All RPM indicators showing zeroes and fans are maxed out

Post by book »

I just recently upgraded my iMac (OS 10.12.7) to Macs Fan Control v1.4.8 and after restarting from a few days being shutdown, the system's fans are all maxed out.  Macs Fan Control is showing all zeroes for the RPMs and only displays one sensor for my hard drive.  How do I reset this or fix it?
