Your Lenovo y530 CPU fan has stopped working, but the GPU fan is still running. You've already changed the thermal paste and disassembled the fans to check for issues, but you couldn't find the problem until you got a replacement. Regarding your question, yes, you can set a thermal limit for your CPU using software, even if the BIOS options are limited.
