Hi,
As of today with the latest Blokas software, RPi4 B and Pimoroni Fan Shim, are there any know compatibility issues? I recall reading about a problem in the past but cannot find if it has been resolved.
Thanks,
Harry
With a new RPI 4 and newest pisound and fan shim it does not work. Pisound is detected but it failed to start jack. If I remove the fan shim pisound is working again. Thus I cannot even test if the fan shim service is leading to audio problems. Maybe it’s a power problem? Some (power) pins are used by both devices? I’m using the standard power supply. But I have no clue…
I’m running the latest version of the patchbox OS with a RPi4 B and have the pimoroni fan shim. The fan can be physically installed but it has several conflicts which to my knowledge have not been fixed. Both the fan shim and Pisound button interact with each other and cause issues. Also the auto-run script for the fan breaks Jack and I have yet to find the source of the issue.
-Hope this helps
Thanks fro the feedback. I had seen this at the Pimoroni site “Because Fan SHIM uses pin BCM18 to control the fan, and this pin is also used by I2S audio devices, you won’t be able to use I2S DACs like pHAT DAC, pHAT BEAT, and the IQAudio boards at the same time as Fan SHIM” and thought there might be an issue. I’ll try heat sinks first and if there is a heat problem I’ll bypass BCM18 and hardwire the fan ON and not use the fan software.
Sounds like a plan, I’m new to the raspbery pi so if you have success making the fan work with the pisound please post about it or reply to my comment 
it would be very apreciated.
I use rpi4 2gb ram version with pimoroni fan shim. It works pretty good, cooling down rpi, Im just not using auto-scripts to control fan ratio. Without it, in the pisound case, rpi got warm pretty fast, so ive chosen that way.

So in that case, the I²S pin used by the fan hat can be used for Pisound?
I didnt check audio, but midi works, pisound is available, jack starts. I can use puredata and patchbox and they looks like working fine.

Audio works. When the pimoroni fan-shim service is enabled something blocks audio or jack. Going into X the digital audio still works, just the jack based one is dead. When the pimoroni service is disabled, analog audio returns. Running the first use wizard gives the output that jackd cannot be restarted while the pimoroni service is enabled. I am still new to this, can’t really analyze, but I am pretty disappointed at this finding as the fan is quite loud, and I would like to see it switched off if the pi isn’t too warm… I bought the pimoroni pimoroni fan because someone recommended it in this forum - that was a misguided reco…
Actually the service can be enabled, it must just not be started. Here someone investigated - not with respect to pisound, but generally, about the systemintrusiveness of the “smart” fan:
Same thing with vanilla RpiOS (just the pisound hardware, no patchbox stuff). When the pimoroni service is running pisound and jack are dead.
Yes, the fan uses the same pins for controlling its speed that must be used for audio data transfer, so both functions can’t work at the same time.

FWIW, I just installed the pimoroni fan shim in my raspberry pi and am also using the Pisound interface. I also have the acrylic case from Blokas as well. From a physical perspective one of the standouts cannot be installed. I tried and it would be too high compared to the other 3 to put the case back together. It also threatened to bend the corner of the fan shim board. So I just used the other 3 and it seems to be fine. I did not install the software to control the fan. In my case it’s just always on and have had no problems with interference with Pisound. Some photos attached for reference.

Heya, since my pi4 got really hot within the acrylic case and i had some fanshims around I tried this out, too. Without installing any fanshim software it seems to work without issues, always running at top speed. Top speed is pretty loud though – is there a way to change the speed without running the fanshim software, or is it possible to install the fanshim software, have it throttle to a lower speed and disable before jack starts?
Have any of you experienced the fan to be “too” loud and find some workaround?
best,
dormir
Mine is not loud at all, very quiet.
thanks for sharing your insights, getting one of this fans today since Im hitting 80ÂşC almost with high audio processing

(In 2023) I just installed the Pumoroni fan shim on my Pi 4 4GB. I also have PiSound and the PiSound case. That is not going well. The back of the Pisound audio I/O rest on the fan and prevent it from spinning. With patient tweaking of screws and bolts and moving of connectors I can suspend the Pisound just barely above the fan, but then I can’t put the case together (defeating the purpose of getting the fan. I have not installed the fan shim service.
I would love other options for cooling that work with the RPi4, PiSound, and PiSound Case.
My most recent use of this combo is for Zynthian “stable-2211”. Without the fan and case, Zynthian launches fine and i can select and use Pisound as the audio interface. However, with the pisound case - it gets too hot and the thermometer displays regularly.
I loved the idea of PiSound, but I don’t use exposed electronics in my setups and need a case…if you have another no-solder option (e.g. a specific fan or pad) that allows me to use the PiSound case AND manage heat better, I would really appreciate it! The ideal outcome for me is getting to use Zynthian without the thermometer/heat warning and related throttling.
In my experience I could not install the standoff on the corner of the pi where the fan sits. I just chose to leave it off and have not had any issues.
Is that what you’re experiencing as well or are you having a different issue? Would be interesting and helpful to see pics of the problem too. I’m sure we can figure out a solution.

I am waiting for a pack of various standoffs and washers to arrive in the mail, then I will try again and post pictures, thank you! Like you @jtemple967 I did not install the standoff in the corner. My issue is…the black casing of the Audio In and Out of the PiSound rests on top of the fan, and then the fan can’t spin.
