We disable the motherboard's onboard CPU fan control and all CPU power management features. The CPU fan is fixed at 7V with an adaptor while the graphics card fan is locked at 70 percent speed using MSI Afterburner. The system is loaded using Prime95 25.11 and Unigine's Heaven 4.0 benchmark. We use Core Temp and GPU-Z to monitor the temperatures, taking the maximum values after 15 minutes - enough time for the readings to plateau.
