NVIDIA GPU 风扇速度配置仅适用于 2 个 GPU 中的 1 个

Question 1

我最近也在为这个问题而苦恼。在做任何事情之前，请备份当前的xorg.conf。接下来，运行以下命令：

sudo nvidia-xconfig --enable-all-gpus --cool-bits=28

如果您需要AllowEmptyInitialConfiguration，True请运行以下命令：

sudo nvidia-xconfig --enable-all-gpus --cool-bits=28 --allow-empty-initial-configuration

保存并重启。这样你就可以控制任何 GPU 风扇了。如果你在启动时编写了此脚本，你的新命令将如下所示：

nvidia-settings --verbose=all -a [gpu:0]/GPUFanControlState=1 -a [fan:0]/GPUTargetFanSpeed=80 -a [gpu:1]/GPUFanControlState=1 -a [fan:1]/GPUTargetFanSpeed=80

Question 2

以下是 Python 代码：

import time
from pynvml import *

nvmlInit()

class Device:
  def __init__(self, index):
    self.index = index
    self.handle = nvmlDeviceGetHandleByIndex(index)
    self.name = nvmlDeviceGetName(self.handle)
    self.fan_count = nvmlDeviceGetNumFans(self.handle)

  def set_fan_speed(self, percentage):
    """ WARNING: This function changes the fan control policy to manual. It means that YOU have to monitor the temperature and adjust the fan speed accordingly. If you set the fan speed too low you can burn your GPU! Use nvmlDeviceSetDefaultFanSpeed_v2 to restore default control policy.
    """
    for i in range(self.fan_count):
      nvmlDeviceSetFanSpeed_v2(self.handle, i, percentage)
 
print(f"Driver Version: {nvmlSystemGetDriverVersion()}")
device_count = nvmlDeviceGetCount()
devices = [Device(i) for i in range(device_count)]

for device in devices:
  device.set_fan_speed(80)

try:
  while True:
    time.sleep(1)
except:
  # reset to auto fan control
  for device in devices:
    for i in range(device.fan_count):
      nvmlDeviceSetDefaultFanSpeed_v2(device.handle, i)
  nvmlShutdown()

请注意，在脚本退出时我们如何恢复到默认风扇控制。

这也是我的要点用于根据温度变化更新风扇速度。
