Question Optimal airflow strategy for Cooler Master Q300L V1 with Ryzen 5 5600X and AK400 air cooler?

[cidra]

Hi all, I have the following components:

- Case Cooler Master Q300L (V1)
- Motherboard MSI B550M VDH Pro Wi-Fi
- CPU Ryzen 5 5600X
- Cooler DeepCool AK400 (Not ordered yet)
- GPU XFX QICK 308 (RX 6600XT)
- PSU NZXT C750 Gold (2024)

I know that this case has not an optimal airflow according to many, but that's what I got due to budget and height requirements and it's not possible to refund.

The above is a build for a person that won't ever fiddle with overclocking and wants something that just works. I'm not an airflow expert either, so my question is what could be an optimal airflow strategy for this build, as it can accomodate the following:

- 2 140mm front fans
- 2 120mm top fans (EDIT: Misleading official spec page - Maybe it can actually fit 140mm?)
- 1 120mm rear fan
- 1 120mm bottom fan

Fans are not yet to be ordered. I think we'll go for Arctic P12/P14 PWM due to tight budgt. I already have some spare P12 Slim PWM fans, but I guess that due to them being slim they may be suboptimal for this case. Any brand/model suggestion is highly appreciated.

What do you think? Thanks in advance for your help.
