The summary is:
The video is about an experiment to cool a CPU and a phone with a vortex cooler, a device that uses compressed air to create hot and cold streams. The hosts explain how the vortex cooler works, or at least try to, and test its performance with different nozzles and settings. They find out that the vortex cooler is not very effective for their purposes, and that it is more suited for industrial applications where precise and isolated cooling is needed. They also mention their sponsor, Vessi footwear, and suggest another video where they failed to cool a computer with a car radiator.
Here are the key facts extracted from the text:
1. The text is a transcript of a video where Linus and Alex from Linus Tech Tips try to cool a CPU with a vortex cooler.
2. A vortex cooler is a device that uses compressed air to create hot and cold air streams from a single nozzle.
3. The vortex cooler can reach temperatures of 200°C for the hot air and -50°C for the cold air, depending on the pressure and the nozzle size.
4. The vortex cooler needs a silencer to reduce the noise and a solenoid to control the airflow.
5. The vortex cooler is not effective at cooling the CPU, even when blowing directly at the die, because it cannot dissipate enough heat.
6. The vortex cooler is more suitable for industrial applications, such as welding, gas tank cooling, or electronics cooling in isolated areas.
7. The video is sponsored by Vessi, a footwear company that makes waterproof shoes.
