Heat Concern between M.2 SSD and GPU?

            I know this is not recent but
since I came across it that must mean it's still findable.   I
came across this searching for issues of having the m.2 in between the
motherboard and the gpu. I have an asrock z170 oc formula, zotac amp extreme
1080 in the main (1st) pcie slot, and a BPX m.2 nvme in the first m.2 slot as I
use it for windows os boot and easy recovery if anything gets blue on the
screen.

Anyways, I ran the AS SSD benchmark program and monitored the temperatures
of the M.2 WHILE I ran a Valley Benchmark on extreme hd presets. I figured
that'd be the most extreme environment that could cause high temperatures on
the M.2 with the GPU and the M.2 being benchmarked at the same time.

 On the specifications for my M.2 it
says Operation Temperature 0 to 70°C and Storage Temperature -40 to 85° C. The
highest temperature the M.2 reached was 73°C and that?�s after running a 3GB AS
SSD benchmark and TWO Valley Benchmarks back to back (the ssd benchmark was
longer than the gpu so I just ran the gpu again). The space between the Zotac
1080 and M.2 has got to be nearly touching, though, I cannot confirm for
positive but it is so close that I thought I might have snapped it in half when
I inserted the GPU on top of it. 
 

With that being said, I do not think the case or the fans would do a whole
lot (not including the hot boxers) being that they are basically on top of
each other and I am pretty sure unless the motherboard is some type of
layered/3D in/out style (like a 4-inch-thick motherboard) that the
situation will be the same on all motherboards with a M.2 inserted into the
slot under a Zotac 1080 amp extreme and most of the larger gpus in general. 
 

To save time, variables include a Thermaltake Overseer Full-Size Case,
a 120mm Thermaltake riing fan at the bottom as an intake, a 200mm case fan on
the side for intake, two 200mm case fans on top as exhaust, a 120mm lepa on the
back for exhaust, and two 120mm Ek-furious fans on bottom cpu
radiator, and a 200mm fan on front for intake. Couldn't live with myself with
empty fan spaces though it does get breezy while I'm at the computer, a little
chilly sometimes.

Can not figure out how to make this look readable, I did the normal indentations and space between paragraphs but that posted as no spaces and just indents. I then pasted in word, pasted on here and now its all spread out. Give up. Also, I used hard disk sentinel to monitor the temps of m.2.
