I finally connected the fan! Last week, when using the GUI and working the cloud with another user, I realized that the Ordoid got crazy warm. So I finally went and connected the fan. I found an old forum entry of someone doing this, and explaining the process: https://forum.odroid.com/viewtopic.php?f=171&t=36030

In order to connect the fan I had to get a JST P4 GH connector (Japanese Solderless Terminal, 4 Pin, 1.25mm pitch, or distance between pitch) and connect the cables to the fans connector. Luckily the person from the forum included images which I could just match since my connector had different colors. For me it was:

Blue -> Green
Green -> Yellow
Yellow -> Black
Black -> Red

Then it was just a matter of rebooting and entering the BIOS and changing the fan speed. This however didn't really seem to work. I checked this by installing the libraries stress and sensors and ran

$ stress --cpu 8 --io 4 --vm 2 --vm-bytes 128M --timeout 10s
$ sensors

The CPU went up to 80 Celsius but the fan never changed speed. I suspect that is because it's a 12V fan in a 5V connector. I will ask Jan Kees if maybe it's possible to draw power from one of the SATA ports, which is what someone in the forum suggested.

Met with Jan Kees today and asked him some questions.

I finally figured out how to do the SSH forwarding, basically it was already set up. I asked him about

(redacted)

Lastly we talked about the fan. I asked if I could just connect to the 12V+ SATA connector, he said it's pretty fool proof. Well he made the calculation without me: I think I broke the computer. It doesn't turn on anymore or light up. Fuck.

Just to confirm, I broke the computer. I will have to find a replacement. This sucks.
