I just got a Hifiberry DAC+ADC and I like it. It's always a bit warm to the touch though. Not scary hot but def warmer than room temperature even at idle essentially. Is it worth doing anything about? I'm running moOde at the moment.
Made a 'tunnel' to house the Pi Hat and Linear supply. Set up fan control and used the largest 12v fan run at 5v. Silent.

Generally speaking, for audio use, Raspberry Pi's don't need cooling. Like most computers, RPi's throttle the processor to keep it from overheating.
Most electronic devices consuming electricity will be warmer than ambient temperature.

Mount it vertically so convection can cool it better? That costs nothing and doesn't make any noise. Hot electronics fail sooner. I've been doing that with WDTV Live media players for the last decade and they're still working.
I have 6 running in and outside with passive cooling with no issues with heat. The outdoor ambient runs over 100 in the summer and the pi’s and class d amps seem to be fine.
RPis can develop quite some heat in warm environments and with HATs attached. If you increase load and run steady overclocking
this will get things worse. Keeping the temperature low and steady is usually a good idea. RPi acting as an oven for your DAC HAT
is not what you're after.
Now. While streaming music e.g. the RPi4 runs usually a single digit CPU load %. My RPi4 - heavily overclocked - never
exceeded 60°C at around 20°C room temperature. On the first glance not an issue.
However.
I do prefer to run the RPi at much lower temperatures. @ << 50°C.
The IMO best and easiest solution is by using an Argon Neo case for the RPi4 .
The whole case acts as a cooling device and still allows to attach HATs properly. Temperatures should stay below 50°C.
Now. There are passive (rather huge) heatsinks out there getting the PI closer to 40°C. I run these on my CM4-Waveshare I/O installations.
In this case you could use GPIO adapters that introduce a 90° angle or a short customizable ribbon cable. That'll apparently enlarge
your device footprint and usually requires a custom case. It also might impact your I2S performance. Adding more stuff to an I2S
connection won't make it better. 😉
Good luck.
