Is This a Good Setup?

[Zevvo]

Hello guys.

I have been focusing on setting up my case to have positive pressure since I want to reduce dust inside the case as much as possible.

I am still a little confused on some parts like the top of my case, so I made something in Photoshop. Please tell me if you think this would be an ideal setup:

There will be no HDD cages in the front. I will put my HDD and SSD in a OWC Multi-Mount in my 5.25 drive bay.

Now I am debating whether I should have a top back exhaust. I don't know if it would improve temps or just make them worse. But then again, hot air rises, doesn't it?

Thanks for reading.

Yes. Good positive pressure there, and the PSU airflow is separated and filtered. That looks like the Arc Midi case which has open fan slots on the top - small amounts of dust will fall in when the PC is turned off. This isn't an issue though.

Having a 140mm rear-top exhaust would improve temperatures but also decrease the pressure. Generally, the faster hot air gets out, the better the temperatures. But the setup you laid out will easily handle a single GPU (CPU temps depend more on the heatsink you're using).

Thanks for the reply.

I don't know why I didn't mention it, but I do have a Midi.

About the rear-top exhaust, what would you recommend I do? If it produced a little more dust but would help my temps I would be fine with that.

Sorry, I forgot to mention something.

I wanted to know, should I buy higher CFM fans for the front of my case? Same question applies to my rear fan.

Thanks.

Doesn't look much like the positive pressure that I know. My case has 6 fans blowing in and only 1 at the back exhausting, doesn't include the PSU since it doesn't intake cool air into the case.

Yours looks more like the usual airflow pattern, cool air goes in and hot air goes out. Still good though because the main purpose of case fans is to keep the air flowing and if you keep the intake of cold air and exhaust of hot air going, it has served its purpose.

It isn't necessary to get higher CFM fans for the case itself, refer to the paragraph above. I would only change my case fans if I want the same or slightly higher CFM but more silence.

I would buy about 1000-1300 RPM fans if not concerned with noise. Any higher is unnecessary.

Regarding the top fan, don't buy one yet. Do some temperature tests and if you're happy, you don't need it

As far as dust prevention is concerned, any positive pressure will do. It doesn't need to be 6:1 airflow, 2:1 will work the same

Thanks for the reply.

All the info you provided helped me a lot.

I will go with two intake fans in the front, and just one on the rear. I will just wait on getting the top rear for now. The side fan is out because I am going to make a window for it. I am still debating on the bottom intake however next to the PSU. Would my GPU benefit from it or just disrupt airflow?

I haven't got any tests or evidence to show you, but I think theoretically, having the PSU as a bottom exhaust would only disrupt airflow. Having air pulled in two different directions from the GPU sounds like it would only take longer for hot air to exit the case. Of course, you can go through the hassle of testing it yourself...
