There are multiple reasons that cause your system to heat up and only proper working CPU fans can calm it down. CPU fans are designed to flow the heated air out of the system through exhaust vents so that the temperature is regulated.
Sometimes, the default speed set for the cooling fans is unable to lower the internal temperature of the system. This is exactly when you feel the need of increasing the CPU fan speed.
For this purpose, BIOS is the best approach but, in some cases, the BIOS fails to boost up the fan’s speed so you have to try other methods.
If the system isn’t treated on time and well, the overheating can also catch fire which is surely a huge consequence. Therefore, it is always better to have a Plan B and in this situation, your Plan B will be changing the CPU fan speed without BIOS.
But, are there actually any alternatives? Can you really change the fan speed without BIOS?
To your surprise, yes you can. Not only one but, there are multiple ways that allow you to increase the speed of your system’s CPU fans if they are unable to cool down the system on time.
We have discussed all the effective strategies in this article, make sure you don’t miss any information and read it out till the end.
What is BIOS?
BIOS, short for Basic Input/Output System is basically the most crucial startup system of a computer. As soon as a computer is powered on, the microprocessor utilizes this specific program in order to officially start the computer system.
The BIOS program is built into the core processor software and boots up a PC. It is typically integrated into the computer system in the form of a motherboard chip and acts as a catalyst for the entire computer’s functionality.
Most importantly, the BIOS program works as an intermediary between the hardware and operating systems. It also has the responsibility of managing the flow of sensitive data between the Operating System and the connected devices, for example, keyboard, mouse, hard drive, etc.
How to change CPU fan speed without BIOS – Two useful techniques
The two most effective techniques that allow you to change the speed of your CPU fans without using BIOS are discussed in detail below. Make sure you understand each technique carefully and pick the one that you find the most suitable and easily doable.
External Fan Controllers
A super-easy way to speed up your CPU fans is by using an external fan controller. As suggested by the name, these controllers offer a wide range of options to control the CPU fans of your system and perform efficiently.
Just like the manual fan control method, you can check the temperature of your CPU fans anytime you want. Additionally, these allow you to turn on or off the fans as well as increase or decrease their speed according to the requirement.
You will come across a massive variety of external fan controllers in the market but, there are certain things that you must consider while purchasing one. These include aesthetics, the flexibility of pin socket, channels, how many fans you can monitor at one time, and controls.
Once you have found the right external fan controller for your system, you can easily keep it calm and cool without using the BIOS.
Fan Control Software
Since the external fans allow you to choose the fan speeds manually, the fan control software will do it automatically. The software is capable of detecting the temperature of your system and set the CPU fan speed accordingly. Once the PC is cooled down, the fan speeds are automatically turned slow.
Following are some of the most widely used fan control software:
The most widely used software, SpeedFan is designed for Microsoft Windows users and is available on the Windows Store for free. It not only helps the users to change the CPU fan speed but also allows them to monitor the temperature of different components on the PC.
It is a great choice in case the BIO on your PC fails to work and you plan to opt for the automatic option to change the fan speed.
Now, to set up this software, you must carefully follow the guidelines since it could be a bit tricky for beginners.
- From the official SpeedFan website, download the software installer.
- Now install and launch the software.
- In order to change the fan speed, you must configure the settings first.
- So, select Configure and choose Advanced.
- Click on Chip and find PWMs.
- From here, select all the options you would like to have control of.
- Now, from the “Set to” dropdown, you will see two choices i.e., “Software-controlled” or “Manual.
- Choose your preferred one and press “Remember it” so that the settings are saved.
After this, from the main window, you will be able to see all of your selected PWMs and choose the one you want to configure from there. This will allow you to change the fan speeds by typing manually or toggling the buttons.
Note: What we discussed above were the manual settings. If you opt for the “Software-controlled” also known as automatic settings, the software will itself detect the higher temperature of the system and boost up the fan speeds. Furthermore, as soon as the system returns to the normal temperature, the fan speed is slowed down.
ZOTAC FireStorm Software
Up next is one of the user-friendliest software that can easily enhance the CPU fan speed without requiring BIOS. ZOTAC FireStorm Software regulates the VDC values and clock rates by utilizing the graphics card modification. With this, the system’s temperature and fan speed are revealed.
Note: This software can be used on Windows 7, 8, and 10 OS.
NoteBook FanControl Software
Having an easy-to-use interface, the NoteBook FanControl Software is highly functional and a great choice to increase the CPU fan speed. Its user interface is super convenient that even first-time users can easily use it without any issues.
From current fine speed measurements to the temperature of the CPU, it detects it all. In the program’s Main Menu, you will find a slider that is basically the fan controller. Once your computer is powered on, the software is enabled automatically.
Note: This software also has computability with Windows 7,8 and 10.
Argus Monitor Software
This software works silently in the background without requiring the BIOS and does the job perfectly. The Argus Monitor Software features a CPU NGP display that keeps an eye on the temperature.
The paid version of this software offers additional features of recording and monitoring the HDD temperature and even the health condition of your monitor. You can use the software for absolutely free for the first 30 days.
Note: The supported Operating Systems include Windows 7, 8, and 10.
EasyTune 5 Software
You can enhance your system’s management using this software as it offers fine-tuning for the system. The proficient management is done by using the memory timings as well as recorded voltages.
The EasyTune 5 Software is another amazing software that works without needing the BIOS. It is integrated with an overclocking mechanism that is used to enhance the overall performance of your computer.
Moreover, you can check the health of your monitor from time to time, thanks to the ultimate monitoring system of this software. Some other impressive features that this software is packed with include its ability to switch from one ward to another in an advanced way.
The best thing about this software is that it allows the users to configure the fan speeds of multiple CPUs at one time depending on the RMPs and their temperatures.
Note: This software can be used on all versions of Microsoft Windows OS.
A malfunctioning heat sensor or higher RMPs result in increased temperatures of a computer system that needs to be cooled down at the right time. The best way is however the BIOS program but, in the absence of BIOS, you can try out other alternatives too.
Many programs cause your processor to heat up that ultimately provoke the CPU fans to spin even faster. Higher the RPM, louder the noise and lower the RMP, more chances of the system to overheat.
When a CPU manages heavier tasks for a longer time, the system’s temperature starts rising which requires to be calmed. In case your BIOS doesn’t work on time, you can try out any of the two useful techniques mentioned in the article.
Whether you choose an external fan controller or a fan control software, make sure you make the correct choice. In this way, the job will be done with perfection without causing you additional pennies to get the system repaired.
