I am curious as well!I bought it used, and first owner claims it was delidded, yes! When I rebuild my T1 (when I finally have some time!) I think I will repaste and double check mounting pressure of the monoblock. Might even go direct die... But right now, not worried about the component temps, just surprised with coolant deltas. But I will test CPU/GPU like @fabio did in his tests to emulate. Won't be apples to apples, because my GPU pulls 250W and CPU 130W, and monoblock vs CPU block, and different pumps and, and and etc
Maybe is the pump flow also?
BTW, my gpu pulls the same amount than yours, maybe even a bit more.
And CPU is set and use till 145W.
