Rir Flow query

Good morning

Please excuse the title was meant to be "Air flow query"

I have a "airflow" question, in the picture below I tried my best to indicate airflow, air comes in the front and the "side panel" getting extracted out the Top by a large fan (installed after pic) and a smaller fan at the back, now could I turn the rear fan around to push air in towards the heat sink and let everything get extracted out the top and hopefully providing more/cooler air to the heat sink?

Pic below, thoughts?

He has a different Case to you so id assume his optimal airflow setup will be different e.g he doesnt have bottom fans so his only input would be the front fan

He has a different case to mine but it is still a CoolerMaster, probably an HAF series like yours. The HAF series has a very similar airflow setup, the only difference being the 200mm case fans at the front and top if the case, and the 80mm rear CPU fan. . The HAF series does have the option of a bottom fan or rad.

IMO good airflow creates an overall draft, blowing air in the case upwards over the components that generate heat, from the front to the rear and out. Inside your case needs to be like catching a chill from sitting in a drafty room because someone left a window slightly open. So the fan at the rear of heat sink needs to be pushing air out as part of the draft.

I find with this type of set up, my fans don't need to be running fast to keep things very cool. Even in this warm weather overclocking my idle temp is at 30 degrees, and at load, just pushing slightly above 70, yet my machine is very, very quiet even just using air.
