Powering It Up
Now for the first power up test.
Absolutely nothing happened when I plug in the USB-C cable, the Pi4 stays off. For a moment I thought I have killed the Pi4 with static. Took me a while to realise I need to press the power button first. (To be fair this is my first Pi case with a button button).
Pressed the power button and the unit powered up fine. Now this is REALLY a finished product. The instruction manual did mention I need to download and execute some script first so I did not expect the power button to work straight out of the box.
Noticing the power and busy LED lit up on the front bezel is a very nice touch. The LEDs are not overly bright or obtrusive, and it gives good visual feedback on the Pi’s current working status.
In the short time I have the Pi 4 powered on, the processor is passively cooled by the Alloy case. The top does not feel overly warm to the touch. Either the internal ambient temperature is not warm enough to activate the fans, or the fan itself is broken. 1 out of 3 purchases out of e-Bay end up badly so forgive my pessimism.
Running SnakeoilOS to bit-stream audio in bit perfect mode is not a CPU intensive task so I reckon passive cooling is not going be an an issue.
Passive cooling is preferred as a matter of fact!

Great review TK ! From what I have read elsewhere the plastic base ensures wifi connectivity

Of course! For Wi-Fi. I am too focused in a complete shielding (and properly grounded) of the case, but in doing so will kill Wi-Fi as well. Be nice if they have an option for a metal bottom lid.
I believe the I need to install some packages for the fan to work. So far I think the passive cooling will do me good so will leave it for now.
I’m going to buy a second Argon one soon, will turn the fan on on the second one and then compare. Just looking for a seller with stock.
Also going to fire up the Pi and have a listen to see what needs tweaks work (or don’t). Stay tuned for a new article on that in the following weeks.
