My fans wont turn on

Were you disconnected from power before the install? Any liquid damage possibilities? You may have shorted something out while you were near the board. Have you tried SMC reset?
Yes, i was disconnected from power. No, i keep it out of reach of any liquids. I dont think so, when i do the SMC reset the fans turn on and everything but they are loud. When i restart the system with a shut down they wont turn on on the next power up.

None of them
Can you control the fans with software, such as smcFanControl ?
This is for troubleshooting, not as a work-around

It sounds like you did not compensate for the temperature sensor when you swapped out the spinner hard drive for an SSD. However, that should only have an effect on the hard drive fan. The CPU fan and the Optical drive fan should work in either case. Something else is going on if all three fans are not spinning up.
i figured it out. I installed a 3rd party fan control. I had to manually set the temperatures so the three fans could spin up. It was weird because it was set to auto and it would not do a thing.
Like I said above, that was because of the temperature sensor. But, it appears you have it working with the fan control app.
