Linus Tech Tips - Remaking Our Most Hated Video
The video revisits a previous failed attempt to create a PC that keeps pizza warm using waste heat. The team aims to redeem the concept by directing the heat generated by the PC components into a chamber designed to maintain the pizza at a safe temperature of around 140°F. They use a tower PC on its side, with radiators and fans configured to direct hot air into the chamber. The team experiments with different materials and configurations, including using acrylic for the side panel to incorporate RGB lighting that indicates the chamber's temperature. Testing shows that the setup can maintain the pizza's warmth effectively, with the chamber holding a temperature of around 65°C, significantly better than the control pizza left at room temperature. The project demonstrates the potential for creative use of computer waste heat, though it acknowledges limitations in airflow and performance throttling under heavy load.
Key Points:
- The PC uses waste heat to keep pizza warm, targeting a temperature of 140°F for food safety.
- Acrylic panels with RGB lighting are used to indicate the chamber's temperature.
- The setup maintains pizza warmth effectively, with the chamber holding around 65°C.
- Airflow control is crucial to balance heat retention and component cooling.
- The project shows potential but faces challenges with performance throttling.

2. 🍕 Heating Strategy for PC Pizza
- The primary aim is to redirect waste heat into the pizza rather than releasing it into the air.
- Achieving and maintaining a target food safety temperature of 140° F is crucial.
- The strategy involves keeping the pizza at 140° F until it is consumed, ensuring it stays within Arms Reach for optimal consumption timing.
- Implementing precise temperature control mechanisms can help achieve these objectives effectively.

5. 🌡️ Temperature Testing and Adjustments
- Prime 95 and Furmark are employed for stress testing the CPU and GPU to ensure they operate without thermal throttling, monitored through Hardware Info.
- Initial readings indicate CPU at 60°C, GPU at 69°C, with an ambient temperature of 27°C, highlighting the need for adjustments to align with the target chamber temperature of 60°C.
- Adjustments involved altering airflow by restricting some intake fans, which raised the temperature from 32°C to 40°C quickly.
- Further adjustments include modifying fan settings to slower speeds and considering manual control via BIOS for improved thermal efficiency.
- The impact of these adjustments on performance stability and efficiency remains a key focus, ensuring optimal operation without compromising on performance.
6. 🔍 Evaluating the Results
- The chamber temperature was at 61°C, indicating an improvement from the previous day.
- The temperature of the control pizza dropped by 3°C per minute, while the chambered pizza's temperature decreased by only 1°C per minute.
- Both pizzas were initially placed in at 60°C, providing a consistent testing condition.
- The chamber maintained a temperature around 65°C, suggesting effective temperature retention.
- The slower cooling rate of the chambered pizza implies better heat retention, potentially enhancing product quality during storage.
- The consistent initial temperature of both pizzas ensures that the observed differences are attributable to the chamber's effectiveness.
7. 🍕 Final Taste Test and Future Improvements
- The pizza warming system maintained pizza quality effectively, keeping the pizza glistening after 35 minutes, indicating successful heat retention.
- The system ensures food safety by keeping pizzas within a safe temperature range of 4° to 60° C for up to 2 hours.
- Proper airflow management is critical, preventing temperature issues despite a CPU reaching 90° without thermal throttling.
- For future improvements, the implementation of automated louvers could optimize airflow based on CPU and GPU load, enhancing heat retention without compromising performance.
