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. The FLIRC Raspberry Pi Zero Case is finally here - overly engineered, affordable and adorable The FLIRC Zero shares the same genetics as the original FLIRC. 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. 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 Flirc case has a narrow cutout in its base positioned so as to allow a ribbon cable from the GPIO pins to exit there, but I have found that the ends of the connector of a standard 40-pin ribbon cable, when it is plugged in to the GPIO pins, foul the mounting pillars for the top of the case, so you can't close the case. 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. 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. 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. Material: acrylic Weight (including one Raspberry Pi 4): 54 g Number of boards supported: up to 3 Cooling method: vertical alignment The Raspberry Pi 4 Stand is about as simple as a case could possibly be. 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.
