currently using raidmax sirius seris casing, found out that my mobo temp still go up still 50..... so i decided to add 1 fan that has a high air flow.....but the question is, shud i put the fan sucking fresh air into the casing or blowing out air from the casing? and put where? i found out only my southbridge is heating up....northbridge has no problem.....and my graphics card temp can go till 60++ >_< sucking air inside will lead to lots of dust inside rite? opinions?

depends on the fan placement
general rule of thumb:
side panel - out or in (depends on preference) top - out front - in rear - out

my front got 1 80 x 80 but i dun think there is air coming in there, coz raidmax design got "door" front panel that blocks the ventilation air in, so, all out is, no in, can ah?
and i need to cool my southbridge + my vga card

extra exhaust fan is more efficient than extra intake fan...
i've read about it before, it's negative pressure or sumthing like that~ dont really remember which thread... in ianho's thread...
so better add up more exhaust

i've found the ori quote QUOTE(E-J@1 @ Dec 12 2007, 08:19 PM) yup, negative pressure is the best but for me i don't want the cfm differences between the intake & exhaust fan differs a lot for my casing:
- i will try to equal the cfm with the intake & exhaust fan
- if the case got two (2) or four (4) fan slot --> will make equal
- we will always get negative pressure --> remember one more fan, the psu fan
- so not much difference in cfm, intake & exhaust fan already equal (in quantity i presume)
- want that negative pressure --> got one more exhaust fan, psu fan that is
- plus the psu fan ain't that fast (or push high cfm), so not that big difference in cfm anyway
- thus less dust will accumulate in time compared to other ppl's casing with hella big difference in intake & exhaust cfm
» Click to show Spoiler - click again to hide... « yup, agree with u on this hot air (from the psu) will be suck by the heatsink's fan to cool off the heatsink btw, which is more hotter?
- Hot air from the PSU (like this project), or
- Hot air from the HDD Bay (like all chassis) --> the air that suck into the case which bypass the HDD bay

most important the air ventilation, make the air flow, then all the heat will go . remember what Bruce Lee said : u put water into a cup, it becomes the cup.  u force the air go in, the same amount of air will go out, togather with the heat as well....
