Default 2008 g35x cooling fans

Radiator fans work on high speed when ac is on won't run without ac on. Have voltage of 5.6 without ac on constantly to both fans with starting temp of 170f all the way to 210f. High speed voltage when ac is on at 13.9. Anyone have knowledge on the subject. I figured I would see a voltage increase as coolant temp increased.
No check engine light with codes so I sorta ruled out any sensor issues. Pwm relay snaps closed when energized and has continuity but don't know how to test more thoroughly.
