Testimonial: my Trigkey mini-PC works almost 12 hours a day, I use it for many uses. For a few days, it seemed to me that the fan remained at maximum power all the time. So I opened the little box! There was a lot of dust in it (see photos) After a basic cleaning, by blowing with my mouth, I reassembled the whole thing to first discover that the rest temperature had dropped. Phew!
Finally, the processor and the motherboard remain insufficiently ventilated, and both start to heat up again:
around 78°c. Further dismantling is necessary. This next time I will replace the CPU thermal paste. To be continued...
Warning: To remove the motherboard I had to disconnect the WIFI card. This tiny connector is a pain to replace!…
Now a pic:
Good news! After replacing the thermal past, everything returns to normal! 37°C in basic use, the fans are silent.
