my current fans are running at 1400 rpm...

well for the gtx, ive to get a fan controller....

mmmmmmm

You'll need a fan controller anyway tbh, trying to run 6 fans off your motherboard is never a good idea.

I'm not familiar with your rad however adding another with only a CPU in your loop probably won't help you temperatures significantly, at most several degrees (maybe 5). Look at these results by skinnee here. With an i7-920 overclocked using ~270W with 1400 RPM fans all of the rads tested give a difference of about 5-6C between the water temp and air temp. Obviously another rad will help, but not by 10C, at most 6 assuming you achieve a DT of 0C and your rad behaves similar to the ones tested.

Or if your fans are tolerable at full speed, you can run them at full speed directly off the PSU

If your DT is more then 10 Celcius, more raddage will help. If your DT is at or below 5 Celcius, more raddage is overkill.

If your dt is 9, then adding another of same rad/same fans would cut your dt ~ half to 4.5 to 5C at same TDP. If you had 3 rads your dt would be about 1/3 or 3C, (actually a little more than 3C since at lower air to water delta, the rads becomes less efficient).

until you hit a ~2c delta you will see a temp difference by adding more rad to the loop. After switching from just a 360 on my cpu loop to a 360, 240, and 120 I saw a significant drop in temps at load, almost 10C (@4.0 w/ 1.35v). Obviously each extra radiator will bring diminishing returns, but they are still visible.
