Eight years for one here.
Pump -> 360 Rad -> CPU -> 120 Rad -> 2 x GPU -> Res -> Pump
Although just changed the loop and cut out the GPU for a temp new build.
Pump is always at the bottom of the loop and I've always been super careful not to let it run dry, even when filling or cleaning the loop.
I wonder if there's some flow restriction that's making your pump work harder. Like a blockage in one of the rads or blocks.
