square feet must look funny
yes i think so, but u would have to make sure the solder will rise through the through-hole as mich as possible. maybe u can try to find the faulty pin with wiggling them separately
pressfit connections usually are very reliable. if there is a poor connection i would presume that the barrel of the via is broken and a new pressfit connector will not help. maybe putting solder in would help. did you already test for poor connections?
ah well, then it doesn't work proper with 5v unfortunately
usually fans have a min start voltage. u can try if your fan starts at 5v and if the resulting RPM is ok for you, just solder it without any resistor on USB
i would probably do some circuit with a TL431 and FETs, but this also drains some small amount of battery current.
I have never had anything break on Debian.
I use Arch btw.
