I have two fans on the side of me case and they booth pushing air in, is this good or should they be taking air out. I just thought if they push air in then it will cool the processor and motherboard and i have one at the back that pulls the air out. Someone said that they should all be taking air out and not giving any in.

Also, what is good fan for ur hard drive

Cheers

Hi M8

You've got it right hears the official diagram for the Athlon

It's always better to have more fans sucking air in then out so i would leave it as it is.

Should not matter, if fans are sucking in then air must be getting out somewhere or the inside of your system would become pressurised.

The idea of a fan is to cool the processor, mobo, harddrive etc by keeping the internal temperature of the case from getting too hot so the fans should be blowing cool air in. The vents take the hot air out.
