SG-2440 operating temperature confusion…

[nahadot]

Hi all,

I am planning on purchasing an SG-2440 or something similar for home use. So i need something with passive cooling or something super quiet.

I was checking the specifications for SG-2440 and i have found some contradicting information related to the working temperature of the product.

For instance :
Netgate website says : 0°C (32°F) to 40°C (104°F)
https://www.netgate.com/products/sg-2440.html

Pfsense store says : 32°F (0°C) to 149°F (65°C)
https://store.pfsense.org/SG-2440/

And a german retailer/partner : 0°C to 55°C
https://shop.voleatech.de/produkt/sg-2440/

This is super strange because the products seem to be indentical and the enclosure seem to be the same.
Can someone please confirm what is the actual working temperature of the product?

Also another question : is the working temperature on the website referring the to the enclosing temperature of the cabinet where the unit is installed? or is it referring to the temperature of the CPU (max value the CPU can reach).

I am very interested in the working temperature because the enclosure i would like to install the product has an ambient temperature in the summer of about 30°C when the door is closed and about 25°C  with the door opened.

I am currently trying to replace my Ubiquity Edge Router pro POE5 and that one is running quite hot (think he is above 45-50°C on the upper part of the metal case).

Thanks a lot,

You shouldn't have a problem running at 30° Ambient.  The CPU is protected by an internal thermal limiter and will throttle back as it gets near the set point.
In the event of a total cooling failure (or operating in a too hot environment): The CPU will signal a thermal trip event, notifying the system to power off.  (There is also
an overtemp register, that records if the CPU has gone into "Catastrophic Thermal" zone (Intel's words from the CPU datasheet).

I personally run a 4860, in the top of a closet in the hottest room in my house, in Texas, which certainly approaches 30C.

Depending on where you are and what your environment is like, i.e. how much airflow around the case etc.
The 2440 is fanless.  A 4860-1U with a fan my be better for ventilation.

Someone will update the documentation (probably a cut and paste error).

My 2240 is in an 85 F or 29 C degree room and the internal temp is shown as 118 F or 48 C. The outside temp of the case is 97 F or 36 C.

There is a 2.5 inch or 6.3 CM pattern of slots in the top of the case that it would be simple to set a small silent fan on top of if you wanted a bit more air flow.

It might cool better mounted on edge as the right and left sides are completely slotted but I haven't bothered as it is happy enough sitting flat here.

It's possible that the different sites are referring to different things - Storage, or Operating temperatures, or bare board (the boards inside are not exclusive to the chassis).

I'd go with Netgate as a reference since they manufacture the units.
