I have one 4k TB3 display, and my old Thunderbolt Display chained off of that one. The second monitor plus the laptop monitor add up to about the same number of pixels as the 4k.
When I'm on a video call, the CPU fans are consistently on at what I believe is the lowest RPM.
I would classify that as 'not breaking a sweat'. I suspect you might as well. I'm not sure if OP expects to be able to use all of GPU memory using only passive cooling, or if they have something else is going on.
