So basically I bought a package of six Noctua 120mm fans and discovered that the one in front of my CPU cooler was drawing fresh air out just before it could enter the CPU cooler, so initially I disconnected it. After thinking about it for 1-2 days, I wondered if putting this fan in an intake position would improve cooling.
It turns out I have the same temperatures whether the fan is there or not xdd.
Do you think it's good if I leave it like this or i just disconnect it ?

Looks good.
It’s essentially the most optimal setup. Cool air being pulled in where it needs to be and hot air exhausted out the back. Not starving anything and not blowing hot air back in.
This is what noctua recommends.
Looks like it would help with CPU temps, I think that gpus like these can heat the CPU cooler intake a bit, so def not a bad idea to set it up that way.
Usually cases have a filtered mounting point just under the gpu in the bottom part, I am no expert but I’d guess It would make the air “flow” a little better around the whole system.
I’d test for temps and see if either gpu or cpu needs a bit of help, otherwise I wouldn’t bother, your rig looks siiiiick regardless.
Noctua just put out an infographic for this. However, their top intake was a little bit lower than the top exhaust. I think they used spacers for that.

I have same configuration but my top fans are more apart. If I were you I would probably remove the top intake, it’s too close.
If you really want to be anal about it, set the bottom right fan that’s sending airflow under the GPU to a higher speed setting than the rest, but other than that yeah, this is optimal.
Maybe you could add a shroud and take the top front as an exhaust -> currently your hot air can only escape through the cpu… shroud could solve that… ok, my build has a aio that gets grilled by the gpu… have to switch, aio for intake…
Just because if done carefully this can be achieved without turning off the PC
…I shut mine off
…I’m gonna try it

I just did the same thing in my case. Except with 140mm fans and 2 rather than 3 at front.
Seems to work well. My CPU cooler is a phantom spirit SE. And huge also so wasn’t sure about the exhaust top fan buti can feel hot air being exhausted so I’m thinking it’s better than nothing
When I did this the temps on my 3080ti quickly rose even on idle so I reverted it back to exhaust.
Fan-cy
Seems fine
I would put both top fans as exit.

It’s perfect [according to Noctua](https://faqs.noctua.at/en/support/solutions/articles/101000530852-airflow-guide-next-steps)
that is a blocky boy

Looks exactly like mine!
What graphics card is this? I love the design
Very good
Basically how I have mine set up, never had problems.
Jealous of the Deepcool Assassin 4. Wish I could get it here in the US.
Good.
Poistive pressure is good as it keeps dust out of the case.
Lots of airflow with 5 fans.
G2g.
Assuming there’s a filter on the top, you’d want both fans to push the same way and to either remove the filter or use it if it’s sucking into the case.
The best configuration.
That’s gotta be the lowest clearance I’ve ever seen between the gpu and CPU cooler, I bet you were relieved when you realized it would actually fit
All top and back are for exhaust front are for intake
Objectively correct according to noctua. Seems escpecially good seeing how bulky your CPU and GPU are
Someone is subbed to this sub alright
I don’t have the top fans. Is it okay ?
This is the way. I have this setup minus the exhaust fan at the back and it’s cool and quiet. Those top fans barely need to be moving.
If it’s good enough for Noctua, then it’s good enough for the rest of us.
I am a huge Fan
Very noctua.
Your GPU exhausts out the top. Keep that in mind
One fan in front, one fan in back as god Intended.
Remove the top ones and let it flow front to back. And make sure that the rear one is pulling out at the same rate of the CPU fans.
It sucks…
And blows.
My man measured that fitment with a nasa caliper.
It will work fine – probably the most optimal option.
