Lian Li PC-O11 Dynamic Case Fan Configuration

[joji]

So I’m about to swap cases and already bought 9 fans plus a new aio which is the nzxt kraken x72. I already have a fan config in mind but I was wondering if it would workout nicely that’s why I’m here to consult some of the knowledgeable people of the forums for a good or better fan configuration

The current fan config I have in mind is having 3 intake fans on top, 3 intake fans on the bottom, and finally 6 exhaust fans on the side where I will be putting the radiator with a fans sandwiching the rad if that makes sense.

All tips and suggestions would be very much appreciated. Cheers!

It would be better if fans on the top of the case are exhaust since air heat like to rise, not fall. So, fans on the top of the case should be the exhaust, fans on the bottom of the case should be intake, and fans on the side of the case should be intake or exhaust. AIO can be on the side of the case or the top of the case.

Better off on the side, because you always want AIOs as an intake, but an intake on the top isn't really ideal. You can cut temperatures by quite a bit when running an AIO as an intake instead of an exhaust because it isn't using already warm air.

What does that have something to do with my post? I never said "must".

Read it and you'll find out. No need to get defensive when I'm pointing something for the OP and not even arguing against what you said.

It is not a Lian Li case, so temperature will be different. This is why I asked "What does that have something to do with my post?"

It can be applied to almost any case, including the PC-O11D...

Hey everyone thanks for all the tips and suggestions, I appreciate it.

I think Imma go with Escorve’s suggestion having 3 fans on top as exhaust, aio on the side as intake, and 3 fans on the bottom as intake.

Hope y’all have a great one! Cheers and stay safe!

One more thing. Do you think my first fan config option would’ve worked out too? Or is it not ideal? It was having 3 top fans as intake, 3 bottom fans as intake, and aio rad on the side as exhaust? Gpu is horizontally mounted which is a rog strix 2080 super if that would be any difference

As I point it out that air heat like to rise up. So top as exhaust, side as intake, and bottom as intake.

Sorry, but I find that it is hard to believe it is always true. I don't expect you to agree with me.

Hot air rises, so top case fans should always be exhaust.

It has very little to do with the case design, it's just simple science:
1. When your AIO is an exhaust fan, it's taking in air that's already in the case, warmer air, and expelling it.
2. When your AIO is the intake, it's taking fresh, colder air from outside of the case.
3. With the AIO mounted on the side of the O11D, the air is still colder and more fresh than using air from within the case.

You can disagree all you want, but it's completely correct and how der8auer actually designed it. The case is designed for liquid cooling, evident by the fact it doesn't support beefy air coolers like the Dark Rock Pro 4, and the side mounting was designed because a lot of cases put glass front panels in front of fans.

So you are saying that a PC case in video here is a lian li then? I'm sorry you make no sense to me.

No. You're just choosing not to listen, it's that simple.
I've literally tested it myself in the PC-O11D, it's hardly any different than in the video because it's not case dependent, it's simple logic. You're using cold air from outside vs hot air already used inside.

This is not what I was did, I couldn't understand what you were trying to say. As I said, top should be exhaust, side should be intake, and bottom should be intake in the first place. A PC case in video is not a Lian Li case which it proved to only one PC case where AIO placement should be. So again, what does that have something to do with my first post here and OP?

This is not always true. There are a lot of case that has a bad airflow, and they don't always have a room for AIO on side/front.

1. In an older comment you said the AIO could be on the side or top as intake or exhaust, but it's just dumb to put it on the top because you're pretty much guaranteed to get worse temperature when an AIO is used as an exhaust because it's using air that's being recycled within the case. Hotter air. And having intake on top is sub-optimal air pressure.

Aforementioned post: "It would be better if fans on the top of the case are exhaust since air heat like to rise, not fall. So, fans on the top of the case should be the exhaust, fans on the bottom of the case should be intake, and fans on the side of the case should be intake or exhaust. AIO can be on the side of the case or the top of the case."

AIO should always be the intake. If the case fits an AIO, it'll work as an intake. When I had a 280mm I had no choice but to have it mounted on top due to the specifications of the O11 Dynamic, and despite being 1 degree hotter in every benchmark I could find compared to the Deepcool Castle 360, the 360 mounted on the side aided a temperature drop of over 10 degrees.

2. You neglected to notice that I said "almost any" case, meaning that I didn't say all cases.

3. It's a simple fact that AIO is always best as an intake, otherwise you're just losing cooling performance. That's what I was pointing out.

This.

It's basic science. You use warmer air, you get higher temperatures, and intake on the top creates air pressure going in the wrong direction.
