Cooling Pad for 15,6" Gaming Laptop-Legion 5/Pro

Why i created this:

The cooling stand is designed exactly for the Lenovo Legion 5 15ARH05h. But it fits my new Legion 5 Pro 16IAX10 too. Unfortunately, I cannot say whether it will fit other gaming laptops.
Nevertheless, I would like to share this here.

I use the laptop to play games on a usb-c docking station, but you can also work/play on it like this.

I have tested various fans. These include Arctic F8, Arctic P8, BE QUIT! BL044.
Contrary to my assumptions, I achieved the best result with the Arctic F8.
I think you can achieve even better results with Noctua fans, but they are significantly more expensive.

As it is very warm in my apartment in summer, I wanted to support my laptop from the outside in addition to the internal cooling and I want to slow down the internal fans with LegionFanControl as they can get very loud.

During a test run (unfortunately not warm in the apartment), I got the result that the CPU dropped from 63.6°C to 57.2°C at a constant internal fan speed.
The GPU from 67.1°C to 61.9°C.
This difference increases as the temperature in the apartment rises. Unfortunately, I have not taken any pictures.

Printing Notes:

Resolution: 0.2
Filling: 20-30
Walls: 3
Material: PLA
Supports: only for the part with the PWM controller
Position: 

Position the part so that it lies flat on its side.
Please align/mirror the parts the way you want them.
Switch on the left or right side (also note the cable tie fixings).

Installation Instructions:

To assemble the laptop stand you will need the following parts:

4 x M5x10 mm screws 
4 x M5 nuts 
2 x 6 mm x 332 mm rods (I used an old gas pipe)
4 x M5x15 mm (or longer) like ISO 7380
2 x 80 mm fans 3-Pin, 12V (I used Arctic F8)

1 x PWM-Controller 12V 1803B 1803BK (build in switch)

1 x power supply 12v

cableties
cable

I cut an M5 thread into the gas pipes to screw the side parts on later.
Once all the printed parts have been assembled, the fans can be installed.
I decided to install them with a PWM controller to be able to regulate the speed.

After the fans were installed, I laid the cables to the pwm controller and connected them there.
I did the same with the power supply unit.
I soldered pins to the cables so that I could use the original fan plugs
In order to be able to lay the cables neatly, two versions are provided with options for cable ties

Note that I only realized that the PWM controller has a switch after I had finished printing.
You can find the model without the fixture for the switch as an STL file.

I used this PWM-Controller housing:

thanks too MangoFan

I would be happy about a make if you print it!
