This project makes a cooling system that keeps my bed cooler at night. I’m doing this project because I get hot sometimes when I sleep. This project will help me not get hot and sweaty at night. This will benefit other people who get hot at night.

This is a seriously impressive engineering project you planned like a real designer, built a working prototype system, and collected multiple trials of data with graphs. Even though the cooler didn’t meet the requirement yet, you did the most important thing: you figured out why and suggested smart improvements. Keep going you’re very close to a strong next version!
Excellent work designing a system to solve a real-life problem, because I also get hot sometimes when I sleep. I understand you did not get the desired results. Still, your project clearly shows the engineering process, including defining requirements, building a prototype, testing multiple trials, analyzing the results, and explaining why the design did not work as expected and why improvements are needed.
