Suggestion for rackmount fanless case for A1SRi-2558F



  • I am looking to build this but prefer to mount them in existing relay racks rather than buy shelves.  Any suggestions?

    Also I like to use these if now rack.

  • In a 1U rack mount case often the hot air will be not pushed away and the case will be heating more then
    it should be. To get a silent and fan less board and a fan less case are often really different each form another!

    Please think about if you will get a 1U unit if there is not ventilation in side it could be that the parts on the board
    or inside of the case could be damaged. And often those constructions will be based at home and many peoples
    are thinking it will be only for a home set up is really against this doings! Because inside of business used racks
    are often a separate cooling is installed or the racks are placed in air conditioned server rooms, so it will be more
    important to have this in a home usage case then a business usage.

    SuperMicro is selling two different 1U cases for this board, what is with them?
    Rear I/O ports
    Front I/O ports

    As a work around I would really consider to use a 2U or 3U case, then you will definitely not needing
    any fans in this case. There will be then enough space for the hot air circulation.



  • I was thinking something like this.  And especially if set vertical using that wall mount rack air would naturally flow.

    And then use this psu instead if the onboard.

    The onboard could be a backup if the primary failed.

    Is this a sound plan?  I would think their would be plenty of airflow.



  • Without a fan my A1SRi-2758F gets quite hot. I think it is not good to run it fanless.



  • @kapara:

    Not at all!
    There's no chassis fan so why would you expect a flow? Some convection cooling will occur but that's limited.

    A 1 RU fan running at 4.000-6.000 RPM is making quite some noise and will last 2 - 2,5 years.
    A 2 or better 3 RU fan moving the same amount of air is hardly audible and lasts a decade.

    So why do you want to squeeze it in a 1RU enclosure and mount that vertically?

    And on top cooled part are living longer and will be acting in its technical made area.

    Some very cheap Sunon fans will be really quite, but there fore often more then one are needed to cool all
    down to a accommodate temperature.

    1000 times better then 1U without cooling parts.

    Yeah this might be a reall good question as I see it also right.

    Not only yours, and the RAM and SSD will do the rest in any kind of case like mini-ITX or 1U form factor.



  • I'm using the same board inside a 1U Supermicro case for a little bit over 120 days now. Without cooling the C2558 runs idle at over 53°C. So I put two Noiseblocker XM1 inside it and now the C2558 runs idle at 32°C.



  • I would think with the design of the supermicro 1u case and having it mounted vertically convection would create airflow.  The case is completely porous on the back and front.  So I will probably get it with the fans and try using it without and as mentioned if it runs to hot I call always re-connect the fans.  Thanks to everyone for the advice and suggestions.
