opinions please

If a case has a fan on top, will it get better air flow if it blows in or out? I would think out since hot air rises, but I was told otherwise and I want opinions.

I agree, you probably want a case fan on top blowing out. I would have intake fans closer to the cpu if possible.

 

[ManOfKnight]

depends on your air flow...you do not wanna disrupt your air flow...but most likely i would say out...

Here is what I have, don't laugh.

4 front intake 80mm
2 right intake 80mm
2 left intake 80mm
1 left intake 92mm(modded hole is for 120mm)
2 rear exhaust 80mm

Not installed:
1 left 120mm
1 top 80mm

I have to keep the case in a cabinet-my wife runs a daycare so I dont want the kiddies to destroy it. I keep the door open most of the day, but even when its closed I only gain about 3-4c. If I could keep the case out I would not need all the fans. The back of the cabinet is open and I have a window I keep cracked. That seems to help alot now that summer is over.

Oh yea, and I have a system exhaust blower.

you need some more exhaust... so definatley out.

 

[ManOfKnight]

definitely OUT

 

[Rcttexas]

What if I were to reverse the 2 rear fans to blow in, and made my 3 left side exhaust. It might bring in the cool air from the window?

 

[Lt.HMustard]

then the rear fans would be sucking in the warm are from the PSU...

you have fans blowing on the mobo tray? I have never heard of this, explain please .

 

[Rcttexas]

No, The fans are mounted just before the tray.They actually blow on the hard drives. The fan positions are a little weird but the case was a great price at the time.

I put in the top fan, and now my temps went up 3c?????

I guess I need to find 2 120mm fans for the left side. They are positioned to blow right into the HSF.

oh I see what you mean, cool!
