So my configuration is positive pressure.
7 fans blowing air in and the aio clogs up all the exhaust (apart from the grilles)
If I change the rear fan, so that instead of blowing in, it blows out... I will still have a positive pressure tower, 6 blowing in and four blowing out (the aio has three ML120 fans)
Now, my tower has the following options:
Front 3 fans
Right side 3 fans
Top 3 fans (that's where the aio is)
Rear 1 fan
Currently they are all blowing air in except for the aio which blows all the air out (apart from the grilles)
"Positive pressure system: the positive pressure system is the one that will make the least dust accumulate inside the case. But it's also the one that cools the worst. Since the air is forced to exit the inside of the case, it is necessary that it has grilles that are very unobstructed to the passage of air. Otherwise, the air accumulates inside. The fact is that, this type of cases are usually quite prone to suffer from hot air pockets."
If you load all the air exhaust to the AIO, even if they are 3 fans, the air flow will be quite limited and you will surely have hot air pockets.
In the end you have 10 fans, although we count the 3 of the AIO, but they will not be as effective because there is a lot of resistance for the air to exit through the radiator. But well, I would try to put more fans blowing out than blowing in, that is, I would leave only the three front ones blowing in and the rest blowing out air.Keep doing tests and measuring temperatures, with the same conditions, that is, the same tests and the same ambient temperature.

@_neptunno_ You nailed it, this was exactly what was needed, great contribution.
One thing is missing, in neutral pressure it is also the mode in which less aerodynamic noise is usually generated.
Well, more than nailing it, I put the information that I usually consult to remember how it works, you can't see how important it is to have it clear.
Thanks for the note on neutral pressure
Regards!

As configured, my tower could put the rear fan blowing out air as @defaulser mentions But the fans on the right side are attached to the front ones, I think if I put them blowing out I won't gain anything... Because they will pull out the air that the front ones blow in. Regards

But the fans on the right side are stuck to the ones on the front, I think if I put them blowing air out I won't gain anything... Why would they blow out the air that the front ones blow in
Nobody has said that. Indeed it wouldn't give much benefit.
What neptunno is suggesting is to leave only three intake fans in the front, and the rear and AIO fans blowing out.
It means that on the side you don't put any fans either blowing in or blowing out, in fact you would put some caps that will come to cover the three holes.
He also tells you to do some tests.

@defaultuser originally the Tower comes with a lid on the right side, I put fans inside,( removing the lid and I didn't gain anything )

Yes, of course, the one I'm telling you about.
@clipper said in Mid-high range gaming PC.:

Yes, we already know that, who told you to flip the rear panel, if you had done what I told you, it would have benefited you. Since you posted the rear panel change, I've been telling you to put it out, taking it out.
In fact, my initial idea was only the AIO from the front and roof and rear fans out (all 4)
I don't understand your last post, you're repeating the same thing, are you claiming a supposed bad advice?

No. I never consider advice to be bad

I take this opportunity to remind/refresh that in towers with exhaust at the back and top and more intake at the front, hot air always moves backward and upward, more specifically towards the rear fan and towards the rear-upper corner.
This naturally varies a bit depending on the exact distribution of the fans, but that tendency always predominates.
In most cases the place where proportionally more heat comes out of the graphics card is through the rear fan, simply because of its location.
This behavior only disappears completely in unusual cases, such as when the air enters and exits exclusively through the floor and the ceiling.Attachment:
The rear fan also participates in the ventilation of: mosfets, m.2 drive, graphics card backplate, capacitors and the rest of the upper pcb area, and it can also improve the flow in the ram.
All these components are harmed thermally speaking, when hot air pockets are kept swirling inside the case, and the heatsinks work with a mix of fresh and recirculated/reheated air. -
Well I will follow your wise advice. In this order:
Stress test CPU and GPU as is
Change the rear fan to exhaust
Test CPU and GPU
Mount the AIO mount for pull/push
Same tests.I may make a mount for two 120/140 fans to. Give more air to the GPU but lost to the river...
I threw myself into the custom RL -
Due to lack of time I haven't done anything...
Well, yes.
I have flipped the rear fan and used holy water.
It no longer sounds like a turbine.
The most ridiculous thing is that I read an article about the position of fans with grilles and did the worst thing you could do
When I have time I have many open wars I will comment more.
