![]() ![]() I've got to wonder how much these metal cases affect WiFi and Bluetooth performance? It is louder than the Noctua 40 x 10mm fans I have on other systems, but you can install Pimoroni's software to toggle the fan on and off as needed (Buster required). It's pretty quiet, but definitely not silent. It has an addressable switch and RGB LED which you could use for other things (default is manual fan control and temperature indicator). On the other hand, the Fan Shim is a pretty cool little gadget (pun intended). In the end the goal is to keep the Pi cool enough to maintain maximum performance and prevent heat damage, and temps below 80C do that, so does a few C difference here or there really matter? The Flirc makes no noise, does not require any additional power, and will not pull dust into your system (like a fan). However, if both solutions keep the Pi4 below the 80C throttling temperature, then I would prefer the Flirc. In my experience, a fan alone works better than a heatsink alone. I don't have a graph, but if I was a betting man, I'd put my money on the fan. Obviously 100% constant extended use isn't likely but it'd be nice to have a case which can comfortably manage that! I'm just not sure if one exists.I would really like to see graph of Flirc Case vs Fan Shim. I've not been able to test myself but seeing some benchmarks online I'd seen extended 100% cpu stress tests (when overclocked to 2.0ghz) see the Flirc case to throttle eventually which suggests the level of heat dissipation isn't enough to level out below 80c. I cannot try for myself as I have neither Flirc case, nor desire to overclock my Pi4b as its already more powerful than my requirements. Reports suggest the Flirc case with no fans can already achieve this. Then if the case had 2 low powered fans on the top running quiet.ĭoes such a case exist yet? I feel like this design would easily run at 100% in 2.0ghz for extended periods without any throttling. This would allow a thermal pad to be placed on each of the heatsink pillars for optimal heat transfer to the case itself. I'd love to see an all metal enclosure, like the Flirc case, with 3 heatsink pillars which is screwed fairly tight to the board. At the highest, it runs in the high 50s but normally in the 40s. ![]() Nicely made: The instructions are very clear: The fan can be run at 3volt and is almost silent. I consider this the best of the three cases. As this is tucked away behind my desk, aesthetics are not important and goes to show how additional thermal capacity, albeit crude, can help.ģ. I added ALDI hardware corner brackets ("ALDI Angle Set 4 piece" 2.99GBP) top and bottom, which although primitive and steel, brought the temp down into the high 40s, low 50s. ![]() I concluded that the case had insufficient thermal capacity (for my liking). My Pi ran up to 68deg and the case felt uncomfortably hot to the touch. It now runs below 60degC, but is a bit noisy and the fan isn't secured. It ran hot so I placed a small fan inside the case, using the existing ventilation holes. ![]() The official RPi4 case with a finned heat sink. Results of my non-scientific trial is as follows:ġ. I know that the 'experts' say don't worry, but as an Electronic Engineer, I am uncomfortable running CPUs continuously at some of the temperatures recorded in these threads. I'm most impressed with the Pi4, as a desktop replacement but am concerned over the heat issue. A most useful thread, thank you all, along with the mass of information at ![]()
