Should Rad be set as intake or exhaust for better temp overall including passive cooling component on mother board like RAM and SSD

I’m planning to do a custom loop on HAVN HS 420 case. I have always thought that its best to exhaust the hot air from rad out of the case asap you avoid having hot air in the case. but i have seen people saying best way is to have read as exhaust to have cool air going overt he rad into the case . So this is what i’m thinking for my loop

1. top 3x140 fan exhaust
2. side 420 rad intake pull config
3. bottom 420 ran intake push pull
4. bottom back 140 intake
5. top back 140 exhaust

this config is recommended by havn for optimal dust management

My thinking is all this i take will have hot air coming into the mother board area and hinder passive cooling for other component . only cool air source is on he bottom back 140 fan
