Soon to be 900D build - Page 3

post #21 of 34
why would you have the top rad in push and downward?? should be in pull and as an exhaust. heat rises.

Ideally radiators will intake fresh ambient air from outside the case through the rad for the best cooling performance, regardless of the position / location. 'Heat rises' doesn't matter at all once you have fans directing airflow wherever / however you want it to go.

I had my top rad exhausting outside rather than an intake. But since my case is beside me, after hours of gaming sessions - I can feel the heat especially during summers.

Then I switched to intakes and my case ambient temp increased. And it affected my OC as well (I only have one exhaust).

But I added another fans (exhausting) wedged between my PSU and case an it dropped the temps to my liking.

There's no universal way - you just have to find the right setup for your situation.

One reason is to have cooler air go through the rad as already stated. Yet another is in an attempt to maintain a degree of positive pressure inside the case. I am sure you would agree that would be difficult if not impossible if the rad was in exhaust as the whole aft end of the case is ventilated. I manage to get positive pressure while keeping my fans in the 5-600 RPM range. The rear exhaust fan is simply to give the air some direction so to speak. I'm sure you can imagine 3 different intake sources being rather turbulant

Exactly. I think this will also help with the aesthetics of my build. Can't wait to log this all. Don't think I've seen too many custom painted 900D's. Should be fun.

Just a quick update: The 900D is at painting currently. I'll post some pictures when the case comes back to me if you guys want?

Seems very hard to keep positive pressure with all the vetns and holes in this case smile.gif Would need a lot of tape or things to cover the back of the case

I manage with 10 NF-F12s, barely lol. Then again I keep them at low rpm. If they only made black painters tape lol

More fans blowing in than out is positive pressure, no matter how many vent holes you have. The tiniest advantage in filtered input cfms over output cfms is all the 'positive pressure' you need. It's probably best not to think of it as 'pressure' as much as which direction all the air will be flowing through all the open vent holes. The only benefit to having positive pressure is in dust control, and it only matters as long as all of your input fans are filtered. A single filtered fan on it's lowest speed blowing in if there were no other fans sucking out would be plenty 'positive pressure' to ensure that all air will be escaping out all of a case's open vented holes instead of any unfiltered air being sucked in through them.

Demciflex filters ftw. They even put their filter material on the front panel filter frame for me. No more crappy screen door material. Still get acceptable flow for my needs. Stock filtration on the 900D leaves much to be desired. Then again, for the price I guess that is normal.
