What Are Fan Curves and Why Do They Matter?

Understanding Fan Curves

A fan curve is a relationship between temperature and fan speed. It tells your fans:

• How fast to spin at each temperature
• When to speed up or slow down
• How aggressively to respond to heat

Example:

• At 40°C → Run at 30% speed (quiet)
• At 60°C → Run at 50% speed (moderate)
• At 80°C → Run at 80% speed (aggressive cooling)

Default vs Custom Fan Curves

Benefits of Custom Fan Curves

Better thermal management – Keep temps in your preferred range
Reduced noise – Fans only spin as fast as needed
Longer fan lifespan – Less wear from constant speed changes
Improved performance – Sustained boost clocks during gaming
Battery savings (laptops) – Lower fan speeds = less power draw

When to Use Custom Fan Curves

Create custom curves if:

• Default profiles are too loud during light tasks
• Laptop throttles during gaming (needs more cooling)
• You want silent operation for office work
• You overclock and need aggressive cooling
• You live in hot climate (need higher fan speeds)

Stick with defaults if:

• You’re satisfied with current performance
• You don’t notice fan noise
• You never thermal throttle

Prerequisites and Requirements

What You’ll Need

✅ Compatible Hardware:

• ASUS laptop with Armoury Crate (ROG, TUF, VivoBook Pro)
• OR ASUS desktop motherboard with fan headers
• At least 2 controllable fans (CPU and/or system fans)

✅ Software:

• Armoury Crate installed and updated
• Latest version: Download from ASUS Armoury Crate Download

✅ Knowledge:

• Your CPU and GPU safe temperature ranges
• Basic understanding of cooling needs

Check Fan Control Compatibility

Test if your fans are controllable:

1. Open Armoury Crate
2. Go to Device tab
3. Look for Fan Control or Fan Xpert section
4. You should see:
   • CPU fan
   • GPU fan (laptops)
   • Chassis fans (desktops)

If you don’t see fan controls:

• Update Armoury Crate to latest version
• Update BIOS to latest version
• Check ASUS support – older models may have limited support

Important Temperature Ranges

Know your safe temperature limits:

Your custom curve should keep temperatures in the “Safe Range” during normal use.

Step-by-Step: Creating Custom Fan Curves

Step 1: Access Fan Control Settings

1. Open Armoury Crate
   • Double-click desktop icon, or
   • Search “Armoury Crate” in Windows Start Menu
2. Navigate to Fan Settings
   • Click Device tab (left sidebar)
   • Scroll to Fan Control section
   • OR click Manual mode in Performance section
3. Select Manual Mode
   • Click dropdown showing current mode (Silent/Balanced/Performance)
   • Select Manual or Custom
   • Advanced interface appears

Step 2: Understand the Fan Curve Interface

You’ll see a graph with:

X-Axis (Horizontal): Temperature (°C)

• Usually ranges from 20°C to 100°C
• Represents CPU or GPU temperature

Y-Axis (Vertical): Fan Speed (%)

• Ranges from 0% to 100%
• 0% = Fan off, 100% = Maximum speed

Curve Line: The line connecting points

• Each point is a temperature/speed pair
• Line interpolates between points

Control Points: Circles you can drag

• Click and drag to adjust
• Add points by clicking on the line
• Remove points by right-clicking

Step 3: Create Your First Custom Curve

Example: Balanced Gaming Curve

We’ll create a curve that’s quiet at idle but ramps up for gaming.

Target behavior:

• Silent during web browsing (30-40°C)
• Moderate during light gaming (40-70°C)
• Aggressive during heavy gaming (70-85°C)

Point-by-point setup:

1. Clear existing points (if any):
   • Right-click each point → Delete
   • OR click Reset button
2. Add first point (Idle):
   • Click graph at 30°C, 30%
   • This sets: “At 30°C, run fans at 30% speed”
   • Creates baseline for idle operation
3. Add second point (Light Load):
   • Click at 50°C, 40%
   • Gradual increase for normal use
4. Add third point (Medium Load):
   • Click at 65°C, 55%
   • Balanced cooling/noise
5. Add fourth point (Heavy Load):
   • Click at 75°C, 70%
   • More aggressive cooling for gaming
6. Add fifth point (Maximum):
   • Click at 85°C, 90%
   • Emergency cooling if temps spike
   • Prevents thermal throttling

Your curve should look like a smooth increasing line from bottom-left to top-right.

Step 4: Adjust Hysteresis (Prevents Fan Fluctuation)

What is hysteresis?

• Delay before fan speed changes
• Prevents fans from constantly ramping up/down
• Reduces annoying fan noise fluctuations

How to set:

1. Look for Hysteresis slider (may be labeled “Response Time” or “Cooldown”)
2. Set to 3-5 seconds for most users
3. Higher values (5-10s) = smoother but slower response
4. Lower values (1-2s) = faster response but more fluctuations

Recommended settings:

• Desktop: 3-5 seconds (better airflow, can respond slower)
• Laptop: 2-4 seconds (limited airflow, needs faster response)
• Silent preference: 5-10 seconds (minimize speed changes)

Step 5: Configure Multiple Fan Profiles (If Available)

Some systems let you control multiple fans independently:

CPU Fan Curve:

• Tied to CPU temperature
• Directly cools processor
• Can be more aggressive

GPU Fan Curve (Laptops):

• Tied to GPU temperature
• Cools graphics card
• Important for gaming

System/Chassis Fans (Desktops):

• Tied to motherboard temperature
• Provides overall case cooling
• Usually gentler curve

How to configure separately:

1. In Fan Control section, look for tabs or dropdown:
   • “CPU Fan”
   • “GPU Fan”
   • “System Fan 1, 2, 3”
2. Click each tab
3. Create curve specific to that fan’s purpose:
   • CPU fan: Aggressive curve (handles high heat loads)
   • GPU fan: Gaming-optimized (ramps up at 60-70°C)
   • System fans: Gentle curve (provides baseline airflow)

Pro tip: Keep system fans at constant 30-40% for positive air pressure (helps dust management).

Step 6: Test Your Fan Curve

Always test before saving!

1. Click “Apply” or “Test” (don’t save yet)
2. Run stress test:
   • For CPU: Download Cinebench R23
     • Run multi-core test for 10 minutes
     • Watch CPU temps and fan speeds
   • For GPU: Download FurMark
     • Run burn test for 5 minutes
     • Monitor GPU temps
3. Monitor in real-time:
   • Keep Armoury Crate open
   • Watch temperature graph
   • Listen to fan noise
   • Check if temps stay in safe range
4. Evaluate results:
   • Temps below 85°C under load = Good
   • Fans audible but not screaming = Good
   • Temps above 90°C = Curve needs to be more aggressive
   • Fans at 100% constantly = Curve too aggressive (or cooling issue)

Adjustment tips:

• Too hot? Lower temperature thresholds (shift curve left)
• Too loud? Lower fan speeds (shift curve down)
• Fluctuating? Increase hysteresis
• Throttling? Add aggressive high-temp point (85°C → 100%)

Step 7: Save Your Custom Curve

Once satisfied with testing:

1. Name your profile:
   • Click Profile dropdown
   • Select Save As New Profile
   • Name it descriptively:
     • “Silent Office Work”
     • “Balanced Gaming”
     • “Maximum Cooling”
     • “Summer Mode”
2. Apply profile:
   • Click Apply
   • Curve is now active
3. Set as default (optional):
   • Settings → Performance
   • Select your custom profile as default
   • Will apply on startup

You can create multiple profiles for different scenarios!

Advanced Tips and Optimization

Tip 1: Seasonal Adjustments

Summer/Hot Climate:

• Shift entire curve 5-10°C left (more aggressive)
• Example: 60°C → 55% becomes 55°C → 55%
• Compensates for higher ambient temperature

Winter/Cold Climate:

• Can use more relaxed curve
• Ambient cooling helps, fans can run slower

Tip 2: Different Curves for Different Components

CPU-intensive tasks (rendering, compiling):

• Aggressive CPU fan curve
• Gentle GPU fan curve

GPU-intensive tasks (gaming, 3D work):

• Aggressive GPU fan curve
• Moderate CPU fan curve

Tip 3: Noise vs Cooling Optimization

Find your sweet spot:

Test fan noise at different speeds:

1. Set fan to fixed 30%, listen
2. Increase to 40%, note noise increase
3. Continue to 100%

Most fans:

• 30-50%: Quiet
• 50-70%: Moderate (noticeable but acceptable)
• 70-85%: Loud (for gaming/heavy tasks)
• 85-100%: Very loud (avoid unless necessary)

Goal: Stay in 30-70% range for normal use.

Tip 4: Monitor Long-Term

After setting custom curves:

1. Use HWiNFO64 to log temperatures over days
2. Review maximum temps reached
3. Adjust if seeing sustained high temps (80°C+)

Troubleshooting Common Issues

Problem: Fans Not Responding to Curve

Solution:

1. Restart Armoury Crate services:
   • Press Win + R → services.msc
   • Restart “Armoury Crate Service”
2. Ensure “Manual” mode selected (not Balanced/Performance)
3. Update BIOS (fan control via BIOS, software just interfaces)

Problem: Curve Resets After Restart

Solution:

• Save curve as a named profile
• Set profile as default in Settings
• Check if Windows Fast Startup is interfering:
  • Control Panel → Power Options → Choose what power buttons do
  • Disable “Turn on fast startup”

Problem: Fans Too Loud Even on Low Curve

Possible causes:

• Dust buildup (clean fans and heatsinks)
• Failing fan bearings (consider replacement)
• Inadequate cooling (repaste CPU/GPU)
• Background processes causing unnecessary heat

Problem: Thermal Throttling Despite Custom Curve

Solution: Curve can’t fix hardware cooling issues:

1. Repaste CPU/GPU with quality thermal paste
2. Ensure proper ventilation (laptop elevation, case airflow)
3. Check if heatsink properly mounted
4. Consider undervolting CPU/GPU for lower temps

Problem: Can’t Add More Than 4-5 Points

This is normal. Armoury Crate limits curve points. Work with what you have:

• Focus on critical temperature ranges (40-80°C)
• Use points where behavior changes (idle → load)

FAQ

Conclusion

Custom fan curves give you precise control over cooling and noise, and the 15 minutes spent setting them up pays off with better gaming thermals, quieter everyday use, longer hardware lifespan, and improved performance by reducing throttling.

A simple action plan works best: today, start with the Balanced Daily preset as your baseline. This week, monitor temperatures during normal use. Next week, fine-tune the curve based on how much noise you’re comfortable with. Ongoing, adjust the curve seasonally or after any hardware changes.

Remember to start conservative and increase fan speeds only if needed, watch temperatures for a few days before locking in changes, save multiple profiles for different scenarios, and keep your fans clean because even the best fan curve can’t compensate for dust buildup.
