Aurora R10, remove the 3.5" caddy to install second front fan?

Just got this machine, and have to confess that initially I was very skeptical of the design (Coming from a more open space Area 51 R2), but the tool-less GPU replacement is growing on me, I am happy with the space saving. 

on cooling, the front intake fan is perfectly located for my blower style 5700XT so no complains (one question, is it possible to link (e.g. fan curve) the speed of the fan to the temperature of the GPU?)

my main question, is it possible to install (even if glued or with two sided tape another) 120mm intakefan where the 3.5in caddy is? has anyone tried it? I think it would be perfect to cool RAM and chipset (I have the AIO for the CPU).
