Bug Description

Current Behaviour: After putting Laptop into sleep mode (S0ix), cooling fans slow down but keep spinning for several minutes (tested: 6 minutes).

Expected Behaviour: After putting laptop into sleep mode, cooling fans get the system into a temperature range where fans can be turned off as quickly as possible (< 30s).

Changing the behaviour is a big improvement to QOL when working on-the-go. It reduces the time waiting around for the system to reach a state where it can be stored for transport.
