Mining Rig Fan Manufacturer
Stop Your Mining Rig from Overheating – Industrial-Grade Cooling Fans Built for 24/7 Operation
Every ASIC miner (Antminer, Whatsminer, Avalon) and GPU mining rig has one enemy: heat. When cooling fails, hash rates drop, hardware degrades, and downtime eats profits. LINKWELL’s high-static pressure, high-RPM DC fans are engineered specifically for crypto mining — up to 8000 RPM, dual ball bearings, 70,000+ hour lifespan.
Why Mining Rigs Need Specialized Fans (Not Standard PC Fans)
The 25mm vs 38mm Difference
Most standard PC case fans are 25mm thick — fine for occasional desktop use. But mining rigs run 24/7/365 at full load. The heat is relentless, and 25mm fans lack the static pressure to push air through dense ASIC heatsinks. Our 38mm thickness delivers a larger motor, deeper blades, and up to 5x higher static pressure.
| Feature | Standard 25mm Fan | LINKWELL 38mm Mining Fan |
|---|---|---|
| Thickness | 25mm | 38mm |
| Static Pressure | Low (~2–3 mmH₂O) | High (20–50+ mmH₂O) |
| Max RPM | 1500–2200 RPM | 4000–8000 RPM |
| Airflow (CFM) | 40–75 CFM | 150–300+ CFM |
| Bearing Type | Sleeve / Hydraulic | Dual Ball Bearing |
| Lifespan (24/7) | 6–12 months | 3–5+ years |

What My Clients Say
FAQ of Mining Rig Fan
Why do mining rigs overheat even with stock fans?
Stock fans on rigs like Antminer or Whatsminer are usually designed for standard ambient conditions (25°C, low dust).
In real environments—high temperature rooms, enclosed racks, or dusty workshops—these fans cannot generate enough static pressure to push air through dense heat sinks.
That’s why overheating happens even when the fans are “working normally.”
What makes an industrial 12038 fan better than standard 12025 fans?
The key difference is pressure + durability:
- Thicker design (38mm) → stronger airflow penetration
- Higher RPM (4000–8000) → better heat dissipation
- High static pressure (20–50+ mmH₂O) → effective through tight heat sinks
- Dual ball bearings → stable 24/7 operation
You’re not just moving air—you’re forcing heat out of the system efficiently.
How do I choose the right fan for my mining rig?
Focus on three factors:
- Cooling demand → High hash rate = high heat → choose 6000–8000 RPM models
- Power compatibility → 12V / 24V / 48V depending on your system
- Noise tolerance → Higher airflow = higher noise
For example:
- Medium load → 4000 RPM
- Heavy load / hot climate → 6000–8000 RPM
Will a higher CFM fan always improve cooling?
Not always. This is a common mistake.
In mining rigs, static pressure matters more than CFM because air must pass through dense aluminum heat sinks.
A fan with:
- High CFM but low pressure → air bypasses the heat source
- Moderate CFM + high pressure → actually removes heat
So the right question is not “How much air?” but “How strong is the airflow?”
Do I need waterproof or dustproof (IP-rated) fans?
If your environment includes:
- High humidity
- Dust-heavy air (mining farms, factories)
- Outdoor or semi-open installations
Then yes—IP55 / IP68 fans are highly recommended.
They prevent internal failure caused by dust accumulation or moisture corrosion.
