Hey peeps. I have the swiftech MCR-360 Extreme (20 FPI). Should I go push/pull or just one way? Will I notice more then a couple of degree drop in my loop?

I have a pair of 360 rads in series, Cougar Vortex HD fans in pull only....during stress here's what I get

Water into rad 1 = 27.6 C
Water between rad 1 & 2 = 27.2 C
Water out of rad 2 = 26.7 C

This is with ambient room of 24C, stressing an overclocked 4770k for an hour with Prime95. So each rad only gives you a drop of about 0.4 - 0.5 C in pull...I would imagine adding a fan on the other side would get you another 0.2 C drop per rad? Remember, my ambient and water temps don't differ much, the greater the difference between water/ambient the more difference you will see in temp drops by rads.

NOTE: I also have a pair of 660TI cards idling in the loop. Total water amount in loop is 2.6 L, 100% distilled

Depends on the fans you choice more than anything.

Pretty sure testing has shown that push+pull > push > pull in most situations.
