One suggestion I would make is to remove the paint under the thermal blocks and see if that improves the transfer of heat to the case? The paint will be effecting the efficacy of the heat transferring to the case..Temps started at low 30s and crept up to System at 56C and CPU at 50C.
I’ve had my unit running stable with OPNsense for over 8 days now with no issue (fingers crossed) but the temp does fluctuating between 40c up to 60c. I think this can be improved on, so I’ve also taken up the challenge.. and for some fun tinkering
My plan is to solder the thermal blocks to the actual case and make sure the CPU is touching the thermal block by adjusting the motherboard mounts like someone else in this thread has done.. Started the process today and have stripped the unit down
Sanding with wet and dry to remove the layer of paint and cleaning up the metal...
The Motherboard still has a lot of leftover flux around the components so decided to clean it all off and protect it with a layer of circuit board lacquer..
Will finish it over the weekend and report back if I waisted my time or not
