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 ?

Not sure on the DDC pump interaction with the loop, although I dont think having a low restriction loop would cause issues in particular.

Whether I would call that loop high or low restriction would depend on how you have the GPU blocks configured. In Serial they offer a lot more resistance compared to Parallel.
If you haven't already set up the loop, I recommend having them in Parallel

Although overall, wouldnt worry. If your really concerned with the pump, jury rig some old fan to point at it. I have an old 80mm AMD Stock cooler fan zip-tied to some tubes in my rig to blow air at the mobo VRM's, doesnt need to be anything special.
