I've been running a evga 780ti on water and just installed a gigabyte 980 on a corsair 750M PSU. Am I in the danger zone?

I've got the 980 at ~65 tdp and the 780ti is at 100.
Settings:
780ti 1230 GPU, 1774 Mem, 1.15v (41 degrees)
980 1500 GPU, 1752 Mem, 1.256v (53 degrees)
Reason I'm asking is I thought I heard the 980 fans sag for a second.
The case is ventilated pretty well
