Which new CPU/mainboard for mini ITX cube?

[Uneternal]

I'm currently using a Cooler Master Elite 110 case with i7-4790T, Geforce 1050 Ti and 400W PSU and would like to upgrade the CPU and mainboard.
Since the space in this cube is very limited and I enjoy having an almost silent PC, I'd like to go for a CPU that doesn't produce too much heat.
Currently I'm stuck between a few options and need some input from the pros.
My first option was the 10700T or a 9900T engineering sample but also I don't wanna spend so much money. Does a normal 10400F draw a lot more power?
Also even with non-K processors you can lower the Vcore which lowers the heat. But does that also result in less power consumption?
And do the Ryzens generate more heat? I've heard some very different opinions on that.
BTW: I'm only a casual gamer and the system gets mostly used for Premiere, After Effects, Photoshop/Lightroom.

Ryzens are overall more efficient than Intel CPUs these days, especially in wattage ranges like that. Recent T series Intel CPUs act much like their mobile CPUs, so they can consume power far above TDP for short periods of time to reach their boost targets - both of the listed chips are likely to exceed 100W for short term boost.

An i5-10400f wouldn't boost as high and would offer more stable thermals, but in that kind of power envelope something like a Ryzen 5 3600 is a significantly better chip overall. It will drawn some more power (about 10W more for sustained loads) but also perform much, much better. It should also have some room for undervolting to lower power draw further if needed.

What case are you using, and what CPU cooler?

A Cooler Master Elite 110 case and Alpenföhn Silvretta cooler.

AMD 3400GE 35w TDP 4C/8T would be fine for your use.

Oh I didn't know they have energy efficient ones. Where can I buy that one?

They're sadly pretty hard to get. Some people over on the smallformfactor.net forums have bought theirs off Taobao through a shipping agent like Superbuy, but that isn't exactly straightforward. Also, that APU is based on the previous generation Zen + architecture rather than the Zen 2 arch of 3000-series CPUs, so if you want a noticeable performance uptick you could hold off a few months for the upcoming 4000-series (Zen 2) APUs. They haven't been announced yet, but if they follow the pattern from last year they'll be here around August or so. They should also be more power efficient than current offerings.
