Casefan airflow

[Coreper]

ive got a little question concerning the airflow of a casefan:

should it blow air into the case, or out of the case?

here is a little sketch of my pc:

*i also have a 8x8 cm casefan on the side of my case, blowing air into the case

let me know

thanks

Your layout looks about right. Not sure you need a fan at the side. The case fan at the rear should remove air from the case - in at the front, low level; out at the back high level.

but i do have a casefan, so what should be better, letting it blow inside or outside?

is it correct if i think you mean it should blow outside?

Depends where the side fan is, I suppose. If it is lower than the main case fan (the one at the back level with the CPU) then it would be better drawing air into the case. If at the same level of higher than the main case fan it should draw air FROM the case.

Always remember that hot air rises so, cold air (low down) INTO the case, hot air (higher up) OUT.

thanks

i wanted to know where to place the main casefan, not the side fan [or i didnt understand you correctly]

but i think it is right like this:

side fan blows into the case, the main casefan blows out

Yep! In at the bottom, out at the top.
