![]() ![]() Thanks for confirming this! I ordered one myself but it hasn't arrived yet. There are multiple cables on the linked page, which differ mainly in how their connectors are oriented, but they all have the same narrow connectors. I got a reply from Flirc which reassured me that these cables really do fit, so I bought one, and it does. I have left a message about this on the Flirc site, and will post their response in due course. I am not really inclined to buy a cable 'on spec' without more reason to think it really is different. seem to stick out as much as) those on the cables I have, and the specs do not include connector width. The connectors on all the ones which have images look like (i.e. I now see the FAQ entry, but the link points to a page with a table with multiple cables listed. I haven't tried it myself, if you do please let us know if it fits. There's a FAQ on the Flirc RPi 4 case page where question 9 specifically adresses the gpio ribbon cable issue: I haven't seen anything like this available. For a connector to work with the Flirc case, I think that it would need to be moulded on to the wire, with little or no overlap at the ends. Almost any 'filing down' will damage or destroy these clips, and the connector will then come apart and lose contact with the cable wires with minimal disturbance. The connectors I used then, and the ones that seem to have been used on the commercial ribbon cables I have now, come in two parts which are clamped together over the cable and held together by clips on both ends of the connector. I used to make my own ribbon hookups for IDE drives, since this allowed me to use the exact length of cable that fitted best for a given case/motherboard/drive location combination - improving both access and cooling. You'll probably need to file it down to 52mm in order to have the cable fit to narrowest top part of the pillars, but this is not recommended as it will surely weaken the connector. Well checking again the ribbon pin1-to-pin40 distance is about 51mm (again you may correct me on this) It may be a "stupid idea" but have you tried filing the sides of the ribbon connectors to reduce the overall length? In my measurement, the 40-pin ribbon connector's length is about 55.5mm (correct me on this), while the pillar to pillar widest distance is 53mm so definitely a 40-pin ribbon connector's 55.5mm will not fit. 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.I confirm this on the RPi3B+ version of the FLIRC case (just took mine from storage to verify pfletch101's concern) 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 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. 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. I had done testing and saw that even with a heat sink and a small fan, the Pi would still throttle after enough time at 100 CPU usage. 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. Definitive Raspberry Pi 4 with Flirc results: never throttles I got my Flirc case for my Raspberry Pi 4 today.
