When I first got the system going I didn't install my front or top cover cause I was worried about airflow and wanted to get a good baseline. My idle GPU/CPU temps were around 30°C and load temps maxed around 45-50°C. As soon as I installed the front and top cover, my idle temps rose to 40°C and load to just over 60°C. The top cover in particular is very restrictive, and causes a lot of ambient heat to make its way back into the case. Mid-game, as soon as i took the top cover off my temps dropped within a few minutes back to my baseline average.
It's tempting to hide fans up top for a low profile push/pull configuration, but it's just not worth it unless you remove the top cover. You'll have too much air pressure up top and you'll be creating a vicious heat cycle back into your case.
If you have not sealed the radiator tray to stop from above back down into case you are not going to run cool.
Fans need at least 40mm clearance to have even a chance of flowing air. A 140mm fan has an airflow area of 144sq cm . A 140mm circle 40mm tall has an airflow area of 175sq cm. If there are 2 fans side by side, 1/4th of each fan flow area is compromised and we have 132sq cm airflow area. 3 fans in a row means center fan only has 1/2 of this airflow area open .. that is 88sq cm airflow area to the fan's 144sq cm.
But the bottom line here is if I can cool a email@example.comGHz and KFA GTX 770 LTD OC and not hear it 4 feet away from me the Enthoo Evolv ATX is definitely a cool and quiet case.
And I still love your rigid tubing layout!
