Need suggestions for fan configuration.

[Abir_]

I'm looking to create positive air pressure inside the case to limit dust build up. Looking for fan configuration suggestions.

 

The current fan setup is:

1. Two 120mm bottom intake

2. Two 8Omm top exhaust

3. One 90mm rear exhaust

 

 

The rear 90mm fan came with the case. 120mm and 90mm fans are the Deepcool X fans, with 43 and 21 CFM max respectively, according to spec sheets.

 

Some things to consider:

1. The GPU right above the bottom fans, blocking almost 60% of the two fan lengths.

 

2. The side panel of the PC is mesh. The other side is solid. Front is also solid.

 

 

3. I'm somewhat happy with the temperature, it's not overheating or anything. However, dust build up can be a concern.

 

Is the current setup creating negative pressure? I'm thinking of flipping the rear fan and turn it into intake with dust filters. Any suggestions would be much of help.

 

The case l'm using is Acer U320BM with matx mobo and atx power supply. CPU Ryzen 5 3600 (undervolted). GPU RX 6600. Only one top exhaust is visible in the photo, the second one was installed later.

i mean with this kind of design and no dust filter? Itll happen eventually.

 

You could buy those tack on dust filters though, if you need true dust mitigation. Something like this.
