Your GFX has a air handler that blows air out the rear of your case, only to get sucked back into the coil of your H50.
I willing to bet that more than half the people that have the H50 in intake are going to come back later on in the year asking why the temperature of the H50 is getting so high. Its because they have it set up wrong. You got to remember the H50 came out in winter and a very cold winter on top of that. What is working for you now (intake) will not be the same in other seasons.
Try following the laws of heat it will work for you in any season.
Pings, I really appreciate your drawing the schematic, and actually, I should have uploaded two versions -- the one I did for H50 fans in "intake mode" and exactly your version, for H50 "exhaust mode".
Even so, at least on my machine, results are better for intake. Am running two more rounds, without the shroud, both in & out, then will post.
BTW, oddly enough, when folding GTX throws some heat, not major (~56-63 w/Rivatuner Fan CTRL) but some -- CPU temp stays ~40 idle, low 40's if 2 core are Notfreds. I keep the back of the box least 18" from anything solid.
Also, I am not too worried about summer. I will be running A/C 24/7 one we get to March/April here in Palm Springs. Was already 80 today, more like 85 inside my place.
Thanks for the help, learning tons,
