💡 The Challenge: Not Just “Buying a Fan,” But Winning a Project
When one of our clients received a high-spec tender request for a thermal management system in a high-density storage cabinet, the requirements were far beyond a standard off-the-shelf fan.
The fan needed to follow a precise multi-stage temperature control logic:
- Below 35°C: Fan remains stopped (Standby Mode)
- At 35°C: Runs at 50% speed
- At 40°C: Runs at 70% speed
- At the maximum limit: Runs at 100% speed
- If stalled: Immediately triggers an alarm
This meant the fan had to include both intelligent control logic and built-in fault detection, not just mechanical performance.
The client needed a partner who could not only supply hardware but co-engineer a complete intelligent fan solution to help them win the bid.
🧠 Step 1: Deep Technical Analysis — Beyond the Specification Sheet
The client’s original design specified a sound alarm to indicate when a fan stalls.
However, through our professional experience in industrial cooling applications, MEGA engineers quickly identified a hidden problem:
Audible alarms are unreliable in high-noise environments.
- Industrial sites or data rooms often exceed 80–90 dB — making sound alarms hard to notice.
- Even if the alarm is heard, locating the exact fan or cabinet that failed takes valuable time.
This diagnostic delay can lead to equipment downtime or even system damage.
💡 Step 2: Visual Lock — Replacing Noise with LED + System Alerts
To solve this, MEGA proposed a smarter approach:
- Custom Stall Detection Logic: Embedded into the fan’s PCB, allowing instant detection of fan stall conditions.
- LED Visual Alert: When a fan stalls, its blue LED indicator lights up immediately. In large arrays, this allows instant identification of the faulty fan.
- System Synchronization: At the same time, the stall signal is sent to the main control system, triggering a digital alert in the client’s software interface.
✅ Result:
This “Visual + System Alert” dual feedback mechanism ensures instant localization of faults — far faster than any sound alarm could provide.
⚙️ Step 3: Precision Thermal Logic — Four-Level Temperature Control
To meet the tender’s performance criteria, MEGA designed and validated a custom 4-stage control curve, ensuring stable performance across temperature thresholds:
Temperature | Fan Speed | Function |
---|---|---|
<35°C | 0% | Standby / Energy Saving |
35°C | 50% | Low Power |
40°C | 70% | Load Boost |
≥Max | 100% | Full Protection |
This intelligent fan logic delivers high cooling efficiency with optimal power consumption, aligning perfectly with the client’s system-level energy-saving goals.
🎬 Step 4: Proof of Expertise — Real Project Demonstration
Before finalizing, we presented the client with a real test video from a previous project where MEGA successfully implemented a similar multi-level control and stall detection system.
This evidence gave the client full confidence that MEGA’s solution was tested, reliable, and production-ready.
🧩 Step 5: Full-Process Technical Support — From Power Scheme to Installation
Winning the tender was just the beginning. MEGA provided complete engineering documentation and support, including:
- Power Optimization Scheme: Showing how one power controller could efficiently supply four fan units, simplifying wiring and reducing system cost.
- Installation Drawings & Guides: Clear 2D installation diagrams and step-by-step assembly instructions ensured the client’s team could integrate MEGA fans perfectly.


This comprehensive technical support helped the client accelerate system integration, meet the tender’s deadlines, and ensure long-term reliability.
🤝 The Result: From Supplier to Technical Partner
In this project, MEGA FANS wasn’t just a supplier — we became the client’s cooling solution consultant.
Our end-to-end support — from design logic to testing and documentation — was a critical factor in helping the client win their high-spec tender.
If your next project requires custom fan control, unique thermal logic, or integrated monitoring capability —
stop compromising with generic fans.
