Ok I accidentally posted with nothing so here it goes

 

i vertically mounted my 3080fe in my helios case

 

in order to dissipate the hot air I am putting an 80mm fan behind it attached to back of case to help exhaust out back 

 

i had the idea to place a second 80mm at the other end sucking air i. And creating an exhaust tunnel pushing this air out as well as pulling it out

 

my concern here is this

 

the end fan of the 3080 exhausts directly out 

 

the other fan flows thru

 

if I add another fan at right angle to this fan the blow into each other

 

will this help exhaust or merely create a turbulent mess

 

I have included a picture of the build so far

 

cheers
