Free CPU Temp Monitor

Monitor Your CPU with PRTG Network Monitor


High server CPU loads result in applications or files hosted on that server having very long response times. This reduces productivity and increases the risk of network failures.

Monitoring CPU helps you to keep control of the loads that your servers and workstations have to withstand. If you know how high the loads are, you can distribute them more evenly, and increase network speed and performance.

Why is CPU Monitoring Important?

In order to get a complete overview of a network and the loads that it is subject to, it is important to monitor parameters such as CPU and RAM load, disk usage, network traffic, and more. These factors help you to determine long time usage trends, prevent server overloads, and even to detect malware activity.

Using a free CPU monitor such as PRTG Network Monitor is therefore indispensable for efficient network management and troubleshooting.

Can I Monitor CPU Temperatures Using PRTG Network Monitor?

PRTG Network Monitor is Paessler's powerful network and CPU temp monitor program. It checks the status and performance of network components, measures bandwidth usage, and alerts you if anything in your network requires your attention.

The free CPU temperature monitor software can monitor disk space, CPU loads, memory, routers, servers, etc.

PRTG free CPU monitor can monitor CPU temperature, but it all depends on your hardware. For example, if your motherboard provides CPU temperature information via SNMP, you can set up a sensor to monitor temperatures.
