Any suggestions for my watercooling loop so far?

[ComputerCurious]

So far I am only going to cool three gtx titans (I won 4 but sold one because the benchmarks I saw didn't really have a huge jump and a i7 3970x.
Pump: Swiftech MCP655-B Liquid cooling system pump
Reservoir: XSPC Dual 5.25" Bay Reservoir
Radiator 1 (GPUs): XSPC RX240 Dual 120mm 2x 120mm High Performance Copper Radiator
Radiator 2 (CPU): XSPC EX120 Radiator
Fans: Cooler Master 120mm Silent Case Fan 4-in-1 Value
Please give me constructive criticism and not be a douche because I have the titans, trust me I would've gone 780. Do you think I should add another radiator for the GPUs?

You need far more rad space to cool down triple Titans and a 3970X.

If you havent already, I suggest you read the water-cooling sticky. In particular the section on TDP.

I have been water cooling for quite a few years and can help with some suggestions. Currently I have a i7-3930k and two GTX Titans.
I have a 360 radiator cooling the two Titans and a 240 radiator cooling the i7-3930k. I'm not quite happy with the 240 radiator cooling the CPU so I'm about to change that to a 360, I have the CPU overclocked to 4.5ghz and while the temps are not high , they are higher then I would like.
To cool the three Titans I would use a 360 minimum, the 360 that I have cooling my two Titans is doing a good job and I am happy with that.

One of the biggest concerns to o with the radiators and everything else in the loop are the fans. The fans are very important and you want to try and get high static air pressure fans, not just high CFM fans but high static air pressure ones. I have found that these Corsair fans have a high static air pressure and they come in Performance edition and Quiet edition models.

If your going to be overclocking then you may want to increase the radiators or at least put fans on both sides , one pushing and one pulling.
For your components a 240 min for the CPU and a 360 min for the Titans.
