Please help sort out my airflow

post #1 of 2
Thread Starter 
System:

4.7Ghz 3770k delided with CLU between die and IHS with XSPC Raystrom WB
GTX 680 with XSPC Razor WB
CM 690 II Advanced case
Gskill Trident X 8gb 2400 DDR3 Kit
Top mounted Xspc RS 240 rad with twin Gelid 12 Wing PWm blue LED fans mounted above rad pushing outside air down through rad
Rear exhaust CM 120mm blue LED case fan
Bottom mounted XSPC RX 240 rad with twin Gelid 12 Wing PWM LED fans mounted to top of rad pushing case air down through rad and out bottom of case
Front mounted Gelid 12 PWM Led 120 x 12mm front intake fan
Monsoon dual bay res with D5 pump

Here is my theory... it is best to feed rad with outside air. So outside air is pulled in through top of case and rad and then warmed air is exhausted out the rear exhaust fan. Bottom rad is fed air directly from front fan then pushed out through bottom of case. Would it be better to have bottom fans mounted below the rad pushing up through rad and reverse from fan to exhaust to reduce buildup of warm air in case or am I over thinking this and should just try to follow normal case airflow pattern of intake of front/bottom and exhaust top/back? Thanks

Don't follow normal case flow theory... because you are water cooling not air cooling. My recommendation is that you perfectly seal the fans that are between the rads and the case and have all of them push air into the case. Make the front fan and rear fans exhaust fans. You are over thinking it a bit but nothing wrong with that at least your common sense put you in the right direction to begin with.
