I just received my X86 within the last week or two, and I have noticed the exact same thing. I’ve never heard this fan turn on once, and I’ve seen temps up ~185 deg F (85 deg C) using OpenHardwareMonitor. Again I understand that the sensor may not be directly in the CPU that controls the fan, but come on, at some point someone has to acknowledge that there seems to be an issue here…
I ordered my X86 off of Amazon recently, and it was the board only with the 64GB eMMC and windows activated. I also ordered the re_case separately and have the board mounted in it.
I finally just got around to checking the Bios and after finding this forum, I’ve gone ahead and changed the fan control setting to “positive” to see if that makes any difference, although when I was poking around in there, I did find under H/W Monitor that it was reading the temp and said N/A for the fan, so not sure if that is N/A because it wasn’t running or if it is N/A as in it doesn’t recognize that there’s a fan…
I’ve also tried unplugging and plugging the fan pin connector, etc.
I’ll be pretty disappointed if I have to return this board just because the fan isn’t working as I haven’t been able to find anything close to a replacement part, which would be preferable at this point…
Edit: After booting up and BIOS change to “positive” and getting a few programs running and raising the temp, I just heard the fan for the first time around 50 deg C. So happy this was figured out!
This really was the only complaint I’ve had about the computer, so now I’m totally happy.
