IMO, blow in better..

I thought is better have both? To blow the cool air in and also suck the hot air out. No?

i mean only for the side panel as u can see in my pic..i wanna make a blowhole there...but not sure whether the air should be blow in or suck out le

Side panel better blow in, and the rear make blow out....

what u wanna use it for ? GC or proc ?

you can test it yourself. for either GC or proc. try both blow in and suck out. compare the temp and then decide

Make a hole in right side...Then the wind suck in from left side =,.=..Ahahha

bette word for it is "intake" and "exhaust".

if you put at the bottom part of the side-panel, let it be intake.

if you put at the top part of the side-panel, let it be exhaust.

thanks very much for everyone's opinion..anymore??

If you look at CM690, they have an intake fan on the side panel. You can have your fan there doing intake

nice tips~
thinking to do it so ~
thx !

Made the blowhole as intake & exhaust heat from the back of your case. Temp. should drop alittle if airflow was good.

for side panel, intake...

hot air goes up, so..top panel will be exhaust

how to know which side is blow in and which side is out ??

blow in for the side panel, suck out from exhaust.

suck air out
suck air in...nuts lol

side panel = blow in
top panel = blow out (hot air rises)

i think most cpu hsf sucks in air and blows it out through the fins..so it'll more logical if the fan above the cpu hsf blows cooler air into the casing and directly to the hsf..

Bro for the side panel make it as an air intake and top for blowhole and instead of 80mm make it both 120mm better maaa....

imo, suck out.... (exhaust system) then inside casing negative pressure, air 'll automatic come in...

juz like u walk in at supermarket toilet... they got exhaust, (prevent smell going out is 1 reason) the other is u dont need air cond in the toilet, coz as u suck out, the air cond will fill in the toilet which is in negative pressure...

so i believe the same theory can happen to casing... if u happen to got only 1 fan. better suck it out
