Hi what are the size of the O-rings on the late 05 PMG5 quad single pump delphi? Just want to rebuild for the LCS don't know it it leaking.
Not sure but Apple did use a little bit modified version of the DDC style pumps. I'm actually still using one of my old G5 DDC pumps in my fully watercooled PC I bulit 6 years ago. Granted I upgraded the PCB to PWM and to a better Bitspower housing.
