@jamageddon: Negative air pressure is great if you enjoy cleaning dust filters every other month. I do not. I switched to positive pressure. Now the case actively pushes dust away instead of inviting it in. Nailed it. #pcairflow #negativepressure #pcbuilding #techtok
Noctua published an article about optimal fan setup. It might help

wow, the nonsense 👌, you need to clean your pc regularly, that's the solution.

flipping the rear unfiltered fan won't solve your problem

the rear fan doesn't have a dust filter so this is not going to help at all

You have no dust filters on your fans. That's why you have dust in PC. The amount of fans you would need to make a negative pressure matter enough to suck dust through cracks is more than you can fit in that case.

Directly opposing fans firing at each other increases turbulence. Bad move

your rear fan doesn't have a dust filter, you will just keep sucking dust

I don't use fans. Zero dust in my PC. It's all in my GPU and I throw that into the washing machine every few months.

these upper ones and front ones should be intake and rear one out, now your hot air stays under the gpu, potentionally damaging it

but the single exaust fan helps taking out the gpu hot air, making in intake wouldn't be worse?

I think the problem is : Why do you have this much dust in your house?!

noctua recommends flipping one of the top fans but since youre using a top mounted aio this is probably the best for temps.

Positive air pressure is the best air pressure

you are causing more turbulence inside the PC which will ruin tempratures. in your case the best option is buying high static preasure and high airflow fans, for example nzxt core 120 has 2.57 SP and 78.86 CFM which will be great for intakes.

Option 2 is not “lazy”. It’s called 💫engineering💫

you've actually created a vortex at the bottom of the case of hot air. You'd be better off flipping the first of your 3 air fans to an intake and putting the back fan back to being an exhaust. That would stop the vortex and also stop the first aid fan exhausting the fresh cold air that has just come in the front of the case

Just have the fans at the minimum cooling necessary. You pc doesn't need to stay at 30c it will work just fine at 60. You fans will last longer less noise and less dust maintenance

How can you be creating a vacuum if you have more exhaust fans… a vacuum would be too much intake no?

positive pressure is good but u also need intake filters, esp. if u have pet hair/ lots dust ❤️
