1. SolarWinds CPU Load Monitor EDITOR’S CHOICE

Tested on: Windows, Windows Server

SolarWinds Engineers Toolset CPU Gauges

The SolarWinds CPU Load Monitor is part of the Engineer’s Toolset, which is a bundle of more than 60 monitoring and entire system management utilities. The CPU Load Monitor can track the performance of network devices and watch to make sure their hardware doesn’t get overloaded. On testing the CPU Load Monitor we found the following key features.

Key Features:

  • Auto Discovery: Comes with an auto discovery feature that automatically detects new devices on the network.
  • Spots Capacity Issues: Identifies and alerts about CPU load capacity issues.
  • Live Reports: Provides real-time reports on CPU load status.
  • Alerts: Notifies users about critical CPU load conditions.

Why do we recommend it?

SolarWinds CPU Load Monitor isn’t designed for just one device, but it can monitor the CPU load on all devices on a network. The tool includes an autodiscovery service that sets up the parameters of the monitoring tool for each device.

Network devices rarely include mechanisms to measure temperature. So, there just isn’t a temperature metric to pick up from switches or routers. However, heat is usually only generated by these devices when they get overworked and the electronic elements that will create heat when overloaded are the CPU and the interfaces. The CPU Load Monitor measures these components and tracks their activity live in the Engineer’s Toolset’s dashboard.

SolarWinds Toolset CPU Monitoring

The CPU Load Monitor starts its service by searching the network for all connected devices and lists them in an inventory. Once that autodiscovery phase has been completed, each listed device will automatically be monitored and one of the tracked factors in the CPU load. The CPU load monitor also records interface statistics and memory utilization, so all of the elements inside a network device that could overheat are watched by the CPU Load Monitor.

The monitor automatically sets threshold levels on all of the performance statuses that it tracks. These can be adjusted manually. When a threshold is crossed, the CPU Load Monitor generates an alert. This alert is shown on the dashboard and is also sent out to key personnel as an email or SMS message. This facility means that technicians don’t have to sit watching the panel always for signs of overheating. The threshold levels should be set so that the warning gives staff enough time to take preventative measures before any physical damage or performance impairment occurs.

Who is it recommended for?

The CPU Load Monitor is most suitable for the administration of large networks. Although the managers of all sizes on networks need to watch over the CPU utilization of all routers and switches, that task becomes impossible to perform manually when you have many devices to watch.

During our testing, we identified the following pros and cons related to CPU Load Monitor.


  • Effective Alarms: Utilizes simple yet effective alarms for long-term proactive CPU temperature monitoring.
  • Effective Troubleshooting: Part of a larger tool specifically designed for network admins and IT technicians, offering additional troubleshooting tools.
  • Notification Channels: Alerts can be configured to email, SMS, or webhook, ensuring compatibility with various alerting platforms.


  • Trial Period Not Long Enough: Longer trial period desired to fully test all included features.

The Engineer’s Toolset, including the CPU Load Monitor, is available from SolarWinds on a 14-day free trial.


The CPU Load Monitor is our Editor’s choice because you can monitor multiple routers concurrently and set warnings and alarm thresholds with ease. It is part of the Engineer’s Toolset, a one-stop-shop for all network troubleshooting needs. One of the best options available today.

2. Paessler CPU Monitoring with PRTG (FREE TRIAL)

Tested on: Windows, Windows Server

Paessler CPU Load Monitoring sensor

Paessler PRTG is an all-in-one infrastructure monitor that covers networks, servers, and applications. When looking for a temperature monitor, there are several different systems that you could choose. The PRTG service is a bundle of sensors and every customer gets shipped the full set. When starting up the software, the systems device manager has to decide which sensors to turn on and so is able to tailor the system to adjust the necessary monitors.

We tested Paessler PRTG and found the following key features.

Key Features:


  • SNMP Manager: Manages devices using the Simple Network Management Protocol.
  • Reports on Device Conditions: Generates reports on the status and conditions of monitored devices.
  • Uses WMI: Utilizes Windows Management Instrumentation for monitoring Windows-based devices.
  • Live Device Load Tracking: Tracks the load on devices in real-time.

Why do we recommend it?

The Paessler PRTG CPU Monitoring tool will watch over the CPU utilization of all of the devices connected to your network, which includes endpoints, switches, and routers. A system of alerts means that you don’t even have to look at the console of the monitor in order to catch problems with CPU availability.

The PRTG package of sensors includes several monitors that can pick up temperature information either from servers or network devices. Temperature performance is one of the factors that can be reported through SNMP and PRTG has a sensor for that. However, not every hardware provider implements procedures to report on temperature by that method.

Paessler PRTG CPU Load Sensor

PRTG includes monitors that pick up CPU performance data on Windows servers through WMI. A sensor for Linux servers also monitors CPU performance managed by that operating system. PRTG has a total of nine different sensors that are capable of looking for temperature information gathered on servers and network devices. If none of your equipment has an actual thermometer inside, there is no way for any system monitor to collect temperature information. However, in those cases, monitoring CPU load on all devices acts as a proxy statistic for temperature statuses.

Who is it recommended for?

As with the SolarWinds tool, the PRTG CPU Monitoring service is a bidder help to the managers of large networks. However, the free tier of PRTG makes this assistance accessible to small businesses as well.


  • Scalability: Enables easy scalability of monitoring efforts within the PRTG ecosystem.

CPU Temperature Monitors FAQs

How do I see CPU temp on my desktop?

There isn’t a CPU temperature monitor in your operating system. In order to get information about CPU temperature, you would have to go down to the BIOS. It is much easier to install a monitoring tool. We recommend the SolarWinds CPU Load Monitor to check on heat-generating activities or the HWMonitor, which interprets BIOS data in a GUI interface.

Why is my CPU temperature 70 degrees on an idle laptop?

A CPU temperature of 70 oC/158 oF is normal when the computer is very active. However, when idle, the CPU’s temperature should be around 45 oC/113 oF. A high temperature implies that the CPU is not really idle, but has a heavy workload put on it by background tasks and services. If the CPU monitor shows that this is not the case, then the high temperature could be a sign of a broken fan.

How do I check my CPU usage?

In Windows, CPU usage is displayed as a live metric in the Task Manager.

  • Right-click on the Task Bar at the bottom of the screen and select Task Manager from the pop-up menu.
  • Wait for the Task Manager to open and then click con the Performance tab.
  • Click on CPU at the top of the left-hand options list to see a live graph of CPU performance.

How do I monitor my GPU temperature?

If you have a graphics processing unit in your computer, you can see its temperature in the Task Manager of Windows 10.

  • Right-click on the taskbar and click on Task Manager in the popup menu.
  • When the Task Manager opens, click on the Performance tab.
  • Scroll down the left-hand menu to find GPU. The mini display there includes the GPU temperature in Celsius.

What CPU temperature is too high?

There are many factors to be taken into account when working out what is an acceptable CPU temperature. However, as a rule of thumb, for an Intel processor, a temperature of more than 40 oC/104 oF when it is inactive is worrying. A temperature of more than 85 oC/185 oF when it is under full load is a cause for concern.

What is a normal CPU temperature at full load?

For Intel processors, generally, the normal CPU temperature at full load is between 50 and 60 degrees Celsius. Intel Celeron processors run hotter at about 65 to 80 degrees Celsius under full load. AMD processors don’t have as much variability per model as Intel processors. They shouldn’t go above 70 degrees Celsius under full load.

What do I do if I don't get a CPU temperature reading?

If you are using a temperature monitor and it doesn’t give you a reading, the chances are that the program you chose is not compatible with the status output mechanism of your CPU temperature gauge. Picking a different temperature monitoring package might solve the problem.

Can CPU temperature be wrong?

There are a number of factors in the chain of activity that goes into temperature reporting and if one of them is faulty, you will get an incorrect report, so CPU temperature monitoring can go wrong. To work out whether the temperature monitor is giving incorrect reports, look for illogical results. For example, if your CPU registers no activity and the fan is working properly but the monitor says that the temperature is high, the monitor is probably wrong.
