Custom case tips

[MrAlpha188]

Hello everybody,

I am building a custom case and I am trying to keep it as small as possible. The airflow will be from bottom to top, and the PSU will be used as an exhaust. I am using 2 140mm fans, but due to the fans' thickness I can only put them either as intake on the bottom or exhaust on the top. The GPU will be really close tot he bottom of the case, so I was thinkg I could put the fans as exhaust and let the GPU fans work as intake.
Would this work? Or should I put the fans on the bottom as intake? Putting 4 fans (2 top, 2 bottom) would make everything a more complicate and I'd try to avoid it as much as possible.

To give you an idea of the power consumption, I am running a Vega 56 Pulse with a 1600X on a ITX motherboard and Wraith Max cooler.

Hope you can give me some ideas

Cheers!

If 4 fans would make everything more complicated, how about one at the bottom for intake and one at the top for exhaust (two total)? 

 

I wouldn't recommend the GPU fans as an intake, may make the fans run faster/more noisy when it heats up.

I also thought about that solution, however if I leave enough thickness to put a fan on top and bottom I might aswell put 4 fans total. If one fan can fit, there's space for another one next to it. Plus, I often see ITX systems with a single/no fans at all. Would it really be a problem if I had 2 exhaust only?

Are you using standard 1"/25mm thick fans, or slim 15mm fans? Slim fans might help

I am using normal 25mm fans. However, having to place 2 fans on the bottom is an issue because I need to design a mount for them, so saving 10mm won't really help that much.
