Hi,
The temp metric on system info reflects only the Raspberry Pi CPU temp and not the temperature of other components or boards, or the entire device.
The cmd that's used is below. Divide the result by 1000 to put in human readable format.
cat /sys/class/thermal/thermal_zone0/temp
Tim, out of curiosity… what is yours reading?

On my Katana + Pi-3A+ see below. I only use top, bottom and front panel from the Allo dog bone acrylic enclosure. I set the CPU governor to On-demand in System config and let Linux manage CPU throttling.
Code:
pi@rp3:~ $ moodeutl -m
CPU: 600 MHz | LOAD: 5% | TEMP: 48°C | RAM_USED: 40% | DISK_USED: 35% | FPM_POOL: 3 workers-Tim

Hi moOde fans,
RE: Allo Katana DAC - Tim Curtis - 03-18-2019
Yes, switched to the nice minimalist 3A+
RE: Allo Katana DAC - nassost - 03-18-2019
Mine measures at ~56°C when it boots and at ~66°C after a few hours of usage. I have the full Katana stack, including the isolator, in the Allo clear acrylic case and Edward's Sound tweaks applied.

Dear HannoG,
I am interested in Thel supplies. Would you mind telling me about your experiences?
And what do you think of the Thel Class A "Black Pulsar" supply for the +/-15V rail?
Pi 3B+
Isolator
Katana
Allo Standard wallplugs at the moment
Thel NT25-HQ9?
Thel NT50-HQ9?
Thel BLP10-22?

Maybe!

RE: Allo Katana DAC - deafnut - 03-23-2019
HannoG (audioviel?), did you test the Katana with other power suplies for comparison? Thel seems to have upped his prices significantly lately.
Has anyone tried external power supplies for the +/- 15V?
RE: Allo Katana DAC - jonners - 03-23-2019
Yes, external +/-15V supplies make a noticeable improvement. There are discussions on the Katana thread at diyAudio.
