A1SRi-2558, Case M350 and Fan position



  • I have recently built a unit based on Supermicro A1SRi-2558, with 8GB RAM, Intel SSD S3500, picoPSU 80W.

    It serves a home network, with a 10/1 ADSL, 1 LAN (clear internet, 10 clients), 1 VPN (always on, 5 Clients), 1 DMZ (with random access).

    I have positioned the fan, Noctua NF-A4x10 Flex (40x40x10) in the upper case above PSU, blowing directly to CPU @5000RPM. This is one of the 5 possible positions.

    With case closed and after 24 hours of operation I have the following temps, from IPMI:

    Did anyone put the fan differently with best results? Thank you for sharing.



  • Similar configuration here:  Supermicro A1SRi-2758, with 8GB RAM, Intel SSD S3500, picoPSU 80W, M350

    Have a BlackSilent XM2 (40x10) mounted in the same position as you, temps attached.  I found that to be the best position.  I even tried 2 fans, one intake, one exhaust, that did not make much of a difference.

    Jason Litca has a really nice custom air duct setup in another post, can't find it right now.
