Case Fan Exhaust Question

post #1 of 7
Thread Starter 
sup ocn. i have my exhaust fans turned all the way up to their maximum speed. i noticed that my rear 120mm fan blows more air than my top 200mm fan. should i turn down the rear fan's speed to make the top exhaust fan blow more air and is it better that way? thanks.

The age old question;
What is the best fan setup?

Age old answer;
Give it a try, monitoring your temp's before and after, But I personally believe you will find very little difference.
(No insult intended as well thumb.gif )

I have found after filling my case with some serious air moving and some serious quiet fans, that until the room gets above about 33-35degrees Celsius devil.gifdevil.gifdevil.gifdevil.gifdevil.gifdevil.gif I need no more then just my top exhaust fans running at about 50%, which should be about 100cfm in total. Thats right no intake either.

When the room is that hot, I need to start all my fans to combat such ambient temps,

hey thanks for the reply ginger_nuts. i actually have no problem with my temps. i just wanna know the rightful airflow for my case. would it be better if i let the top fan be the master of exhaust? heat rises right?

Yeh hot air rises, use the top as main exhaust, assuming it is quieter. band.gif

the "right" airflow design for your case would be the one that provides sufficient cooling while making the least amount of noise smile.gif

Plug up all the vents except one intake (front/bottom) and one exhaust(at the rear)
put the highest CFM fan you can in the exhaust hole and tada.....

JK JK JK, just play around with different configurations.

hot air goes where you push it. not where the heat wants to...
hot air rises in a case without any fan, as soon as one fan is present the heat goes where you want it
