Selection Guide: How to Choose
Step 1: Calculate Required Airflow
Formula:
Required CFM = (Heat Load in Watts) / (ΔT × 3.17)
Where: - Heat Load = Total power dissipation (W) - ΔT = Allowable temperature rise (°C) - 3.17 = Conversion factor
Example: For a 500W GPU with 15°C temperature rise:
Required CFM = 500 / (15 × 3.17) = 10.5 CFM per GPU
Step 2: Consider Static Pressure Requirements
| Application | Required Static Pressure |
|---|---|
| Open chassis | 5-10 Pa |
| Dense heat sink | 20-50 Pa |
| Filter systems | 30-60 Pa |
| Long duct runs | 40-80 Pa |
Step 3: Bearing Type Selection
| Bearing Type | Lifespan | Noise | Cost | Best For |
|---|---|---|---|---|
| Sleeve | 20,000-30,000 hrs | Very Quiet | $ | Budget systems, intermittent use |
| Hydraulic (HY) | 30,000-50,000 hrs | Ultra-Quiet | $$ | Office environments, NAS |
| Dual Ball | 50,000-70,000 hrs | Quiet | $$$ | 24/7 operation, servers |
Real-World Deployment: AI Server Example
Scenario: 8-GPU AI Training Server
Configuration: - 8× GPU (500W each) = 4000W - 2× CPU (300W each) = 600W - Total Heat Load: 4600W
Cooling Solution: - Primary exhaust: 4× 12025 fans (90 CFM each) = 360 CFM total - GPU direct cooling: 16× 6025 fans (26.9 CFM each) - Intake: 2× 12025 fans with filters
Result: - Maintains GPU temperature < 75°C under full load - System PUE: 1.15 (excellent efficiency) - Noise level: 52 dB-A at 1 meter
