How To Increase CPU Fan Speed (Step-By-Step Laptop Guide)

Preventing your computer from overheating can be challenging, especially if you always play games or use heavy programs. Thankfully, computers and laptops have CPU fans installed to cool your system when they overheat.  

In addition, most modern laptops and computer mothers are equipped with pulse-width modulation controllers and are used to control the revolutions per minute (RPM) of the internal cooling fans.  

If your device often overheats, increasing your CPU fan speed can help. This is because it will increase internal airflow and allow your system to cool down. In this article, we will guide you through how to increase CPU fan speed and understand the normal range of CPU fan speeds.  

A CPU fan is a computer component that is responsible for dissipating heat produced by the processor. CPUs generate heat from the internal electrical energy, and the more power it uses, the warmer it gets. If the CPU overheats, it can make it inefficient and eventually melt, making it inoperable. The CPU fan works with the heat sink to prevent such matter.  

A heat sink is a metallic PC component that directly sits on the CPU, attracting the heat away from the processor to its cooler, aluminum, fin-like structure. The CPU fan is attached to the heat sink, pulling air through the fins. The fan then dissipates the heat drawn to the heat sink, indirectly cooling the CPU.

How Important Is A CPU Fan? 

Computers hardware operation produces heat, but too much heat can affect your system and slow down processes. This is where the CPU fan comes in. It protects your CPU from overheating, ensuring that it will run efficiently.  

The CPU fan is a vital component of your computer that keeps the CPU cool and workable. Because of excessive heat and pressure, the CPU tends to become very hot, and when this happens, the CPU fan cools it down and makes it capable of working correctly. It is attached to the inner part of your CPU and starts working as soon as the CPU starts.  


What Is The Normal Range Of CPU Fan Speeds? 

The normal range of CPU fan speeds mainly depends on the kind of PC cooling solution you have. For example, if you are using a stock CPU fan, the recommended speed range is at 70% of RPM or above.

However, for gamers and users who run heavy programs, the ideal fan speed is at 100% of RPM, especially when the CPU temperature reaches. But if the temperature is only around 50C to 55C, a typical fan speed should be around 50% RPM. 

If you want to manipulate your CPU fan speed more or under its ideal speed range, be very careful as its speed is a double-edged sword. Here’s what could happen if you try to run it beyond the normal range:  

CPU Fan Speed Runs at High RPM 

Running your fan at a higher RPM than the regular speed can help cool your CPU’s temperature, increase its lifespan, and open overclocking possibilities. However, it will make a loud noise and use more power from your device. Furthermore, it will require you to clean your fan frequently and reduces its lifespan.  

CPU Fan Speed Runs At Low RPM 

If you put your fan’s speed at a lower RPM, the fan will remain quiet and make no noise. While this could be tempting, especially if you need to concentrate and don’t want to get distracted, lowering the speed can be detrimental to your CPU. It will overheat and shorten its lifespan, and your system will be inefficient because of high temperatures.
