While passive, our testing of the FLIRC shows it is much more capable than the small aluminum passive heatsinks we've been used to putting on the Raspberry Pi boards. We will ensure our case is adjusted to fit the latest Raspberry Pi. ![]() The FLIRC meanwhile is a Raspberry Pi case for $13~15 USD that is made out of aluminum and act as a heatsink for the device to dissipate heat. WHAT IS THE FLIRC RASPBERRY PI CASE The perfect home for your new Raspberry Pi 4. It's quite simple and the 30mm fan delivers sufficient airflow over the SoC but does not employ any heatsink or allow any heatsink to be attached. This friction-fit header makes it very easy to install on the Raspberry Pi and if needing to remove later. The Fan SHIM is a ~$10 fan that connects to the GPIO pins on the Raspberry Pi for power and aligning it with the Broadcom SoC. The Raspberry Pi Foundation kindly sent over the Fan SHIM and FLIRC for our benchmarking at Phoronix. If you have data you care about, then 'sure' you need to worry about getting that off to a place you can restore from if you have a disk. The operating temperatures are in the 30-40 degrees Celsius range under heavy load, load that previously really skyrocketed the temperature without any. We've seen just how prone the Raspberry Pi 4 is to down-clocking and where as previous Raspberry Pi boards did fine with a small aluminum heatsink attached, for any serious work you will need a more capable cooler if you care about the performance. (6) - not if they're dataless compute engines. The design lets it sit neatly under a TV to power your media. ![]() This beautiful-looking case is made with aluminium, and acts as a heatsink. In this article we're looking at the Raspberry Pi 4 performance with a Fan SHIM as an active fan designed for running on the Raspberry Pi off the GPIO pins as well as the FLIRC as a metal case that passively cools the device. This sleek and simple case is the official case for Raspberry Pi, acting as a perfect enclosure at a low price. However, if you will be enduring the Raspberry Pi 4 with significant load for any measurable length of time, an active cooler is almost warranted or otherwise a very capable passive cooler. With the Raspberry Pi 4, a passive heatsink is an absolute minimum for running this new ARM SBC unless you want to deal with potentially drastic performance limitations based upon your operating conditions.
