SN770 Temperatures Question

Ambient temperature is 77F (25C). Idle temps for my (2) SN770 drives are ~38C (1TB mounted lower in the case) and ~42C (2TB mounted between GPU and CPU). Both are running in PCIE 3 x4 (older motherboard). Running a single pass of Crystal DiskMark, I see the temps hit between 55C - 60C. With a 5-pass test I see temps approaching 70C. HWInfo indicates my warning threshold is 84C. I believe I’m perfectly fine and don’t see a load where I would hit that threshold, even without heat sinks. Do these temps look reasonable, including the 4C difference between 1TB and 2TB?
