3 good reasons to monitor your fans with PRTG

With Paessler PRTG as your fan monitoring tool, you can avoid fluctuations in voltage and overheating as it helps you control the speed and temperature of your fans. Plus, PRTG is an all-in-one network monitoring software that integrates monitoring of your fan with monitoring your entire IT infrastructure.

Icon Ventilation

More reliable IT systems

Properly working fans are crucial to your IT system’s reliability. Because if data cannot be retrieved from overheated servers and other network devices, this will certainly hamper business processes and productivity. PRTG helps you avoid costly downtime with easy fan health monitoring.

Icon Harddrive

Reduced hardware costs

You’ll save money with PRTG since you will not have to replace equipment as frequently. PRTG helps your hardware run smoothly by ensuring its surroundings are well-ventilated and free of excessive heat, since systems last longer when they stay cool.

Icon Boost

Optimal resource usage

PRTG helps you save on energy costs by ensuring your IT systems are energy-efficient. It keeps a 24/7 eye on temperature, power distribution units, and even air conditioners in your data centers and server rooms to help prevent systems from overheating.

What fan monitoring looks like in PRTG

Diagnose network issues by continuously tracking the availability, health, and performance of your fans. Show fan rotation per minute (RPM), the overall fan status, the number of failed fans, airflow, and other key metrics in real time. Visualize monitoring data in clear graphs and dashboards to identify problems more easily. Gain the overview you need to troubleshoot overheating fans and other fan failures.

PRODUCT OVERVIEW

“From a server perspective, we're monitoring all of the key components of our service such as CPU usage, RAM disk space, the Windows services that it's running, and network connectivity of that server. In terms of networks, we’re monitoring all of our switches, firewalls, and access points. It’s really useful to be able to easily pull performance metrics from the PRTG dashboard.”

Ollie Kerslake, Infrastructure Lead
Riverford Organic Farmers

“The tool has given us greater control over all types of devices connected to the network (switches, IP telephony, security cameras, IoT, WiFi) that previously remained opaque when dealing with service incidents. This has improved our ability to diagnose and resolve problems, which has translated into greater efficiency and a better user experience in both internal and public services.”

Jordi Tolosà Bel, New Technologies Technician
Vinaroz City Council

“Our objective was to be able to monitor the health of our most critical servers containing data and applications, but also the flows and bandwidth between headquarters, our 50 servers in the cloud and the 15 servers at our production sites. For us, it is essential to have a proactive approach to understand where the weaknesses of the IT system are to be able to improve them.”

Marc Boullier, CIO
Carambar & Co

Fan Monitoring: FAQ

 

How does a fan work?

The more heat that is generated by an IT system, the faster a fan must spin to dissipate the heat. Another observation: Fans get louder the faster they spin. A fan is powered by electricity. In a PC, the power supply is 12 volts. The power supply must be correct for the following reason: if the voltage drops, the fan will be less effective. When this happens, you can no longer ensure your laptop, server, or enclosure is being cooled or ventilated as needed. Consequently, the temperature of hardware components (motherboard, hard drives/HDD, SSDs, graphic cards, etc.) by vendors like Intel, AMD, Nvidia, and others can increase, and with it a risk of malfunctions and failures.

Why are fans vital to IT systems?

Like ventilators, fans swirl and circulate air. Fans perform three main tasks: cool, ventilate, and remove air from IT components. As a rule, all IT hardware comes equipped with a fan. For example, laptops and PCs have fans installed in their cases to keep CPU temperature and the temperature of their graphic and video card low. Servers and server racks  also need fans to function properly and not overheat.

What is a fan monitor?

A fan monitor is a system or device used to track the performance and status of cooling fans, typically in electronic equipment, server rooms, data centers, or industrial applications. Cooling fans are critical for maintaining optimal operating temperature ranges for equipment, and a fan monitor helps ensure they function correctly. Key aspects include:

  • Speed monitoring (RPM): Tracks the rotational speed of the fan in revolutions per minute (RPM) to ensure it operates within the desired range. Detects underperformance, which could indicate issues like wear, dust buildup, or mechanical failure.
  • Temperature monitoring: Some fan monitors like Paessler PRTG also track the temperature of the system or area being cooled to ensure fans are effectively maintaining the desired thermal conditions.
  • Operational status: Identifies whether the fan is on or off, including alerts for failures or malfunctions such as stalling or complete stoppage.
  • Alerts and notifications: Provides real-time alerts via sound, visual signals, or integrated management systems when the fan performance deviates from preset thresholds.
  • Power consumption tracking: In some advanced systems, monitors measure the power draw of the fan, helping assess efficiency and detect issues such as motor strain.
Why is monitoring fans in hardware important?

Why do IT systems, data storage devices, and server racks need to be ventilated in the first place? IT systems and servers always generate heat. However, when internal pieces become overheated, the performance of these systems and servers can drop considerably. In the worst case scenario, devices can crash or become damaged. For this reason, fans must be used to dissipate heat from servers, storage systems, computers, control units, switches, and other hardware components.

What is a sensor in PRTG?

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive. On average, you need about 5-10 sensors per device or one sensor per switch port.

We asked: would you recommend PRTG? Over 95% of our customers say yes!

Paessler conducted trials in over 600 IT departments worldwide to tune its network monitoring software closer to the needs of sysadmins. The result of the survey: over 95% of the participants would recommend PRTG – or already have.
