i will make this simple but one of the included sp120 fans in my crystal 460x rgb sometimes makes a rattling noise when i turn it on ans when it is spinning i shakes like it is off centre. i will look more in to the issue but if the fan is indeed off centre will i need to disassemble my fully functional entire rig just to send the case back to coarsair or can i just send the broken fan. things to note is that the problem may be caused by the fan being pluged into the aio pump header due to not enough headers on my mobo. i also purchased another sp120 could i possibly send that one fan back with the extra fan i gots warranty?
