coolermaster ml120l grinding noise

[bmxblaz]

i just bought a new pc and bought a liquid cooler for my cpu. a coolermaster ml120l. the thing is its making weird grinding noises that come from the cpu block or the tubes. the things 11 days old and i need help. how can i make the grinding noise go away???

That odd, sounds like a problem with the pump...Could be air trapped or the pump is failing...Personally, I would return for a replacement just in case. Most likely air trapped and will go away as others have had this problem on Cooler Master AIO's, mostly it goes away..

thing is its running quietly all the time but every now and then i get this horrible grinding noise. like every 10-15mins.

I dont suppose you can record the sound...If it is a proper grinding sound like material against material, I would be worried, if it is just trapped air against the impeller or something like that, then it is okay and should settle itself after some time...
