Hey there,I have a h115i rgb platinum for just under a year and the last week have started doing a rattling noice .Lower lvl of noice on quiet mode and increasing as the rpm go up.Note i have the rad mounted on the top of the case and have tryed already to move it a little bit in case its air and i can hear like a lot of water movement in there that indicates me thats a lot of air.Is there any fix for this or this is the aio pretty much done?
