How to Tell if CPU Cooler Is Working: A Guide

The CPU cooler is a crucial component of a computer system as it helps regulate the temperature of the CPU, preventing it from overheating. However, it can be challenging to determine whether the CPU cooler is functioning optimally. In this article, we will discuss how to tell if a CPU cooler is working and address some frequently asked questions related to this topic.

1. Check the fan: The most apparent sign of a functioning CPU cooler is the spinning fan. If the fan is not moving or is making unusual noises, it is likely a sign of a malfunctioning cooler.

2. Monitor CPU temperature: Using software like Core Temp or SpeedFan, monitor the CPU temperature. If the temperature consistently rises above the recommended threshold, it may indicate an issue with the CPU cooler.

3. Observe system performance: If your computer is experiencing frequent crashes, freezes, or slowdowns, it could be due to an overheating CPU. Insufficient cooling can cause the CPU to throttle down to prevent damage, affecting system performance.

4. Physical inspection: Visually inspect the CPU cooler for any signs of dust accumulation or loose connections. Dust can restrict airflow, leading to poor cooling performance.

5. Touch test: Carefully touch the CPU cooler while the system is running. It should feel warm but not excessively hot. If it is too hot to touch, it could indicate a problem with the cooler.

6. BIOS/UEFI settings: Check the BIOS/UEFI settings to ensure that the CPU fan control is enabled. Some motherboards have options to monitor fan speed and set temperature thresholds.

7. Listen for abnormal sounds: A working CPU cooler should produce a consistent and low humming sound. If you notice any clicking, grinding, or rattling noises, it could indicate a failing or damaged fan.


1. Can I use my computer without a CPU cooler?
No, it is not recommended to operate a computer without a CPU cooler. The CPU can quickly overheat, leading to permanent damage.

2. How often should I clean my CPU cooler?
It is advisable to clean the CPU cooler at least once every six months. However, the frequency may vary depending on the environment and dust accumulation.

3. What should I do if my CPU cooler is not working?
If your CPU cooler is not working, it is recommended to shut down your computer immediately to prevent any potential damage. Consult a professional technician to diagnose and resolve the issue.

4. Can a CPU cooler be repaired?
In most cases, CPU coolers cannot be repaired. If a cooler is malfunctioning, it is best to replace it with a new one.

5. Are liquid CPU coolers better than air coolers?
Liquid CPU coolers generally offer better cooling performance compared to air coolers. However, they can be more expensive and require more maintenance.

6. How can I improve CPU cooling?
You can improve CPU cooling by ensuring proper airflow in your computer case, using high-quality thermal paste, and investing in a more efficient CPU cooler if needed.

7. Can a CPU cooler be too powerful?
A CPU cooler can never be too powerful. However, it is essential to ensure that the cooler is compatible with your CPU socket and fits properly within your computer case.
