_Pez_ :
Your card temps are very low, are those watercooled?, or what is your ambient temperature?
I allow my room to cool to 72 for gaming. The HAF X Case has a total of ten fans and some of the stock CM fans have been replaced to move bigger air faster.
My cat sleeps up there on top of the tower and it matters not because the rear and front fans shove very large amounts of air through the case across the CPU and straight out taking the heat from the GPU's out.
The side fan is so strong and combined with the big front lower case fan does not allow the lower card to heat up much. It is very cold down there.
Also MSI has the bridges and MB Cooling blocks (Not water blocks) around the CPU up top above the cards.
I can water cool, but these temps off room air of 72 makes it moot.
SSD's produce very little heat as compared to the old fashioned 7200 rpm drives. A small 120 mm excalibur keeps the group of SSD's cool all by itself.
