If designed in correctly, the FPs should not fail.

What has been discussed is that if you stall an FP at 12V it will fail very quickly. Stalling an FP at 6V should be OK for quite a while. Operation at high voltage and high torque (low speed) is problematic but you have an increased chance of failure the higher in voltage/torque you go.

At issue is that these are self cooling motors (you can see the fan in the end). If you put enough torque to slow the fan (motor) above 6V, you are at risk.
