After reading " When you need some coolness, " I remembered my long-standing idea, which I couldn’t reach.
The idea is commonplace, it has been in my head for a long time, but now the summer has come. And now, it's time to implement it.
For the manufacture we need:
The first thing to do is to find out what size the hole is - a window leaf or, perhaps, a chimney, ventilation. And only then go to the store and buy fans. In our century of globalization and standardization, just spit - stumble on window leaves of different sizes. In order not to be upset later, it is better to measure the window in advance, counting on the fact that in addition to the fans, the window should include a frame, which in the case of foam is better not to make very thin.
I decided to ask the price in advance and downloaded the price of the local store:
The choice fell on one of the cheapest, at the same time, dimensional fans. Naturally, an option with bearings. The trip to the store was successful and I began to prepare the fans for their destination.
Here I advise you not to buy cheap backlit fans. It may be beautiful, but in practice there is little light and sense from them. They rotate more slowly than brothers.
To begin with, it was necessary to deal with wires. There are two and a half approaches:
I am not a barbarian, but I don’t particularly strive for design elegance, so I chose the second option.
Check the fan. My fan was designed for 12 volts, just as much as I gave him.
After checking two fans on the table I did not want to do further :) It was already cool. But it was stupid to stop there, because there were two more coolers, and the air was fresh on the street.
The most improvised material was chosen for installation - a piece of polystyrene from a box from some household appliances.
It turned out to be slightly broken, it had to be glued.
As it turned out, this glue also dissolves polystyrene, so it bonded well, almost melted. The effect was similar to dichloroethane, which is convenient to use in the event of a plastic fracture.
Next, the fans must be interconnected. I wanted to combine them on elastic bands, but they were not found. I had to use tape. Also, you can fix the coolers with brackets in their mounting holes, you can screw them with screws in different places of the strip, in case it is not made of foam. There are many options - you choose. I used tape (later I just found a black elastic tape) and connected the fans in pairs, and then connected the two blocks into one.
Next, I marked the outline of the fan block on the foam strip with a disc marker and cut it out. Cutting is, of course, better than expected. You can trim it so that the fans can always enter, and if you go too far, they will fall out. They sat so tightly with me that I decided not to fix them with anything.
After what has been done, it remains only to remove the wires. I twisted the black and red wires into pigtails, and the yellow ones I put inside the frame so as not to interfere. There were also plugs inside, which can be, if necessary, returned to the wires and used coolers for their intended purpose.
We mount the fan in the window, connect to the power supply and enjoy the fresh air!
You can power this whole thing from the computer’s power supply or another power supply. In my case, it was a 15 volt Soviet power supply with a stabilizer.
It remains only to improve the device to taste:
Fresh air to you!
The idea is commonplace, it has been in my head for a long time, but now the summer has come. And now, it's time to implement it.
For the manufacture we need:
- Plank of any material, whether it is cardboard, polystyrene foam or duralumin sheet.
- 2-4 coolers to taste
- Fasteners
- Wires

To begin with, it was necessary to deal with wires. There are two and a half approaches:
- Barbaric. The wires are cut off, soldered in one heap. Further use of coolers for their intended purpose in the computer is difficult, at least you need to mount the plug back.
- Semi-barbarian. Necessary wires are neatly removed from the plugs (or everything is possible, but I left the plugs in place so as not to lose). Further use in the computer occurs without problems, you just need to return the wires to their places in the connector.
- Elegant. Four (or how many fans?) Connectors are installed on the frame, powered in parallel. They include coolers. The most time-consuming and requires the installation of connectors, the connectors themselves and soldering.

It remains only to improve the device to taste:
- Add window hardware
- To make your own converter for operation from a wall outlet, it is possible to build it into a frame
- Add switch
- Any other upgrade that comes to mind
Fresh air to you!
