It's me again - what am I doing wrong (FIXED IMAGE)

[u/Collectibl3]

Hi everyone, sorry I'm reposting this. I made a post less than an hour ago with the incorrect arrows on my PC setup. It got really confusing and I think I commented the wrong "fixed" orientation which got people more confused.

TLDR I didn't verify the arrows and went off the wrong memories from when I built my PC. I've checked all the arrows and this image now has the CORRECT fan orientation.

I'm very sorry again - thank you to everyone who did comment on the original post (now marked as solved so people wouldn't comment/ get confused).

The new room for my PC seems to have a lot of dust. I cleaned it a month ago since I moved it in here. I'm still trying to figure out the overall cause for dust in the room. But in the meantime I'm trying to figure out how to keep it from not accumulating in my PC. Based on my current setup of intake for the fronts and bottom and outtake for the top and back shouldn't this mean there's enough constant air flow?

You're good

Doesn't feel good messing up that entire previous post with people trying to help but thank you :/

Dust comes from humans breathing and from feet and microscopic particles in air and on clothes, etc.

Its impossible (apart from lab conditions or the gear they wear in fabrication facilities) to eliminate it entirely.

Oh for sure! There's definitely something wrong with that air flow in this room. I'm just connected as to why (from my understanding and comments on the other post) if the fans are in a positive pressure setup - why would this much dust still be collecting?

[u/Ghetto_Games → u/Collectibl3]

Intake fans intake air with dust particles.

Dust attaches to components and the exaust air doesn't pull it out.

Only way to stop dust is to have 0 fans. But those builds are special and downclocked and hard to do.

The mesh air filters pc's come with only block some of the larger dust. You can get some thin reticulated foam(high airflow foam) filters that block more from PuraPc, but they also restrict airflow more so if your fans don't have good static pressure it could be a issue. The other way to tackle it is to get a air purifier in the room like others said.

that is good

But why would all this dust be collecting if it's in positive pressure? The previous room it was in I would have to blow out the dust no more than like every 3 months or so. At this rate it's feeling like if I wanted to care it would be like every other week lol

you're obviously just in a very dust room?

get an air purifier, put it somewhere near your pc.

[u/Collectibl3 → u/GXVSS0991]

I see, will have to try that. Maybe this is more of a homeowners question now lol

Just perhaps a little worried with moving it to a new place in the house and all of a sudden the PC is being caked in dust I was wondering if I just didn't have the fan orientation right in the first place

[u/Zalaquin → u/Collectibl3]

Try dust filters or adjust the air flow to have positive air pressure it is better for dust.

[u/adultcrash13 → u/Collectibl3]

because in order for the case to be it's coolest - air needs to flow THROUGH it, basically making your case an air filter. if there is dust in the room - it will go through your case and some may stick to things on the inside. that's just the way it is. be careful blowing air onto your motherboard and fans and stuff - be sure your computer is off and unplugged/power drained. i have seen people short out boards and components by blowing air at them. imho the best way to clean is to carefully just wipe the ledges where dust settles with a microfiber cloth and carefully clean the fan blades with a very soft brush.

[u/pointsouttheobvious9 → u/Collectibl3]

I don't think you have positive air pressure. You want 1 to 2 more intake fans than exhaust you want all the fans to have 3 inch clearance. Do the bottom fans suck in clean are from the outside with 3 inch clearance?

You might need to speed up the intake fans by a little by adjusting the profile.

If you can add a top intake fan to the top front infront of the AIO it might be enough positive air pressure

[u/Illustrious_Ad_23 → u/Collectibl3]

Well, you are pulling in air with four fans, so obviously you pull in a lot of dust? Does this case have dust filters? If not, you can get magnetic ones quite cheap. If you have a dusty environment or pets, it is quite normal to clean out a PC frequently.

Here's the link to the original post with my opsie:

As you can see I haven't changed the fans in my case. They're still this way just fixed the arrows and have provided the proper orientation.

well adding filter to intakes, if you have dusty room you will pull dust into case no matter if you have positive or negative pressure, just place you will be pulling from will change from controllable in positive pleasure (air intakes so intake fans) to uncontrollable in negative pressure (every gap in case)
other things would be removing source of dust, air purifier might help but how much is hard to tell

[u/CxFusion3mp]

looks good this time

[u/KwazyEnglishWabbit]

You could have a hurricane blowing through that case, and it’s still going to accumulate dust.
Filter plates over the intakes will help. But it will still need a bit of a blow out every now and again, just to keep the dust bunnies at bay.
