In this video, I run a series of live tests to find out how different cooling fans perform on a Raspberry Pi 3.
I compare multiple fan models from small to large and test each one under stress. I also explore whether it's better to blow cool air into the case or extract hot air out.
Each test starts at the same temperature and is run for a fixed amount of time while logging CPU temperatures in real time. I use a custom script to monitor performance and generate a graph at the end for easy comparison.
Whether you're building your own Pi project or just want to keep your system cool, this test will help you make better fan choices.
