I took out my fans to clean the dust recently. Put them back in and all was working fine. Then the next re-boot I get error code 0511 fans not working.
CPU Fan is constantly on full power from the moment I turn the device on
Temps ar 38-41degres. CPU is under less than 10% loads. CPU fan is on full power.
Tried Dell Power Manager and Quiet Mode but doesn't do anything.
All BIOS and drivers are up to date.
So I replaced the CPU fan with a new one. Still the same. CPU Fan is constantly on full power! Sounds like a jet engine take off.
