Keeping your gaming PC running smoothly is crucial for an optimal gaming experience, and a key player in this equation is your CPU fan. This humble yet essential component spins at varying speeds to ensure your processor stays cool during intense gaming sessions.
However, understanding how it works and finding the right fan RPM (Rotations Per Minute) for gaming can be a bit perplexing. Questions about monitoring and controlling CPU fan speeds, concerns over noisy fans, or the opposite issue of fans not running fast enough to cool the system are common among users.
In this article, we’ll explain what constitutes an ideal CPU fan RPM and explore recommended settings for gaming PCs. Whether you’re tweaking settings or just curious about keeping your system cool, this guide will help you navigate the world of CPU fans and find the sweet spot for your gaming setup.
Does Adjusting CPU Fan Speed Matters?
When it comes to the intricate balance of your PC’s performance, the question of adjusting your CPU fan speed often arises. However, it’s crucial to approach this matter with caution.
In most cases, tampering with fan settings is not advisable, as the default settings managed by the BIOS are designed to automatically synchronize with the CPU temperature. This is especially significant because constant monitoring of CPU temperature isn’t feasible during routine tasks or gaming.
While seeking a quieter computing experience, investing in a high-quality aftermarket CPU cooler is recommended, offering superior cooling performance without compromising on noise levels.
For those determined to tweak fan settings, adjusting BIOS configurations or utilizing specialized software can be an option, but it’s paramount to ensure that the fan speed consistently stays within normal limits to maintain system stability.
What is a Good Fan Speed (RPM) For Gaming?
The optimal CPU fan speed for your PC is determined by the fan size, RPM ranges, and the delicate balance between cooling efficiency and noise levels. Larger fans, with their ability to push the same amount of air at lower RPMs, often stand out for their quieter operation.
Typical CPU fan RPM ranges vary based on fan size, ranging from around 600 to 3000 RPM. However, the ideal CPU fan speed isn’t just about achieving maximum RPM. It’s a nuanced compromise between cooling performance and fan noise.
Here are typical CPU FAN RPM Ranges depending on the Fan Size of your CPU Cooler:
- 140mm Fans: ~400 – 1200 RPM
- 120mm Fans: ~500 – 1500 RPM
- 92mm Fans: ~600 – 2000 RPM
- 80mm Fans: ~800 – 2500 RPM
- 92mm Intel Laminar RM1 (Stock Cooler): ~600 – 3150 RPM
- 92mm AMD Wraith Prism (Stock Cooler): ~600 – 2800 RPM
Ideal CPU Fan Speed on The Basis of Fan Size & Temps
The ideal speed for your CPU fan is like finding a middle ground. If it spins faster, your computer stays cooler and works better, but then it can get noisier and wear out faster. However, doubling the fan speed doesn’t mean your computer gets twice as cool; it doesn’t work that way.
Think of it like a team effort. The fan is just one player. Other things like the radiator, thermal paste, air temperature around your computer, and more, all work together to keep your CPU cool. So, finding the right fan speed is about making sure everything works well together without making too much noise.
Ideal CPU FAN Speeds for different Fan Sizes:
- 140mm Fans: 600 – 800 RPM
- 120mm Fans: 750 – 1000 RPM
- 92mm Fans: 1000 – 1300 RPM
- 80mm Fans: 1250 – 1600 RPM
- 92mm Intel Laminar RM1 (Stock Cooler): 1575 – 2100 RPM
- 92mm AMD Wraith Prism (Stock Cooler): 140 – 1850 RPM
For instance, the best fan settings for gaming PCs should be:
- 0-40 degrees: 20% fan speed
- 40-55 degrees: 20% – 35% fan speed
- 55-70 degrees: 35% – 60% fan speed
- 70-100 degrees: 60% – 85% fan speed
How to Check Your Computer Fan Speed
Keeping an eye on your computer’s fan speed is crucial for ensuring your system stays cool and performs optimally. Here are two simple ways to check your PC fan speeds:
1. Check Your Fan Speeds in Your BIOS
To access your BIOS:
- Shut down and restart your computer.
- Depending on your computer model, use Del, Esc, F2, F10, F11, or F12 to access the BIOS menu.
- Look for fan control settings in the Hardware Monitor section of the BIOS.
- Here, you can view and adjust your fan RPM to ensure they are running at the desired speed.
2. Use Software to Check Your Fan Speeds
Alternatively, you can use free software like SpeedFan to check your fan speed. SpeedFan not only monitors fan speed but also reads other sensors on your motherboard, providing information on voltages, speeds, and temperatures from within your operating system.
- Download and install SpeedFan on your computer.
- Open the app, and click on the ‘Configure‘ button in the main window.
- Select the Fans tab and choose the CPU fan for detailed information.
- By following these simple steps, you can easily keep track of your computer’s fan speed and make adjustments to ensure optimal performance and temperature control.
CPU Fan RPM FAQs
Is 1000 – 1200 RPM a normal CPU fan speed?
The normal CPU fan speed can vary based on factors like the size of the fan and the cooling requirements of your system. While many CPU fans run at around 5000 RPM, a speed of 1000 to 1200 RPM might seem a bit low for some setups, particularly if you want your system to stay cool quickly.
Is 2000 RPM Good For CPU Fan?
To keep your computer at a good temperature, it’s a good idea to run your CPU fan at 2000 RPM. However, at this speed, the fan can be pretty loud. Not all fans have to go up to 2000 RPM, though. The size of the fan blades plays a role—if the blades are larger, the fan can move more air without needing to spin at 2000 RPM.
Is 5000 RPM Of CPU Fan Good?
The 5000 RPM CPU fan is the maximum range for any PC. Your CPU fan should only run at this high RPm if you are dealing with severe overheating.
Continuously running at this speed with damage the life span of the fan and its ball bearings.
Is 3000 RPM Too High For CPU?
It’s normal RPM for a CPU fan considering that you aren’t playing games or doing intensive work. Again the CPU fan speed and its RPM also depend on the size of the fan blades.
What Should Be the Best Fan Settings for Gaming PC?
If you are using a standard water cooler to cool down your CPU. Then the best CPU fan settings should be:
- Temp: 40°C speed: 50 RPM
- Temp: 50°C speed: 60 RPM
- Temp: 65°C speed: 70 RPM
- Temp: 70°C speed: 100 RPM
Although it’s quite rare in modern CPUs to reach 70° C you should always set 100% RPM.
How Many Fans Does a Gaming PC Need?
For an ideal gaming PC setup, having three case fans is recommended, and this includes a fan positioned on the GPU (Graphics Processing Unit). This setup is crucial for effectively managing heat and ensuring that all components stay cool during gaming sessions.
At the very least, a gaming PC should have two case fans for optimal cooling. One fan, called the exhaust fan, should be placed on the back panel to push hot air out of the PC. The other, an intake fan, should be positioned on the front panel to bring in fresh, cool air. This two-fan configuration helps maintain a balanced airflow, preventing the system from getting too hot.
Does Increasing Fan Speed Increase Performance or FPS?
Yes, when you increase your CPU fan speed RPM it will result in lower temperatures and you will get better performance as well. If you are experiencing stutter then you will also get slightly better FPS in CPU-demanding games.
