DolphinRC Heatsink for DJI O4 Unit: The Ultimate Cooling Solution
The DJI O4 Air Unit is amazing for FPV flying. However, it has one big problem: overheating. Fortunately, the DolphinRC Heatsink solves this issue completely. This guide shows you exactly how this simple upgrade transforms your flying experience.
What Is the DJI O4 Air Unit and Why It Needs Cooling
The DJI O4 Air Unit is a powerful video transmission system. It sends crystal-clear 4K video from your drone to your goggles. Moreover, it uses advanced digital technology for the best picture quality.
Here’s what makes the O4 unit special:
- High-resolution video: Transmits up to 4K at 60fps
- Low latency: Only 28ms delay for racing
- Long range: Up to 13km transmission distance
- Smart features: Automatic channel switching and interference avoidance
However, all this power comes with a cost. The O4 unit draws significant power and generates lots of heat. In fact, it can consume up to 9 watts during peak operation. This high power consumption creates thermal challenges that affect performance.
The Problem: Overheating Issues in DJI O4 Units
Many pilots experience frustrating overheating problems with their DJI O4 units. These issues happen more often than you might think. Furthermore, they can ruin your flying session completely.
Common overheating scenarios include:
- Bench testing: Unit gets hot within minutes when powered on
- Hot weather flying: Summer temperatures make the problem worse
- Long-range flights: Extended high-power transmission creates excess heat
- Continuous recording: 4K video recording adds extra thermal load
When your O4 unit overheats, you’ll notice several warning signs. First, the video feed may start stuttering or dropping frames. Next, you might experience increased latency or connection issues. Finally, the system may shut down completely to protect itself.
| Condition | Time to Overheat | Flight Performance Impact |
|---|---|---|
| Indoors, 25°C | 4-6 minutes | Minor throttle |
| Outdoors, 35°C+ | Less than 3 minutes | Severe latency/shutdown |
| Continuous 4K feed | Around 5 minutes | Stutter/frame drop |

FAQs About Using Heatsinks with DJI O4
Pilots often have questions about adding aftermarket cooling to their DJI O4 units. Here are the most common questions and our detailed answers:
Will this void my DJI warranty?
The DolphinRC Heatsink doesn’t permanently modify your O4 unit. It uses thermal pads and friction fit mounting, so it’s completely reversible. Therefore, you can remove it if warranty service is needed.
Is active cooling better than passive cooling?
Active cooling (fans) can be more effective but adds weight, complexity, and noise. Our passive heatsink provides excellent cooling without these drawbacks. For most pilots, passive cooling is the better choice.
Will this affect my video signal quality?
No, our heatsink doesn’t interfere with RF signals or antennas. The aluminum construction actually provides some EMI shielding benefits. Many pilots report slightly cleaner video feeds after installation.
Can I use this with other DJI units?
This heatsink is specifically designed for the DJI O4 Air Unit. It won’t fit properly on other models like the O4 PRO，O3 or Vista. Check our product lineup for compatibility with other DJI units.
How do I clean the heatsink?
Simply wipe it with a dry cloth or use compressed air to remove dust. The aluminum construction is very durable and easy to maintain.
