Hi all. I'm installing 6 Noctura fans tomorrow. The white arrows are my purposed placements. Where the question mark is should that be an intake or exhaust?
Fan Airflow Question

I wouldn't fit a fan at the ? position at all, as it will mostly "steal" the intake air and exhaust it before it's had chance to cool anything
Brilliant thank you all. I can either try it out or just return one of the fans. At the moment there are no fans on top and it does get quite hot.
Shame the case dosnt have more mounting options (3 front, 2 top and 1 exhaust).

Single exhaust fan is simply way too little when you have possibly 350w heater GPU dumping all of its heat inside the case.
These "modern" GPU coolers are just off the charts horrible from case airflow aspect.
Also that bottom compartment doesn't improve cooling any, but at most makes it harder.
Would be best if bottommost front fan could just blow in to case unhindered...
It also prevents installing bottom fan to feed fresh air directly into graphics card's fans.

If you had an AIO exhausting through the top of the case that could mean the case exhaust fan would mainly need to deal with the heat generated by the GPU, less so perhaps for the VRM's etc.
My 140mm exhaust fan seems to expel cooler air now that I have such a setup up compared to that of an air cooler.
I didn't think of that when I recently changed to using an AIO.

Yeah it's a Corsair 4000D air flow case. I have perhaps two of the hottest components in it as well the 3800 MSI Suprim X and a 5800x
I've undervolted the CPU and that took it down 10c, with no real performance loss. On Cinebench it goes to 83 max. On Cyberpunk at 4k max settings (97-99% gpu utilisation) it goes to about 83 max for both of these two stock fans.
On a side note I also discovered that who ever installed the Black Rock Pro 4 Fan installed it wrong (I think?) By installing the outer fan as a case fan. I only noticed it come on during intense games (not at all on cinebench). Plugged it into the "System pump" fan for now and will get them to send me the splitter it should have come with to connect to cpu fan port.
So with regards to air pressure there's no benefit of "pushing the air down" on the "?" Label. I thought it might of helped cool the gpu and "push" the air down and back, to the exhausts. I think I was overthinking it
It's six Noctua NF-P12 Redux-1700 PWM fans I've ordered.

I have a case with a very similar layout and an exhaust fan there dropped GPU temps because a LOT of heat now comes out the top of the case. Hand over anywhere at the top of the PC feels like a heater now, this heat was definitely not being expelled as effectively without the extra fan.
I'd do a test with an exhaust fan in that position and see the results. DO NOT USE TOP SLOTS AS INTAKE in any scenario.
I used to think this way myself. But I wanted GPU temps down in this heat so I tried an extra top exhaust 140mm fan. In smaller cases (mine is a full ATX but a compact one) this setup might work much better in practice than it should do in theory.

I tend to agree. Especially when it gets hot, it'll just blow the heat all around inside the case.
What's going on at the bottom? Is there no way of putting intakes down there?
You'll get a lot less dust in there if you can intake more air than exhaust.
There's no screw slots at all unfortunately on the bottom.
Fans all all installed so far so good. 6c off Cinebench (and higher scores) -15c off Cyberpunk CPU and -10c off the GPU at 4k max settings with dlss performance mode on.

I agree also.
Two fans at the front bringing air in. Then one at the back and another near the back on the top for exhaust fans.

@Hostile_18 maybe it is just about angles but it does look like you could need something like this.....
Perhaps those three attached power cables are pulling the GPU downwards..?

I've actually got one that came with my card. It is slightly off, but not by much. I might put it in though, it is a hugeeee card.

I think it is about supporting the slot as much as it is the card.
You only just have enough room with that case, GPU and fan combo.!
Don't think that you could fit an exhaust fan on that CPU cooler, even if one could be attached.
Good job the power connectors aren't at the end for the GPU.. .!

Yeah its not even a small case either, just those two parts are comically huge

@Hostile_18 That looks better. The card seems a little "twisted" but probably isn't.
Well done.
For me....
can't really see the angle of the GPU support etc but it is needed for my long GPU card. I think that the power cables drag it down a little as well as the overall length of the card.
