Never mind me. I'm adding a fifth video card in the next few days, without adding any more radiators. I'm pushing the upper boundaries of the thermal envelope.

With your planned setup, you should be under 48C, perhaps even 45C. It depends on what fans you use and at what voltage. Plus, all important, it depends on your case ambient temp, which I cannot predict. An air conditioned room would be most beneficial to load temps.
