I installed the "Macs Fan Control" App. And 15 minutes ago, it showed the temperature in the "Optical Drive" of 70º C, as well as in the "Platform Controller Hub Die", everything working in "Auto" mode. I changed it to "Full Blast" and it dropped to 45º C, but this way the fans work desperately and make a lot of noise, however it doesn't heat up the iMac very much. I switched to 3000 RPM (a little less noisy) and the temp stayed at 55 RPM. As the ODD fan is defective, it marks 0 RPM.
I have already completed this guide twice. The first "Bake", we were in quarantine due to the Covid-19 Pandemic. But after performing the repair, my computer worked perfectly for 2 years and 7 months. Usually they say it lasts 2 and a half years. I got lucky. Last week, it happened again. I followed the guide again, this time with more security and knowledge, but I came across defective parts due to time. Two of them caused me problems and more work. First a cable from the Airport antenna, the one with the single stripe, broke right at the connector and I had to solder the connector to the cable to try to fix it. I managed, but I confess that I would have liked to change this cable. The second thing, and here I would like some advice, was that the socket where the fan cable fits to cool the ODD (in my case I removed it and put an SSD HD) is defective and now this fan is not working and this worries me.
