![]() Rear exhaust: x1 SilentWings 3 140mm High Speed P.S.Frontal fans: x3 SilentWings 3 120mm High Speed This way we will have 100% air in and out from top exhausts. I wander if you will continue passive cooling or will you move fan to bottom to blow in on to CPU heat sync. ![]() I’m sure you will take advantage of raspberry pi PCIe interface you might reduce 2 HAT boards to 1? And please make more space between raspberry pi board and your board so we could have some heat syncs to those chips on argon motherboard as they getting really hot too. You could instead of USB 3.0 port build m.2 connector instead standing upright longitudinally as shown in picture. I hope with raspberry pi 5 having PCIe interface we no longer will use USB bridge. This way we will be able to attach heat sync and have better airflow. My second advice is please move internal USB 3.0 port away from back wall and place it longitudinally as in this picture: ![]() So Argon designers for raspberry pi 5 please have some “exhaust” chamber separation after fan so 100% of air is pushed out removing heat away and not circulated inside accumulating heat. My room temperature is 73F or 22.8C I’m sure I can have second 3.5 HDD and it will not make any issues. My CPU never exceeds 35C and neither HDD nor SSD exceed 37C. Throughout of all time fan kicks in for about 40 sec with interval of 1-2 mins with speed of 25%. So I had all covers closed and installed openmediavault and now watching movies from minidlna. I’ve flashed Debian 11 to SSD using pi imager and installed it to Argon EON case together with HDD wich already had some filesystem with data. My /dev/sda is m.2 PCIe NVME SSD Kingston A1000 240 Gb on (NVMe to USB Adapter M.2 SSD to USB 3.1 Type a Card with RTL9210 D Enclosur Q8M8) and my /dev/sdb is 3.5 Seagate NAS 4Gb HDD 7500 Rpm. Screenlist = clock cpu storage bandwidth ram temp ip This way instead of inefficiently circulating air inside where, according to my opinion, about 20% of air is escaping and 80% is circulated, with my exhaust chamber separation 100% of hot air is being pushed out and cold air is coming in from the bottom intake. I hope this helps someone, especially if you have your NAS full with 3.5 drives.Īs you can see in this pictures I used a Gorilla tape to separate inner chamber before fan and “exhaust” chamber after fan. I have no affiliation with this fan, but here is the link if anyone is interested. The bottom fan is 120mm, not silent, but much more quiet. Much happier now, notice the main fan is off at the moment. I bought this USB-powered fan off of Amazon with a flat top and legs to blow air upwards (plugged into a UBS 2.0 port on the EON. I also have a 500gb USB/NVME (/dev/sdb) inside, so… yes it’s full and hot. I have 2x3.5" WD NAS drives and 2x2.5 Seagate Barracudas. I just installed the updated scripts from NHHiker and I am finally overjoyed to get some relief. I finally setup my Eon and the fan noise was driving me crazy. Hi, I just wanted to share my experience. 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. 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. ![]() (2) Argon Config - We have added a sub-menu for Users to SET the FAN Triggers based both on the HDD and CPU temperature. Future buyers will receive their units blowing outwards. Thus we recommend that Kickstarter Backers flip the FAN. (1) FAN Direction - Based on more recent test it is better for the FAN to blow outwards/upwards. In light of the discussion in this FORUM we made the following changes: At these temp ranges most manufacturers would rate their HDDs to work safely. 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. Your input to this Forum is well appreciated by Argon40 and I am sure the community at large. First we would like to acknowledge the support and feedback of and which was very helpful as we continually improve on the Argon EON.
