refilling but the sound still there.
