While prime95 testing is running with my high perf 70W TDP -50mv undervolt profile, pulling 102W @ 230V (impressively here stock and HDplex 250W PSU pull pretty much the same power) closed box with the HDplex sticking out 1-2cm at the back - so to answer my own question, no it does not fully fit inside the case - I’ve a few minutes to add my cents.
First, no complaints at all with the board, fully satisfied, if you’re looking for efficiency I would say 100W TDP is the upper limit, better start looking at 85W TDP or below.
Obviously if you got only the board and another case you’re not reading this thread - if quietest operation is of highest importance to you like it is for me and you do not want any hassle, I would really suggest to get another case - for having all options available go with something that fits a full ATX-PSU, lots of quiet options available there.
For me the space I’ve reserved doesn’t fit anything larger than the Desktop case.
Back in March when I learned about the system I was least impressed with the PSU, an 80+Silver rating wasn’t impressive 15 years ago and that 40mm made me cautious as my opinion was that something like a silent 40mm fan does not exist.
But I also knew with the Framework I would have options - other fan, other PSU, other case, thats all possible - with the other options on the market and pretty much any Mini PC you’re pretty much stuck with the hardware you got.
And I thought 100 Euro just to get in line isn’t much, so I preordered back then - I could always cancel if something better (=potentially quieter) emerges (now we now, it didn’t) or something cheaper (now we know, the other offerings are even more expensive for not offering really more).
What I want is to get the PSU that was promised, with that gradual fan speed control (that’s clearly not happening on my unit - fan speed stays the same no matter if I pull 12W or 220W AC) and the fan carefully selected for smooth operation - I think that FSP is responsible to provide QC and that has failed for quite a few units (and unfortunately this appears to not be the first time in FSP history, there is a recent review for an FSP PSU on Igors Lab and the comments do not paint a favourable picture of FSP QC).
tl;dr: I do not think Framework are really to blame here, they tried to design a solution for the very small case for a reasonable cost - only reason I could see why they didn’t go with a higher efficiency rating to begin with.
What I really would like to know - who thought that a closed box with the only real fan in the system turned off by default when the system idles so there’s no moving air whatsoever could have worked out with that low idle efficiency PSU?
And, why not going with an external PSU - like with every notebook and almost every Mini PC on the market - that I didn’t understand even back in March - heck they could have paired the ATX DC-DC board available from HDplex (a design also known as PicoPSU for at least 15 years) with the 240W brick supplied with the FW16 laptop - and if that is more expensive, make it a “silence enthusiast” option for a markup, I certainly would have ordered that.
I may even try that exact configuration one day.
