ASRock Fan Control: How to Fix Loud PC Fans (August 2026)

Nothing tests your patience quite like a PC that sounds like a wind tunnel while you are trying to work. If you built or bought a system with an ASRock motherboard, you already have the tools to silence those loud fans built right into the board. ASRock fan control is built into every modern ASRock motherboard, and getting it configured properly takes just a few minutes once you know where to look.

This guide walks through every method available for controlling fan speeds on ASRock boards. Whether you prefer working inside the BIOS or want a Windows-based utility, the options below cover everything from basic preset modes to fully custom fan curves that respond to exact temperature targets.

Before jumping into the details, here is a quick summary of the three main approaches covered in this article.

Quick Reference: Three Ways to Control ASRock Fans

• BIOS/UEFI (H/W Monitor) – Press DEL or F2 during boot, then F6 for Advanced mode. Navigate to the H/W Monitor tab to access fan modes, custom curves, and FAN-Tastic Tuning. Settings persist without any background software.
• A-Tuning Software – Download from the ASRock APP Shop or the support page for your specific motherboard model. Provides a graphical fan curve editor inside Windows. Requires the app running in the background for settings to apply.
• Third-Party Software – Free tools like Fan Control by Rem0o and Open Hardware Monitor offer advanced features including mixed-sensor fan curves and GPU-temperature-responsive case fans. Works with ASRock boards alongside or instead of A-Tuning.

If you want permanent settings that survive reboots without any software, use the BIOS method. If you prefer a visual interface and do not mind a background process, A-Tuning or a third-party tool will serve you well.

Understanding ASRock Fan Control Basics

ASRock motherboards provide fan speed management through dedicated headers on the board itself. Each header connects to a fan and can independently adjust speed based on temperature readings. The board reads temperature data from sensors on the CPU and across the motherboard, then adjusts fan voltage or PWM signals to match your configured profile.

Your ASRock board can manage several fan categories. CPU fan headers control the cooler sitting on top of your processor. Chassis fan headers connect to intake and exhaust case fans. Some boards also include dedicated headers for liquid cooling pumps and auxiliary system fans. For help with physical fan connections, see our guide on connecting RGB fans to the motherboard, which covers header types and wiring.

Modern ASRock boards support both 3-pin DC fans and 4-pin PWM fans. The 4-pin PWM fans deliver finer speed control because they use a dedicated digital signal line rather than voltage adjustment alone. If your case fans are still 3-pin, DC mode works fine, but upgrading to 4-pin PWM fans unlocks the most precise ASRock fan control experience.

How to Access Fan Settings in BIOS/UEFI

The BIOS is the most reliable place to configure ASRock fan control. Changes you make here are stored on the motherboard itself, so they apply immediately at boot without requiring any operating system or background application.

BIOS Key Shortcut Cheat Sheet

• DEL or F2 – Enter BIOS/UEFI at startup
• F6 – Switch from EZ Mode to Advanced Mode
• F10 – Save changes and exit BIOS
• F9 – Load optimized defaults (useful for resetting)

These shortcuts are consistent across ASRock motherboard models, as confirmed by community discussions on the official ASRock forum and Reddit threads. If fast boot is enabled in Windows, you may need to restart from within Windows settings rather than using a cold boot to access BIOS.

Step-by-Step: Reaching Fan Settings

1. Restart or power on your computer.
2. Press the DEL or F2 key repeatedly as soon as the ASRock logo appears on screen.
3. Once inside BIOS, press F6 to enter Advanced Mode if you see the simplified EZ Mode layout.
4. Navigate to the H/W Monitor tab using the arrow keys or mouse.
5. Locate fan settings listed as “CPU Fan 1 Setting,” “Chassis Fan 1 Setting,” and similar labels for each header.

Each fan header has its own independent control. You can run your CPU fan on an aggressive curve while keeping case fans nearly silent, or configure every fan identically. The H/W Monitor tab also displays real-time temperature and fan speed readings, which is helpful for verifying that your changes are working.

Using A-Tuning Software for Fan Control

A-Tuning is the official ASRock utility for adjusting fan speeds from within Windows. It provides a graphical interface where you can drag points on a fan curve rather than typing values into BIOS menus. The tradeoff is that A-Tuning must remain running in the background for your settings to stay active.

One important note: A-Tuning is model-specific. The version for an ASRock B550M board will not work on a Z790 board. This is a common frustration reported on the ASRock forum and Reddit communities. Always download the version matched to your exact motherboard model.

Downloading A-Tuning Through ASRock APP Shop

ASRock bundles A-Tuning inside the APP Shop application, which acts as a central hub for all ASRock system utilities. Here is how to get it installed.

1. Open a browser and go to asrock.com.
2. Navigate to your specific motherboard model page using the search bar or product category listings.
3. Click the Support tab, then select Download.
4. Choose your operating system from the dropdown menu.
5. Download the ASRock APP Shop utility first (this is the launcher that manages all other ASRock software).
6. Install APP Shop, then launch it and find A-Tuning (sometimes labeled “Motherboard Utility”) in the available tools list.
7. Click install within APP Shop and follow the on-screen prompts.

If you prefer a direct download without APP Shop, you can find A-Tuning listed individually on the same motherboard support page. Some older motherboards may label the software as “F-Stream Tuning” instead of A-Tuning, but the fan control features are functionally identical.

Adjusting Fans in A-Tuning

1. Open A-Tuning from your Start menu or system tray.
2. Click the FAN-Tastic Tuning tab.
3. Select the fan header you want to configure from the dropdown menu at the top.
4. Choose a temperature source (CPU temperature or motherboard temperature) for that fan to respond to.
5. Drag the control points on the graph to set your preferred fan speed at various temperature levels.
6. Click Apply to activate the curve immediately.

Keep in mind that A-Tuning software settings override BIOS fan settings while the application is running. If you close A-Tuning or it fails to start with Windows, the board reverts to whatever was last saved in BIOS. For this reason, many experienced users configure their primary curves in BIOS and only use A-Tuning for temporary testing.

Mastering FAN-Tastic Tuning

FAN-Tastic Tuning is an ASRock-exclusive feature that automatically calibrates each connected fan. It runs a brief test sequence that ramps every fan from its minimum to maximum speed, measures the actual RPM range, and then builds an optimized curve based on those real measurements.

You can access FAN-Tastic Tuning in two places. Inside BIOS, look for the “Fan Tuning” option within the H/W Monitor tab. Inside A-Tuning, it occupies its own dedicated tab with the same name. Both versions perform the same calibration routine.

Running FAN-Tastic Tuning from BIOS

1. Enter BIOS using DEL or F2, then press F6 for Advanced Mode.
2. Go to the H/W Monitor tab.
3. Select the Fan Tuning option.
4. Confirm the prompt to begin the automatic fan calibration process.
5. Wait while the system tests each fan (this typically takes 30 to 60 seconds).
6. Review the generated curves and click OK to accept them.
7. Press F10 to save and exit.

The auto-generated curves usually strike a reasonable balance between noise and cooling. However, if you find the results too aggressive or too passive, you can always switch the fan mode from the auto-generated “Customize” setting back to Silent, Standard, or Performance, and then fine-tune from there.

Custom Fan Curves: Step-by-Step Guide

Building a custom fan curve is where ASRock fan control becomes genuinely powerful. A custom curve maps specific fan speeds to specific temperature thresholds, giving you exact control over how your system reacts to heat. This approach is ideal for gamers, content creators, and anyone who wants their PC to stay quiet during light tasks but ramp up cooling under heavy load.

Setting Up a Custom Curve in BIOS

1. Enter BIOS and switch to Advanced Mode with F6.
2. Open the H/W Monitor tab.
3. Select the fan header you want to customize.
4. Change the mode from Silent, Standard, or Performance to Customize.
5. A temperature-vs-speed graph will appear with several adjustable points.
6. Set each point to your desired temperature and corresponding fan speed percentage.
7. Verify that each successive point has a higher fan speed than the previous one (curves must be progressive).
8. Press F10 to save your configuration and exit.

Recommended Starting Curve

If you are not sure where to begin, the following curve works well as a starting point for most CPU coolers on ASRock motherboards.

• 40 degrees C and below – 20 to 30% fan speed (near-silent operation)
• 50 degrees C – 40 to 50% fan speed (gentle ramp up)
• 60 degrees C – 60 to 70% fan speed (noticeable airflow, moderate noise)
• 70 degrees C – 80 to 90% fan speed (active cooling under load)
• 80 degrees C and above – 100% fan speed (maximum cooling capacity)

This curve keeps your system quiet at idle and during light tasks, then progressively increases cooling as temperatures climb. Adjust each point up or down based on how loud your specific fans are and how hot your CPU runs under load.

PWM vs DC Control: What is the Difference?

One of the most common questions about ASRock fan control is whether to use PWM or DC mode for a given fan. The correct choice depends entirely on the physical connector on your fan. Selecting the wrong mode can cause fans to run at full speed regardless of your curve settings, or produce clicking and buzzing noises at low speeds.

Side-by-Side Comparison

• Connector – PWM uses 4 pins; DC uses 3 pins
• Speed Control Method – PWM uses rapid on/off digital pulses; DC adjusts voltage between roughly 7V and 12V
• Precision – PWM provides granular speed control across the full range; DC has a narrower effective adjustment range
• Low-Speed Behavior – PWM fans can run very slowly and quietly; DC fans may stall or click at very low voltages
• Compatibility – PWM requires both a 4-pin fan and a 4-pin header; DC works on any header with a 3-pin fan
• Typical Use – PWM for CPU coolers and quality case fans; DC for older or budget case fans

In the BIOS H/W Monitor tab, look for the “Control Mode” or “Fan Mode” setting under each fan header. You can choose PWM, DC, or Auto. The Auto option attempts to detect the fan type automatically, but it does not always get it right. If your fan behaves erratically on Auto, manually set it to PWM for a 4-pin fan or DC for a 3-pin fan.

Silent, Standard, and Performance Modes Explained

ASRock includes three preset fan modes for users who want a quick solution without building custom curves. Each mode applies a preconfigured curve that changes the balance between acoustic noise and thermal performance.

Silent Mode

• Prioritizes low noise above all else.
• Fans spin at reduced speeds across the entire temperature range.
• Component temperatures will run higher compared to other modes.
• Best suited for office PCs and media center builds where noise matters more than peak performance.
• Not recommended for gaming or sustained heavy workloads.

Standard Mode

• Strikes a middle ground between noise and cooling.
• The default setting on most ASRock motherboards out of the box.
• Works well for general computing, web browsing, and light gaming.
• A safe starting point before experimenting with custom curves.

Performance Mode

• Maximizes cooling capacity with less regard for noise.
• Fans run at higher speeds at every temperature point.
• Keeps CPU and system temperatures as low as possible.
• Best for competitive gaming, rendering, and overclocking scenarios.
• Expect noticeably louder fan noise even at idle temperatures.

To switch between modes, enter BIOS, navigate to the H/W Monitor tab, select the fan header, and choose Silent, Standard, or Performance from the list. Most users find that Standard mode is a comfortable daily setting, while gamers switch to Performance or a custom curve when they need maximum cooling. Users with other motherboard brands can compare fan control approaches across ASUS, MSI, and Gigabyte boards to see how ASRock stacks up.

Third-Party Fan Control Software for ASRock Boards

While A-Tuning handles basic fan control well enough, many ASRock users turn to third-party software for more flexibility. Community discussions on Reddit and the official ASRock forum frequently recommend external tools because A-Tuning is model-specific and lacks some advanced features. Here are the most popular options that work with ASRock motherboards.

Fan Control by Rem0o

Fan Control is a free, open-source Windows application that has become the go-to recommendation in PC building communities. It reads temperature data from your CPU, GPU, and motherboard sensors, then applies custom curves to any fan connected to your ASRock board. Unlike A-Tuning, Fan Control can make case fans respond to GPU temperature, which is incredibly useful when your graphics card heats up during gaming but your CPU stays relatively cool.

The interface supports mixing multiple temperature sources into a single curve, setting fan hysteresis to prevent rapid speed fluctuations, and creating custom fan profiles you can toggle with keyboard shortcuts. It runs on any Windows system and works with all ASRock motherboards regardless of model.

Open Hardware Monitor

Open Hardware Monitor is another free tool that reads temperature, fan speed, and voltage data from your ASRock motherboard. While its primary purpose is monitoring rather than control, it can adjust fan speeds on some boards by changing the reported fan control values. It is a lightweight option if you mainly need temperature monitoring with basic fan speed readouts.

Users on the ASRock forum have noted that Open Hardware Monitor is especially handy for verifying that BIOS fan settings are working correctly, since it displays real-time sensor data in a simple tree-view layout without requiring BIOS restarts to check readings.

HWiNFO64

HWiNFO64 provides the most detailed hardware monitoring available for ASRock boards. While it does not directly control fan speeds, it reports every sensor on your motherboard, including individual fan header RPM readings, voltage rails, and per-core CPU temperatures. Many users run HWiNFO64 alongside Fan Control by Rem0o to get comprehensive monitoring with full fan management.

Troubleshooting Common ASRock Fan Control Issues

Even with proper configuration, ASRock fan control can occasionally behave unexpectedly. The following solutions address the most frequently reported problems from community forums and support threads.

Fans Running at Full Speed Constantly

• Verify that fan control is enabled in the H/W Monitor section of BIOS, not disabled.
• Check whether you accidentally selected Performance mode, which keeps speeds high.
• Confirm the fan is plugged into the correct header and seated fully.
• Try loading BIOS defaults with F9 and reconfiguring your fan settings from scratch.
• Ensure the control mode matches your fan type (PWM for 4-pin, DC for 3-pin).

Fans Not Spinning

• Check the physical fan connection to the motherboard header.
• Make sure the fan is not set to “Off” or “Disable” in BIOS.
• Test the fan on a different header to rule out a dead header or dead fan.
• Some fans have a minimum startup voltage and will not spin at very low DC percentages. Increase the minimum speed percentage.

Settings Not Saving After Reboot

• Always press F10 to save and confirm before exiting BIOS.
• Check if A-Tuning is overriding your BIOS settings at Windows startup. Disable A-Tuning from launching with Windows to test.
• Clear CMOS by removing the motherboard battery for several minutes, then reconfigure your fan settings.
• Update your motherboard BIOS to the latest version, as older firmware sometimes fails to retain fan curves.

Fans Too Loud After FAN-Tastic Tuning

• Switch back to Standard mode as a baseline and see if noise improves.
• Manually lower the maximum fan speed in your custom curve to a comfortable ceiling.
• Adjust temperature thresholds upward so fans do not ramp aggressively at moderate temperatures.
• Check for dust buildup on fan blades and heatsink fins, which can force fans to work harder.

A-Tuning Not Detecting Fans

• Ensure you downloaded the correct A-Tuning version for your exact motherboard model.
• Run A-Tuning as administrator to give it access to hardware sensors.
• Check that fans are connected to motherboard headers, not directly to the power supply.
• If detection problems persist, use BIOS control instead or switch to Fan Control by Rem0o.
