I have a PSU with 120mm fan. It was placed above the cpu fan and the motherboard. Is it okay to be there?(Retro Gaming casing layout) or should I buy a new one?. It concerns me the air flow and heat. Thanks!
Specs:
Intel Pentium G4560 with stock HSF
Unknown model of CPU case, but it is very ventilated and it's best in air conditioned rooms, Front to back airflow(2 120mm fans)
Sapphire Radeon RX460 2gb OC Dual Fan
Aerocool Rave 600w 80+ True Rated

Likely not a problem.
What is the make/model of your case, and what is your cpu , cooler, PSU, and graphics card?
The psu fan has only one job; to cool itself.
So long as the 120mm psu fan is not blocked, it will do the job.
Even if it has only warm air to work with.

There is a venting for the PSU, as well as my case is ventilated with holes, best in air conditioned room. I am concerned of the PSU air intake(120mm fan facing the Procie Fan) and the Back Fan(Chassis Fan sucking the hot air out).

The case itself I don't recognize the model, but it has full of holes and it's ventilated best for air conditioned rooms. The Retro gaming CPU Layout that the PSU was placed on top of the Motherboard.
CPU = Intel G4560
Cooler = Stock HSF, I have a 120mm back chassis fan
PSU = Aerocool Rave 600w 80+
GPU = Sapphire Radeon RX460 2gb OC Dual Fan

Not to worry.

Your cooling may not be the best, but it should suffice.

Your only rear fan will draw in cooling air from somewhere, I guess the "holes".
I would not worry about the psu unless you hear it's cooling fan ramp up to very high levels.
Aerocool is not top quality but should suffice.
The hottest component in your case will be the RX460.
Just check your temperatures.
If, at idle, your cpu temperatures are around 10-15c. over ambient, then your cooler is mounted well and will do the job.
Under load, the cpu cooler fan will spin up and get noisy.
But do not worry about the cpu. It will shut down to prevent damage if it senses a dangerous temperature. That is around 100c.

On the graphics card, they are built to run hot, and they do.
If you see temperatures around 80c. that is what they are designed for.

If they get too hot, the gpu fans will spin up.
If that does not do the job, the output of the gpu will be reduced to maintain 80c.
