Framework have replaced my mainboard and temps are now normal. With the replacement I’ve finished the build which includes custom CPU and ATX cables but, I didn’t mod DC cable other than with a cable tie
I also added a pair of Thermalright TL-8015 case fans and an Intel AX210 (what a pain it is to attach the antenna cables!), and replaced the 6mm standoffs with 8mm.
I finally received my adapter today and can shed further light on this issue.
Firstly, if you have only one cable/adapter then you must use the first Type E socket. The one that’s closer to the M.2 slot won’t work if the first one is empty.
Secondly, the keying is a pretty bad job. You’re right about B plugs not being supposed to go into A sockets. Keying ought to make it impossible to insert wrongly (either mixing generations or right-way-round insertion) but I’m not sure the USB foundation has scored a win here. Key-A sockets have a relatively large gap - between the pin connecting plastic wall and housing - in one corner which is designed to mate with a plug that has a slightly wider metal frame in one corner (which would be too large for the gap in the opposite corner). But the extra width is so tiny that I can well imagine people who have the correct A-Key plug not noticing and successfully inserting the wrong way round. Bad job, USB Foundation.
Thirdly, I can confirm that it does support one type A and one type C USB sockets on the front panel.
Mine never lights up either during normal use of my system.
I ONLY have seen it light up a solid red for spurts to a few seconds, sometimes, while within the BIOS screen. No idea why that would be; wasn’t doing anything in the BIOS that would be behind its activity. But that it had lit at all implies to me mine is not wired wrong.
Since my case uses separate independent plugs for the front panel header pins, that was the biggest pita to install on my build. So really don’t want to experiment to see if I need to reverse polarity from how it’s labelled, but may do it one day.
It’s actually blue and one of the many failures in my 3D design/printing journey I’ll do an orange one when I finally get the thing to clip properly into place
At high revs the fan is audible but the pitch is quite acceptable. I have two exhaust case fans installed as well so the case doesn’t get too hot. The fans are spinning now and all I can hear is noise from the kitchen about 8M away from my office.
As far as experiences, the Framework schematics helped me get most of the modding done before the motherboard arrived to a sufficient degree of accuracy. The only issues I have had with the machine have really been related to the motherboard itself, the dumb PCIe slot not being open-ended limiting options heavily - ended up using oculink + external PCIe dock to get a bit more flexibility, the BIOS being the worst BIOS I’ve seen in my life, much more limited than what a sub-10W chinese stick PC ships, etc.
