Monitoring with PowerShell: Monitoring system temperatures

This blog was requested by one of the partners I work with. At times, you want to monitor the device temperatures and fan settings; you don’t want a machine to be constantly making noise because it’s having a hard time cooling down. While I’m not really one of the engineers that firmly believes in a high impact of temperature on normal workstations I can understand the annoyance the extra noise brings.

To monitor this, we’re using WMI/CIM. Unfortunately, not all manufacturers publish this information to WMI. If the script fails with “Could not get CPU temperature. Your manufacturer might not support this.” Then this is the case. You’ll be able to use external tools to get the temperature then.

try {
    $t = Get-CimInstance MSAcpi_ThermalZoneTemperature -Namespace "root/wmi" -ErrorAction Stop | Where-Object -Property instancename -EQ "ACPI\ThermalZone\TZ01_0" | Select-object -first 1
    $currentTempKelvin = $t.CurrentTemperature / 10
    $currentTempCelsius = $currentTempKelvin - 273.15
    $currentTempCelsius.ToString() + "°C"
}
Catch {
    Write-Host "Could not get CPU temperature. Your manafacturer might not support this."
}

And that’s it! as always, Happy PowerShelling!

Automating with PowerShell: making stolen tokens useless with Global Secure Access

Last week I watched Merill Fernando talk to Alex Pavlovsky and Marilee Tuscak from the Entra team about something I’d kinda put under the “needs a GSA licence” branch and i’d check it out later, turns out that like most people, I half-assed the documentation and it turns out it doesn’t. There’s two features that come with any P1 license; Compliant network check and Source IP Restoration. So BP, P1, or even frontline worker licenses already have this.

CIPP ❤️ #IntuneForMSPs

We’re Joining #IntuneForMSPs 🎉

Being invited by Microsoft to join a global initiative is a big moment for us, and we want to be clear about why it matters. #IntuneForMSPs is Microsoft’s program to help MSPs deliver Microsoft 365, Intune, and Copilot services at scale, and CIPP is now part of it, bringing the largest MSP community in the channel directly to Microsoft.

The return of CyberDrain CTF

CyberDrain CTF returns! (and so do I!)

It’s been since september that I actually picked up a digital pen equivalent and wrote anything down. This was due to me being busy with life but also my side projects like CIPP. I’m trying to get back into the game of scripting and blogging about these scripts. There’s still so much to automate and so little time, right? ;)
