2x120mm or 3x92mm for GTX 970 G1 Windforce fan replacement?

Hey guys. My card is old enough that I feel like I don't have much to lose with playing a little but around with it.

So I will replace the stock fans and shroud with some noctua fans just to increase silence of overall build.

What I'd like your thoughts on is; would you recommend 2x120mm or 3x92mm fans over the radiator?
Dba levels aside (120mm would be more silent, I know), do you figure that two 120 mms would provide more adequate cooling versus three 92mm?

Thanks for your time!

Photos of the radiator size/surface makes it easier to get some consensus.

Keeping airflow unblocked and the radiator clean (regularly dusted) will important and possibly more important than the fan size difference. Dust buildup can prevent proper ventilation through the radiator.
