Hey guys, I've just swapped the superdrive for a Samsung 120 gb SSD wich I'm using as main hard disk with Yosemite + the old 1 tb (no fusion). Everything works fine except two things: 1. the imac boots and after 4 seconds it sleeps automatically. If I wake it up everything is fine and it won't happen anymore. 2. fans won't spin automatically they always stay at the minimum. I did a hardware test and there are no error. If smc fan control I can set the fans to whatever I want. What's the problem? I've connected the dvd sensor to the ssd alluminum case, no problem it detect temperatures. I restored a time machine backup...maybe is it the cultrip?
