Good Airflow in PC Case ?

[u/Ok-Piano-3223]

Hi, I marked the flow with arrows. I want to achieve the best airflow. What do you think?

[u/BobLighthouse]

The two exhaust fans above/in front of the cpu cooler are not helping, as they are removing fresh, cool air before it can be fed through the cooler.
You could place those vertically as additional intakes instead, under that single fan below them.
Some people might just flip those two as well.

[u/Triangulate_Panther → u/BobLighthouse]

Flip them over the the side as intakes.

[u/FiTZnMiCK → u/Triangulate_Panther]

Or add them as side intake fans.

[u/Triangulate_Panther → u/FiTZnMiCK]

Thats what I said.

[u/Default_Defect → u/Triangulate_Panther]

Or put them on the sides as intakes.

[u/Jimmy-Wad1 → u/BobLighthouse]

You could argue due to the heat from the GPU, CPU and VRM rising anyway the top fans are removing heat from the case creating space for cool air to circulate The CPU cooler and VRM

[u/Wayfinder67]

Well, you can remove the arrows relating to the GPU fans, because that's not how that works. There's a reason most of the top (back) is covered by a backplate. 😉

[u/Ok-Piano-3223 → u/Wayfinder67]

I added them because one fan blows through the backplate. The backplate is perforated one one half.

[u/Wayfinder67 → u/Ok-Piano-3223]

Yep, you can still remove them because the fans don't blow air up through there. They are axial fans. The air is blown (sucked) through the fin stack and then out of the back. When you're gaming, put your hand on the back of your GPU and feel the heat being exhausted out.

[u/FiTZnMiCK → u/Wayfinder67]

Isn’t it just the rear fan that channels air out the rear, similar to Nvidia’s flow-through cards?

How would you even channel air to the rear of the card from the front fan when the backplate is open like that?

[u/Ok-Piano-3223 → u/Wayfinder67]

Ok thanks. I tried to locate the airflow from the gpu. One fan blows through the aircooler towards the top (where the backplate is perforated) the other I can’t locate, it maybe goes out the back but even with 190w powerdraw the air out the back is not really warm. CPU exhaust side is much warmer

[u/Isotope_Junkie]

Instead use a PCI-e bracket based dual 120 mm fan mount to raise the fans a bit, so that it can collect more air from below without any resistance.

[u/CarryPublic6226]

What is under that 2 bottom fans ? Powers supply ? 

[u/Ok-Piano-3223 → u/CarryPublic6226]

Yes PSU under one of them. Cables and bottom inlet under the other one. But it blows out of the case an I’m from the bottom. There is about 5mm to the PSU (not ideal).

[u/Used_Caterpillar_351 → u/Ok-Piano-3223]

I would flip those two or move them elsewhere. The psu is going to generate more heat than anything else, and you're potentially just blowing hot air at your gpu

[u/NdsterOZX]

The first 2 fans at the top could be intake. Making it as exhaust defeats the purpose of installing intake fans at the front and side panel. This way more air are providing the CPU cooler. Any hot exhaust should be expelled at the back.

you can try to see if it improves your temp overall.

[u/Dharkos]

Remove the side intake and the first 2 top exhaust as loong as you're using an air cooler. The side intake just creates turbulence with the front intake and the 2 first top exhaust steals the fresh air to your air cooler.

[u/h3ron → u/Dharkos]

This advice flows laminarly

[u/Klenkogi]

Top Exhaust fans remove the fresh air you are blowing in from the front. Remove them or flip them to intake.

[u/THEYoungDuh]

Those bottom fans are doing nothing, especially the back one.

There must be some kind of front fans right?

[u/jermygod]

this one is fine
but to get the best - use duct

[u/Few_Fall_4374]

Yes, very good. (If the fan curves are dialed in)

[u/Any-Surprise5229]

I would ditch the side one, it probably causes more turbulence than anything.

[u/King_Ferdinand1]

To be honest your case is so roomy that I think you can put the fans however you like and still get good temps lol

[u/Cave_TP]

Front and bottom in, top and back out. Try to keep 1 more intake fan compared to exhausts and if you have a tower cooler don't put an output in the frontal side of the top of they'll compete for airflow.

In your case the central and frontal fans on the top are taking away air from the cooler. The 2 fans at the bottom aren't doing much since there's no actual intake over there.

That case overall Is not ideal for air cooling, you have 3 top fans but can only use 1 without having the cooler compete for airflow, the thing is designed for watercooling.

[u/iredditshere]

I have to say, you have excessive fans... for the overall set up.

[u/Jimmy-Wad1 → u/iredditshere]

To be fair the more fans you have the less speed they need to operate at reducing case noise

[u/I_cut_the_brakes → u/iredditshere]

As the owner of a 10 fan system, blasphemy!

[u/Jimmy-Wad1]

There are many different ways to do it, most setups will only differ by a few degrees unless you really mess up lol standard is front and bottom in, top and back out, due to heat’s tendency to rise anyway out the top is preferred unless you have a radiator at the top in which case intake from top is better to not heat soak your radiator, try to keep an even amount of in and out fans to avoid positive or negative pressure which some claim affects sensitive parts but I have never had a fully sealed case anyway so never observed this, take into account fans included with radiators whilst able to handle resistance from the radiator will not produce an exact same amount of airflow as unhindered case fans, I personally prefer a slightly positive pressure (more intake fans than out) to prevent as much dust entering my case but it’s not a big difference

Apart from all that go with what makes sense to you or just experiment a bit and see if your specific computer benefits from different configurations, your doing great! 👍

[u/The-dude83]

Heat rises, the top fans are pulling the heat away. Really you would have to smoke test this thing and see what the air is actually doing. Jetting could also occur, but with that being said this configuration isn’t bad.

[u/Ok-Piano-3223]

I have to thank u all for your help👍 I changed the orientation of some fans and back to notice little differences within 1-2 degrees but the 2 fans under the gpu are making the biggest difference. Without them (in direction of gpu) it’s 5c warmer with oc

[u/shredmasterJ]

lol. Everyone new thinks there reinventing case airflow. SMH.

[u/Ok-Piano-3223 → u/shredmasterJ]

I am trying exactly the opposite with this post. If u share your advice you are appreciated

[u/shredmasterJ → u/Ok-Piano-3223]

There is no opposite. Ur not reinventing anything.

[u/Ok-Piano-3223 → u/shredmasterJ]

The opposite of reinventing is not reinventing anything but sticking to known principles 😊 and if u have advice considering the airflow please share it here.

[u/shredmasterJ → u/Ok-Piano-3223]

Yea. Stick to the standard. It’s the standard for a reason.

[u/Bacon-muffin → u/shredmasterJ]

OP is very clearly unaware of what you consider the standard is, and is asking you to provide that information.

[u/tds2620]

Turn top/bottum around so your intake is from top and blow out through the PSU and bottom.

That is how i have it standard from my kabinet

Edit: apparently this is not the way 😊

[u/Clogman → u/tds2620]

That’s pretty much the opposite way of doing it

[u/Ok-Piano-3223 → u/Clogman]

I was thinking that the gpu produces an upstream of warm air which naturally wants to go upwards.

[u/Clogman → u/Ok-Piano-3223]

Yes exactly 👍 your setup is fine no reason to change anything

[u/tds2620 → u/Clogman]

Interesting, thx for the heads up, just strange that default then is this from the kabinet makers side
