With the large mass of aluminum and the direct contact to the Pi, I was curious what temps were when overclocking.
Test setup:
- Ambient: 23.3 C
- No drives installed
- No fan profile (off)
- Panels on
- over_voltage=6
- arm_freq=2000
- stress -c 4
- 20 minutes runtime before sampling temperatures
Max temp was 55.5 C, seems to average around 54 C.
temp=52.5'C
temp=54.0'C
temp=52.5'C
temp=55.5'C
temp=54.5'C
temp=54.0'C
temp=53.0'C
temp=54.0'C
temp=53.5'C
temp=54.5'C
temp=53.0'C
temp=53.0'C

temp=54.5'C
temp=54.0'C

Hi,
First we would like to acknowledge the support and feedback of @NHHiker and @ghalfacree, which was very helpful as we continually improve on the Argon EON. Your input to this Forum is well appreciated by Argon40 and I am sure the community at large.
Regarding the Hard Disk Temperature, we did some tests and with the Raspberry Pi 4 in IDLE the CPU temp remains at 50C or below (even at our 30C ambient temp) and the mechanical drives were running between 40C-45C. At these temp ranges most manufacturers would rate their HDDs to work safely.
In light of the discussion in this FORUM we made the following changes:
(1) FAN Direction - Based on more recent test it is better for the FAN to blow outwards/upwards. Thus we recommend that Kickstarter Backers flip the FAN. Future buyers will receive their units blowing outwards.
(2) Argon Config - We have added a sub-menu for Users to SET the FAN Triggers based both on the HDD and CPU temperature. Thank you for suggesting this @ghalfacree .
We do not expect the EON case to cool the HDDs down to 30C as the EON’s cooling works like a system, wherein the RPI CPU temp will always factor in terms also in cooling the HDDs. But with ambient temperatures in the 25C or below we still expect the EON to run the HDDs in the low 40C and the RPI below 50C, which would not affect its long term performance of the attached devices.
