EK Waterblocks switch between EVGA 06G-P4-4993-KR and 04G-P4-2983-KR, same pcb?

hi

im switching now 2x 980 gtx by EVGA to 980ti also from evga. the pcb looks like the same
can i use old water blocks or rly need the titan x one ?

980ti - 06G-P4-4993-KR
980 - 04G-P4-2983-KR

Not sure...doesn;t look like it at first glance though (caps on the lower right are different as well as the chokes all in that area).

What does the EK configurator say? That will tell you what fits on it.

ekwb configurator said titan x can be switched to 980ti
only that one.

so i need buy next 2 blocks... ah
