Cooling & Fan Control

Manage cooling profiles and fan settings for optimal performance and noise levels.

Overview​

Your EDC includes an active cooling system with intelligent fan control to keep components running at optimal temperatures:

Cooling System:

  • High-performance cooling fans located at the back of the compute drawer
  • Fans exhaust hot air directly out the rear panel
  • Intake from interior airflow through perforated materials
  • Temperature-based automatic speed control
  • Three user-selectable cooling profiles

Location: Fans are mounted at the back of the larger drawer shelf, facing the rear panel

Control: Manual profile selection via button on the fans in the top drawer

For Most Users: Leave on Balanced​

The EDC comes pre-configured with the "Balanced" cooling profile, which works well for most deployments.

Quick Check (30 seconds):​

  1. Listen to the Fan Noise:

    • Should be a steady, low hum during normal operation
    • Fans will speed up under heavy load
    • Should not be excessively loud or completely silent

  2. Feel the Exhaust Air:

    • Place hand near rear panel exhaust vents
    • Should feel warm air flowing out
    • Not hot enough to be uncomfortable

✅ Fans running normally? You're done!

Understanding Cooling Profiles​

The EDC offers three cooling profiles with different fan speed curves:

🌿 Eco Profile (Quietest)​

Best For:

  • Office environments where noise matters
  • Light workloads (basic VMs, low CPU usage)
  • Cooler ambient temperatures (< 20°C / 68°F)

Fan Behavior:

  • Starting speed: 2800 RPM at 25°C (77°F)
  • Maximum speed: 4000 RPM at 45°C (113°F)
  • Noise level: Very quiet, gentle hum
  • Cooling capacity: Adequate for light loads

When NOT to Use Eco:

  • High ambient temperatures (> 25°C / 77°F)
  • Heavy sustained workloads
  • All nodes running at high CPU utilization
  • Dense VM deployments

Best For:

  • Most deployments and use cases
  • Mixed workloads (some VMs, normal usage)
  • Normal ambient temperatures (15-25°C / 59-77°F)
  • Good balance of cooling and noise

Fan Behavior:

  • Starting speed: 3200 RPM at 25°C (77°F)
  • Maximum speed: 4600 RPM at 45°C (113°F)
  • Noise level: Moderate, noticeable but not loud
  • Cooling capacity: Good for typical edge workloads

This is the default profile - works well in most situations.

⚡ Turbo Profile (Maximum Cooling)​

Best For:

  • Hot environments (> 25°C / 77°F ambient)
  • Maximum compute workloads
  • High-density VM deployments
  • When you need maximum cooling capacity
  • Shorter deployments where noise isn't a concern

Fan Behavior:

  • Starting speed: 3600 RPM at 25°C (77°F)
  • Maximum speed: Maximum RPM at 40°C (104°F)
  • Noise level: Loud, datacenter-level noise
  • Cooling capacity: Maximum available

Trade-Off: Significantly louder but provides best thermal performance.

How to Change Cooling Profile​

Locate the Fan Control Button:​

  1. Unlock and Open the Top Storage Drawer

    • This is the larger, full-depth drawer

  2. Look at the Rear of Fans of the Drawer

    • Fan controls are visible from inside the shelf
    • Control switch is located on or near the fans

Change the Profile:​

  1. Move the switch toggle up or down to cycle through profiles.

  2. Close the drawer when done

Note: The selected profile is retained even after power cycling the EDC.

Airflow and Ventilation​

Keep Vents Clear​

Rear Panel Exhaust:

  • Keep at least 6 inches (15cm) clearance behind the EDC
  • Don't block exhaust vents with equipment or walls
  • Exhaust area should have open air circulation

Front Panel Intake:

  • Perforated materials allow air intake from front
  • Don't cover the front panel completely during operation
  • Optional mesh filter cloth may be available (check your edition)

Side Ventilation:

  • EDC case has ventilation holes and perforations
  • Don't stack items on top of closed EDC
  • Maintain clearance on sides if possible

Profile Recommendations:

  • Eco: Not recommended for most deployments
  • Balanced: Moderate workloads, controlled environment
  • Turbo: Recommended for most production deployments

Environmental Considerations​

🌡️ Operating Temperature Guidelines

Recommended Ambient Temperature Range:

  • Ideal: 15-25°C (59-77°F)
  • Acceptable: 10-30°C (50-86°F)
  • Not recommended: Below 5°C or above 45°C

Note: The EDC is designed for deployment in controlled environments, not exposed to extreme temperatures.

If Deploying in Hot Environments:

  • Use Turbo cooling profile
  • Ensure excellent ventilation
  • Consider reducing workload during peak heat
  • Monitor temperatures closely
  • Provide shade or climate control if possible

If Deploying in Cold Environments:

  • Allow EDC to warm up before heavy workloads
  • Condensation may occur when bringing cold EDC into warm environment
  • Let system acclimate for 30 minutes before powering on
🏜️ Dusty Environments

Current Configuration:

  • No user-serviceable air filters at this time
  • Airflow design uses perforated materials
  • Not recommended for extremely dusty environments

If Deploying in Dusty Conditions:

  • Use Balanced or Turbo profile (higher airflow helps prevent dust buildup)
  • Position EDC to minimize dust intake
  • Some editions may include optional mesh filter cloth for front intake
  • Monitor for dust accumulation over time
  • Contact your reseller/partner about filter options

Dust-Sensitive Deployments:

  • Construction sites: Use with caution, provide dust barriers
  • Desert/sandy areas: Minimize exposure, use enclosure if possible
  • Industrial environments: Assess dust levels before deployment

Troubleshooting​

🔧 Fans running very loud constantly

Problem: Fans at maximum speed all the time, very noisy

Possible Causes:

  1. Turbo Profile is Active

    • Check fan control button, switch to Balanced or Eco
    • May have been changed accidentally

  2. High Ambient Temperature

    • Check room/environment temperature
    • Is EDC in direct sunlight or hot area?
    • Provide better ventilation or cooler location

  3. Heavy Workload

    • Check what VMs/applications are running
    • High CPU usage will increase temperature
    • This is normal behavior - fans doing their job

  4. Blocked Airflow

    • Check rear panel exhaust - is it blocked?
    • Is EDC against a wall or in tight space?
    • Ensure 6+ inches clearance at rear

  5. Temperature Sensor Issue

    • If fans run at max speed even when system is cool
    • May indicate sensor problem
    • Contact your reseller/partner for support
🔧 Fans not running or very slow

Problem: Can't hear fans running, no air from exhaust

Solutions:

  1. Check Cooling Profile

    • May be on Eco with low system load
    • This is normal - fans run slower when cool
    • Try Balanced profile to hear fans clearly

  2. System is Very Cool

    • If ambient temperature is low and workload is light
    • Fans may run at minimum speed
    • This is normal and efficient

  3. Fan Failure

    • If no air at all from exhaust even under load
    • Temperature warnings in HCI platform
    • Power down system immediately
    • Contact your reseller/partner for service

  4. Fan Control Issue

    • Try cycling through profiles
🔧 Temperature warnings or thermal throttling

Problem: HCI platform showing high temperature warnings, performance degraded

Immediate Actions:

  1. Switch to Turbo Cooling Profile

    • Provides maximum cooling immediately
    • Should reduce temperatures within minutes

  2. Check Airflow Obstructions

    • Verify rear exhaust is completely clear
    • Remove any objects blocking vents
    • Ensure EDC has proper clearance

  3. Reduce Workload Temporarily

    • Shut down non-essential VMs
    • Reduce CPU-intensive processes
    • Let system cool down

  4. Improve Environment

    • Move EDC to cooler location if possible
    • Add external fan or air circulation
    • Reduce ambient temperature

Long-Term Solutions:

  1. Reassess Deployment Environment

    • May be too hot for sustained operation
    • Consider climate control
    • Evaluate workload distribution

  2. Check for Hardware Issues

    • Failed fan or sensor
    • Dust accumulation
    • Contact support if thermal issues persist

Best Practices​

For Quiet Operation:

  • Use Eco profile in office/quiet environments
  • Keep workloads moderate
  • Deploy in climate-controlled space
  • Maintain good ventilation

For Maximum Performance:

  • Use Balanced or Turbo profile
  • Ensure excellent ventilation
  • Monitor temperatures under load
  • Don't restrict airflow

For Long Equipment Life:

  • Avoid sustained operation at high temperatures (> 65°C)
  • Use appropriate cooling profile for your environment
  • Keep exhaust clear at all times
  • Respond to temperature warnings promptly
