Controle a velocidade do ventilador no linux sem drivers nvidia

Question

Eu tenho configuração de quemu-kvm como este - IGP no host (linux) e Nvidia no guest (windows). Eu coloco os drivers nvidia na blacklist sob o linux (arch dist.).

Existe uma maneira de definir a velocidade do ventilador GPU no Linux (é muito barulhento) antes de eu executar o Windows (no ventilador do Windows trabalhando em silêncio).

Obrigado antecipadamente!

Answer 1

Sim, configurando a velocidade do ventilador da GPU de uma placa gráfica nvidia sob o Linux é possível, veja isto questão relacionada em askubuntu.com . Resumindo:

• Edite seu xorg.conf e adicione Option "Coolbits" "4" a Section "Screen" . Ou apenas execute nvidia-xconfig --cool-bits=4 , o que gerará um xorg.conf completamente novo e definirá essa opção para você. Isso permite configurações de controle de ventilador.
• Depois de reiniciar o X ou o seu computador, execute nvidia-settings . Você encontrará uma nova configuração de ventilador de GPU localizada em Configurações térmicas . Você também pode controlá-lo via linha de comando ativando primeiro essa configuração via nvidia-settings -a "[gpu:0]/GPUFanControlState=1" e, em seguida, impondo uma velocidade de ventilador específica por meio de nvidia-settings -a "[fan:0]/GPUTargetFanSpeed=65" (nesse caso, 65%).
