Re: In previous models (I think it was the 7070 MFF) the motherboard had different components for the more powerful CPU.
actually you are correct and I think I am wrong. when Dell ships unit with the 90w psu for 35w cpu, heatsink attached to motherboard is downgraded to save power. motherboard heatsink mounting holes are different for the standard vs low power cpu. I have to say Dell did it again (and tricked me).
7050 MFF configurations that was sold with 65W CPU was equipped with 9CTFR type of CPU fan. It have copper insert, thermal conductive pads for power transistors and is rated for 12V working voltage, 14 CFM.
whereas typical 35W system fan is 5V model with 10.5 CFM, one-piece aluminum construction and the mounting screws scheme is different - 4 versus 3.
when you get the unit open it up to look at heatsink mounting config. if it has three and looks like this video https://youtu.be/5mTUTX4QNkg then it is standard cpu fan which hangs over sodimm memory. better verify than guess based on Dell modus operandi.
the heatsink itself may be all aluminum with the three hole config.
on the other hand some unit use a simpler fan that does not cover the sodimm memory.
according to this source the 35w motherboard 35W IPCML-RN/ZB RR02N also uses standard three hole heatsink mount config.

the 90w psu is cutting the bottom line of psu. motherboard is the same but system is cutting other components to save power.
better get the 130w.
you do not need the 180w psu unless unit shipped w discrete graphics.
130 W, 4.5 mm (for 35 W CPU)
180 W, 7.4 mm (for 65 W CPU and discrete graphics)

OK, so my tasks upon upgrading will be:
1. Buy a 130W PSU
2. Buy/get a different cooling system...
Or forget the upgrade...

OK, so the motherboard is the same. Good news.
In previous models (I think it was the 7070 MFF) the motherboard had different components for the more powerful CPU.
Thanks!

this video shows the 7070 MFF with the low power 35w cpu and all aluminum heatsink attached to mobo using 4 mounting holes. Dell OptiPlex 7070 Micro Project TinyMiniMicro Guide - YouTube
