I am new to water cooling and I have a ek ddc 3.25 x-res 100 pump + reservoir . I read that high pump speeds with low restriction loops cause ddc pumps to over heat . this is what I have in my loop ( swiftech apogee xl cpu block ) ( x2 ek fc780 gtx ti in sli ) ( alphacool st30 240mm radiator ) ( alphacool st30 360mm radiator ) is my loop considered a low restriction loop ? and if I run my pump at max speed do I have to worry about my pump over heating ? and do I need to get a heat sink for my pump ?
