Run your Raspberry Pi 4 cooler with a new firmware @Raspberry_Pi #Thermal
It’s no secret that the Raspberry Pi 4 is faster than the Raspberry Pi 3 B+. Unfortunately, getting better performance out of this board requires a heatsink or a heatsink and fan to ensure the board won’t be thermally throttled.
Last week, the Raspberry Pi Foundation released a new firmware to the Via Labs USB Controller (VLI). This USB controller handles the two USB 3.0 ports on the Pi 4, and the updated firmware drops the overall temperature by 3 degrees C to 5 degrees C. The writeup on the Raspberry Pi website is a lengthy blog post describing how they stress test the CPU and GPU to determine the power draw of the Pi at idle and load.
To ensure your Pi 4 is running the latest firmware, open a terminal on your Raspberry Pi and enter:
sudo apt update sudo apt full-upgrade
Then, to restart your Pi, run:
sudo shutdown - r now

We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
