Question Best airflow for TT V21

[wjjmjn]

Hello guys, i have thermaltake v21 mATX case. Fans installed 200mm front intake,4x12 on top exhaust and one back exhaust. I'm using it like this for 1 year now. Now i have a new setup with r5 1600 and asrock b450m pro4 they are a bit hot compare to my older intel i5 6400 and h270 mortar. I'm looking for the best airflow. I have enough fans i can add 2 fans on bottom. What are your suggestions

what type of CPU cooler do you have?

Core V21 fan placement options:

front and bottom should be blowing cooler air in.
rear and top should be blowing warmer air out.

if you are looking for new fans, specifications you should look for;
a good amount of air flow; (m³/h) / CFM,
a lower noise level; dB(A),
and the correct power connector depending on your available fan ports; 3-Pin or 4-Pin. 4-pin PWM is the best option for temperature and noise control.

i have installed 3 fans on mobo and 2 on the connector pwm. Now i should add 2 on bottom for maximum airflow? I have stock cooler rn i just bought gammaxx 400 its on the way
