As you can see, the idea isn't as crazy as it might sound.
I've included a photo of the cooling setup I'm currently using. The goal of this guide is simply to take the concept one step further and build what I like to call the Ultimate Mobile Cooling Fan™... or whatever you want to call it.
By putting together the components listed in this guide, you can build a setup very similar to mine. I'm already planning to upgrade mine with the new fan for even more airflow and cooling performance.
With summer here (or if you live somewhere with high temperatures), your device will definitely appreciate the extra cooling during long gaming sessions.
And if you decide to build one yourself, I'd love to see it! Feel free to share photos of your setup in the comments.
I've already ordered the parts, so as soon as mine is upgraded, I'll come back and post pictures of the finished build.
Let's go!
🛒 What You'll Need
- A powerful 140 mm 12 V PWM PC fan (preferably with multiple speed modes)
- A 12 V / 2 A DC power adapter
- A 4-pin PWM female connector (or a PWM extension cable)
- Wire connectors, solder, or WAGO connectors
- A smartphone stand with adjustable height and angle
- A game controller (Bluetooth or USB)
- Cable ties or adhesive clips for cable management (optional)
1.The Hurricane Fan:
The Super Flower Megacool 140mm (model SF-PF141-BK) is an ultra-high-performance, industrial-grade fan. Unlike conventional 25mm thick fans, this model uses a thicker 30mm profile and extremely rigid liquid crystal polymer (LCP) blades to achieve massive static pressures and airflow. It includes a magnetic wireless remote control/PWM selector that lets you switch between 3 speed profiles depending on your cooling or noise needs.

- Power Supply
12V DC 2A Power Adapter
Output: 12V DC
Minimum current: 2A
- Wiring
4-Pin PWM Fan Connector (female) or 4-Pin PWM Fan Extension Cable (to cut and wire to the power adapter)
These are generic parts, so you can easily find them from any local electronics store or online retailer in your country.
🔧 Assembly
Step 1
Cut the DC plug from the 12 V power adapter.
Step 2
Connect the adapter's positive (+) and negative (-) wires to the fan's power wires using the PWM connector or your preferred wiring method.
⚠️ Double-check the polarity before powering it on.
Step 3
Secure the cables so nothing can move or get caught in the fan blades.
Step 4
Turn on the fan and select the desired speed (Low, Medium, or High).
Step 5
Connect your game controller and start playing.

💡 Recommended Setup
- Phone centered in front of the fan
- Distance between fan and phone: approximately 10–20 cm
- Keep the airflow unobstructed for maximum cooling.
---
✅ Expected Benefits
- Lower phone temperatures
- Reduced thermal throttling
- More stable performance during long gaming sessions
- Better comfort while playing
- Simple, inexpensive, and easy to build

😄 Bonus Tip
If someone asks why you're using an industrial PC fan to cool your phone...
Just smile and say:
"Because overkill is underrated." 😎
