i can try to explain =D
Blowing in air with both ways .. |
->H<------bad idea, air trap inside heatsink
not a good idea since air blow in both side means it will escape from the fins through top and bottom and also the top of the heatsink (the top fan mounting area ada lubang) airs goes top nvm since top got exaust fan for CM690 and other case with top fan mounting. but blows down to GC and out from the top the hot air will circulate around the case which is bad. also it also means that ur rear case fan have to be an intake
this method Major NONO
Sucking air out from both ways .. |
<-H->--------bad idea, no air to suck out ( just my imagination)
not really a bad idea.. Correction here... got air suck out. it can come in through the top and bottom fin and the mounting area. but with this top can fan have to be in intake position just like Pekies setup. the thing is....this..[/color]
->hot air blows to the drive bay. u can set up a drive bay fan to exhaust it through the front of ur casing. and the top fan below that area should be removed. the bad thing is. if ur CPU runs really hot.. hot air blows to ur ram and it also become hot as well. worst if u have a ram cooler install. LOL
Sucking air out to rear |
<-H----also bad idea, this one i dunno how to explain.
not very bad but less effective since there will be less friction between air and the fins.
they are can or should be tested... just for the fun of it
but what xelnamikaze listed should be tested out so that everybody can know how they should or can set up their fans
