在我的计算机中，我试图获取 CPU 温度。在 StackOverflow 上搜索我发现了这个：
C:\WINDOWS\system32>wmic /namespace:\\root\wmi PATH MSAcpi_ThermalZoneTemperature get CurrentTemperature
但我收到此错误：
Node - ADMIN
ERROR:
Description = Not supported
您可以使用此代码：
function Get-Temperature {
$t = Get-WmiObject MSAcpi_ThermalZoneTemperature -Namespace "root/wmi"
$returntemp = @()
foreach ($temp in $t.CurrentTemperature)
{
$currentTempKelvin = $temp / 10
$currentTempCelsius = $currentTempKelvin - 273.15
$currentTempFahrenheit = (9/5) * $currentTempCelsius + 32
$returntemp += $currentTempCelsius.ToString() + " C : " + $currentTempFahrenheit.ToString() + " F : " + $currentTempKelvin + "K"
}
return $returntemp
}
Get-Temperature
您可以使用 Open Hardware Monitor，它是一个开源软件 (MPL v2)。 您可以在此处访问命令行版本：

以管理员身份在命令提示符中运行以下命令：
wmic /namespace:\\root\wmi PATH MSAcpi_ThermalZoneTemperature get CurrentTemperature这会给你一些像这样的输出：
CurrentTemperature 3000 3010但请确保您以 管理员
身份运行 cmd在我的笔记本电脑上，上述所有结果都给了我错误的结果。只有这个以摄氏度显示 CPU 温度：
$data = Get-WMIObject -Query "SELECT * FROM Win32_PerfFormattedData_Counters_ThermalZoneInformation" -Namespace "root/CIMV2"
@($data)[0].HighPrecisionTemperature
我猜，每个 CPU 版本可能有不同的位置/公式来获取正确的 CPU 温度。
使用新的传感器，或者使用我拥有的传感器和高度。 它还显示临界温度和百分比（以摄氏度为单位） 它留下了一个文件Temperatures.txt以方便调试，以及带有来自传感器的序列化对象的xml

获取 CPU 温度的最稳定、最可靠的方法是使用 LibreHardwareMonitor 项目（其取代 OpenHardwareMonitor）中的 DLL。
这是 Powershell 中的代码片段：
# script to get the current CPU temperature, needs to run as admin/system
# requires an external DLL from the GitHub-Project "LibreHardwareMonitor"
# on first execution the script downloads the DLL from the gitHub-Project
# [email protected]
#Requires -RunAsAdministrator
cls
$dll = "$env:windir\system32\LibreHardwareMonitorLib.dll"
$storeDll = $true
if (!(Test-Path $dll)) {
$web = [System.Net.WebClient]::new()
# download the package:
$url = "https://github.com/LibreHardwareMonitor/LibreHardwareMonitor/releases/download/v0.9.2/LibreHardwareMonitor-net472.zip"
$zip = $web.DownloadData($url)
# extract the dll:
Add-Type -AssemblyName System.IO.Compression
$stream = [System.IO.Memorystream]::new()
$stream.Write($zip,0,$zip.Length)
$archive = [System.IO.Compression.ZipArchive]::new($stream)
$entry = $archive.GetEntry('LibreHardwareMonitorLib.dll')
$bytes = [byte[]]::new($entry.Length)
[void]$entry.Open().Read($bytes, 0, $bytes.Length)
# check MD5:
$md5 = [Security.Cryptography.MD5CryptoServiceProvider]::new().ComputeHash($bytes)
$hash = [string]::Concat($md5.foreach{$_.ToString("x2")})
if ($hash -ne 'd4a02aa7bd43a5c5ffd3d673bb20b54d') {break}
# save the dll:
if ($storeDll) {
[System.IO.File]::WriteAllBytes($dll, $bytes)
Unblock-File -LiteralPath $dll
}
} else {
$bytes = [System.IO.File]::ReadAllBytes($dll)
if (!$storeDll) {Remove-Item $dll -Force}
}
Add-Type -LiteralPath $dll
$monitor = [LibreHardwareMonitor.Hardware.Computer]::new()
$monitor.IsCPUEnabled = $true
$monitor.Open()
foreach ($sensor in $monitor.Hardware.Sensors) {
if ($sensor.SensorType -eq 'Temperature' -and $sensor.Name -eq 'CPU Package'){
$temp = $sensor.Value
break
}
}
$monitor.Close()
write-host "CPU-Package Temperature = $temp°C" -f y
根据这个问题的答案：
这可以解释为什么本页上的一些答案会返回温度，但它与实际的 CPU 温度有很大不同。要获得 CPU（和每个核心）的准确温度，您需要编写 内核驱动程序， 更复杂的事情。
CurrentTemperature 返回某个热区的温度，即主板上的某个地方。
