Cooling direction thinking

Background :

One of my LSI HBA in rack case dead after I insert disk, the reason was air flow serious blocking after all disk populate, that out of my expectation.

I try increase fan speed and make some air guide, it have improvement but still hot.

Due to need silent and don't want modify things too much, so I haven't add fan anywhere inside. Today I try reverse the air flow direction from back to front. It really impressive, all CPU, add on card, PSU, case in good temperature now, but harddisk have raise ~6C and hot air come out in front now. Anyway I will keep this setting.

 

As most equipment air flow design from front to back, so this will conflict if they places together.

 

Just sharing, welcome have comment.
