Question – ThermalRight all-in-one cooling needs 2 connections, i only have 1

i got this Thermalright Aqua Elite 120 V3.
it needs two 4pins connections, one for the fan and another for the pump.
sadly my mb only has 1 CPU Fan connection. anyway for me to get a 2nd connection to power up the pump?
on the mb of my HP EliteDesk 800 G3 SFF… i see empty connections for HLCK (5pins), USB C (5pins), SD READER (11pins), COMA (13 pins), and PS2/COMB (19pins). plenty of USB ports in the back. can i use any of those to power up the pump’s 4pins?
