No airflow + pretty case = more fans?

Hi all!

I've been asking around / searching regarding the Jonsbo UMX6 (I've even posted here once on the "Case" section, sorry if that's redundant)

It looks something like this:

So it's pretty but not airflow friendly. Gamers Nexus would probably roast it - though it might do just that on its own. Fans need to pull fresh air in from a grid at the bottom and push it out from the openings on the side (which are similar to the NZXT 710) + a rear opening, so it's designed for vertical airflow, bottom to top. What seems to suck about it is that the fresh air from the bottom gets warmed by the GPU and the radiator at the top will not be able to cool anything properly + the PSU is at the front so that's one more heat source. But I thought of pulling air from the top AND the bottom, expelling everything at the back, as shown in this magnificent image:

For context: I plan on having a Ryzen 9 5900x cooled with an Actic Liquid Freezer II 280, and for the GPU I have a 1660 Super single fan.

 

What do you think?

Looks like it should be solid. If you're not running incredibly power hungry hardware and pushing OCs on said hardware, you need far less airflow than people often think. A lot of people worry about temps even in the 70s, which is still far below safe max at stock settings. I've had some pretty chunky hardware in both an Evolv ATX (before the Evolv X that brought better airflow) and an S340 Elite, both cases not known for good airflow, with a decent fan set up (for those cases, 2-3 fans in the front and one for exhaust) I never had temp issues.

if you're going to use a bad case then just have some loud and fast server fans in it. The design might be bad but at least it will be moving a ton of air to make up for it

Thank you for the idea, I hadn't thought of server fans. But from what I just saw, a single one of these can produce up to 53dB so I'd get another case before considering that option

Thanks that's reassuring!

If I were in you shoes, I'd probably make it a top exhaust, intake everywhere else.

 

But either way, aside from the CPU getting kinda toasty, it'll probably be okay.

Ah yeah I was wondering whether that'd be a good idea too! I'll see if I do get this case cause it's quite expensive and has no fans included 🤔

Yeah, it makes a sense, since even if you put a filter on the back intake, which I would if I were you, it'll probably be the least obstructed intake.

So the coolest and most volumous source for the hottest component.

And I'd just like the idea of all the air going up in the end.

Yeah it sounds right to have the hot air going up. Thanks for the input ☺️

I would pick u4 plus or u5 over that one. Engineers have taken a look at those and theyve opened up the bottom fan slots so that air can move through more freely.

I looked into it and they do look good + a little more airy! They're both micro ATX so it would mean rethinking my build, also they have no USB-C 😒

The umx4 might be okay tho, but no usb C either...

Oh yeah! I don't know where I saw they weren't. In any case, I have to give it some thoughts.
