Hello! I upgraded my 980ti with a 1080 (Custom loop). I gave my brother my 980Ti but I put the aircooler back on because he did not want water cooling (Small PC - Does not fit), so I have an extra 980TI Waterblock, my friend wants to water cool his 980, is the does the 980 have the same PCB as the 980TI? (It might be a stupid question, but he wants to know)
