Question Is this an okay fan-setup?

[sainthawke]

I just recently noticed that the fan right at the back, behind the AIO radiator was set to intake. So, essentially I have had air coming in from the right of the computer from 2 fans (more images in the imgur link), and no real exhaust... So I switched the fan at the back now to be exhaust. So the first fan in the AIO-radiatior-sandwich intakes the fresh air that is intaken by the two front fans, and the fan behind the radiator now exhausts the heat.
Is my thinking here correct?
Here I drew on the image to explain the current setup, sorry for the image being cut off. I hope it's understandable enough that there's another fan there that isn't visible.
Thanks for any advice.

You essentially were in push>radiator<push, meaning that the heat was magically being dissipated courtesy of magic. With your fix, you've now set the radiator fans to pull<radiator<push whereby the arrows indicate the direction the air is taking.

Good job. Though what are you cooling with that measly Corsair 120mm AIO?

Great, thanks for the info there. I'm glad I thought right here.
For the cpu, it's a Core i7 9700K. Bit outdated now I think.

The PSU fan should blow air outside and not inside the case.

But it isnt?

The psu fan is responsible for cooling the psu when necessary. It should play no part in cpu cooling.
On a good psu, it may never run at all.
If I interpret the photos correctly, the psu fan faces the bottom of the case where it draws in cool outside air and exhausts it out the back.

Having both aio fans exhausting heated air out the back is correct.
You should realize that a 120mm aio is not as efficient as a good modern air cooler.
If you have had it for 5 years, it may already starting to fail.

If you have overclocked your 9700K, I would try one of the thermalright peerless twin tower coolers. They are not expensive.

I saw an arrow pointing up that's why I said it.
In any case I know what the power supply fan does.
