i bought this cooler ZEROTHERM NIRVANA 120mm . First time it had the fan touching the fins on one side. so i rma'd it. Second time i ordered , it had a retention bracket missing. so the cooler is basically useless. SO now i have to rma it again. Seriously do these ZEROTHERM guy's check what they are packing ? all the while q9450 is sitting there doing nothing . only bright light in this time has been the newegg customer service which offered me overnight shipping on both the orders i placed afterwards. hopefully this time they will send a cooler that is not defective .
