Hello folks , first time using this forum and i have a question. but first my build.
 
Core P5
Asus -Z170-AR
6700k
32 gig viper DDR4
850 SS drive
Gigabyte GTX 1070 vid
TR2 RX 850 PS
360 plus 120 Rad cooled
 
for know im just cooling the cpu with both rads.
 
i have a question on the rotation of the Riing 12 fans, are they clockwise or counter clockwise.
if clockwise that would mean that they are pulling air thru the rad correct.
 
i cannot seem to find the direction arrows that you normally see on fans.
 
thanks.........Robert
