How to make #DIY CPU air tunnel?
I needed air tunnel for my new Ryzen 3 2200G APU, so I was doing a little research some time ago. There was any cheap air tunnel on the EU market at this time. Because of that I made it myself. Do you wish to made it too?
What we need to prepare
- computer case with perforated side wall
- old or broken fan
- empty plastic bottle
- knife
- ruler
- glue like thing
If the computer case has not perforated side, please don’t make air tunnel. In this case use tower cooler combined with rear exhaust fan.
Let’s do it
- open the computer case
- measure distance between top of the CPU coolers fan and the side wall
- cut a piece of bottle in needed length
- carefully extract the motor with blades from old or broken fan
- insert the piece of bottle into fans frame and temporary fix it together (f.e. by paper towel)
- try to mount it and check if there is enough space between it and coolers fan (f.e. 5mm)
- if the end of bottle touches or is nearly to touch the coolers fan, shorten it
- stick it together by glue like thing (f.e. by glue)
- you did it
Don’t forget to check the position and length of the tunnel.
It works (in my case)
The package temperature decreased from 76°C max / 73°C stable load to 72°C max / 68°C stable load, which means less noise from cooler. The boost frequency increased from 3693MHz max / 3393MHz stable load to 3693MHz max / 3418MHz stable load, which means nothing. The main side effect of this cooling solution is reduction of temperature of whole system, not only the CPU temperature.
