      I have a very similar SuperMicro board (the A1SRM-2758F), which I use as a PBX and was uncomfortable with the CPU temps as I was using it in a 3u Chassis (for telephony cards).    I found that the CPU cooler shape is roughly compatible with a "Socket G" whatever that is with a 51mmx51mm mounting pattern.

      I found that the Dynatron I2 Cooling Fan fan fits perfectly on this board.
      http://www.amazon.com/gp/product/B004WMCX2U

      It's not perfect, but it works pretty well compared to the stock fan-less heatsink.
      Even when load-testing this system the temperature never really rises anymore.

      Just wanted everyone to know that this cooler is more or less compatible.

          Just completed building the specified hardware and memtest ran fine.  I am able to power the system on using IPMI, but I am unable to power it on using the M350 front panel button.

          I have the cable labeled Power SW connected to the motherboard's Power Buttton header.  The cable labeled Power LED connected to the motherboard's FP PWRLED header.

          Does it matter which pin the black or red wires are connected?  I tried both and I can't power the unit up using the M350 front panel button.

            Not sure if this is the same problem I ran into, but when I built mine, I looked at the header picture on the printout, and I was looking at it upside down, or the picture is upside down to how I was looking at the motherboard.  So I ended up with wiring everything wrong.  It took me a while to realize my mistake (or the printout's mistake :-)).

              Thank you.  That is exactly my mistake too.  I assumed the manual's orientation is correct if I looked at my motherboard in the same way.  It turned out the manual's diagram is upside down.  Now that the wiring is correct, things are working as expected.  I can never figure which pin goes to the red wire and which pin goes to the black.

              I have 3 Evercool 40mmX15mm PWM fans installed with 16GB (2x8GB).  The fans are loud at boot, but then settle down to a whisper quiet 3000rpm.  Its funny the DIMMA1 is 8 degrees Celsius  cooler than DIMMB1 because DIMMA1 is under a fan.

              I am running memtest on the RAM and will get to installing pfSense 2.2.3 sometime this week.

                  Can you point to the website where these fans are available?

                  The fans from mini-box are very load.

                    The fans from mini-box are very load.

                    Evercool EC4015 PWM from Directron.  Keep in mind the fans are 15mm thick compared to the ones from mini-box which are only 10mm.  So there is enough clearance using the bracket that puts the fans over the DIMMA slots.  However, for the front fan, you will need to mount the fan on the external side where the front USB ports are located.

                    You will also need standard PC fan screws since the screws that come with the fans will not work.

                    These fans RPM ranges from 3000+-25% to 10,000+-10%.  Looks like the low end has a wider variance, but they are still pretty quiet.  At boot time, the fan will be full throttle and will sound like jet engines (true server class hardware) so if your router ever gets real hot, these fans will definitely let you know it.

                      HI,

                      Question about the power supply,  I have a 12V5A power adapter, if I use the 4-pin DC power connector and 120W Module,  Will that adapter work?

                      Release: pfSense 2.4.3(amd64)
                      M/B: Supermicro A1SRi-2558F

                        I will say that I am thoroughly unsatisfied with either pfSense and/or this hardware.

                        Using just the initial config, my box will lose its ability to acquire a dhcp lease from my cable modem, a Motorola SB6141, showing a link of 0.0.0.0. If I power cycle, and wire direct with my PC, I get a working address. PfSense was up for only 2 days at a time if that on 2 separate occasions. Tried other patch cables as well. May go back to my ddwrt box as it works much more consistent.

                        The most recent fix was to clone an unused MAC address for the wan, but that no longer works either.

                        Frustrated as this should have much more potential.

                        Also, it seems that many times the unit times out when making changes within pfsense, along with the inability for LAN clients to be pushed my choice of DNS servers. If I instead use the DNS resolver for this, clients show as though my choices are available, but they still only use my PIA VPN DNS. Weird behavior IMO.

                        Note: my pfsense box will shortly (~5 seconds) acquire a default IP of 192.168.100.10 from the Motorola SB6141, but then be assigned 0.0.0.0. It should move on from the internal DHCP to one assigned by my provider (comcast) which is usually 72.xxx.xxx.xxx

                          I remember I had a similar problem, my pfsense router was not getting an IP from my Comcast cable modem.  I am not sure what was wrong.  To debug, I connected a LCD monitor to the video out.  It was displaying "Igb3: Could not setup receive structures".  I did the below, and that error was gone, and I got an IP from my cable modem.  Everything has been working fine since then.

                          @Sir:

                          BTW, I had this error from the VGA output:

                          Igb3: Could not setup receive structures

                          I needed to do this below to get the system to work.  It is from https://doc.pfsense.org/index.php/Tuning_and_Troubleshooting_Network_Cards

                          Intel igb(4) and em(4) Cards

                          Certain intel igb cards, especially multi-port cards, can very easily exhaust mbufs and cause kernel panics, especially on amd64. The following tweak will prevent this from being an issue:
                          In /boot/loader.conf.local - Add the following (or create the file if it does not exist):

                          kern.ipc.nmbclusters="1000000"

                          That will increase the amount of network memory buffers, allowing the driver enough headroom for its optimal operation.

                          To avoid this, only enable WAN and LAN during setup, then go to the shell to create the file (if it isn't there already) and edit it.  I went to the shell (use VGA out or IPMI) and downloaded nano editor (I don't use VI, which is built in already).

                          pkg_add -r ftp://ftp-archive.freebsd.org/pub/FreeBSD-Archive/ports/i386/packages-8.1-release/Latest/nano.tbz 

                          pkg is not part of pfsense.  Follow the steps in this link to bootstrap pkg on pfsense:

                            ^ Tried that on a fresh install, WAN will only get DHCP address from a fresh install, but not consistent at that.

                            Either way, I will not thread jack my problem here. Need to do more troubleshooting.

                              Got pfSense 2.2.4 installed and running on my Supermicro  A1SRi-2758F in the M350 mini-ITX enclosure.

                              Here is my final configuration:

                              Supermicro  A1SRi-2758F
                              Samsung EVO 120GB SSD
                              Kingston  KVR16LSE11 8GB (x2)
                              Mini-box M350 enclosure with 2nd hard drive mounting bracket
                              150w AC-DC Power Adapter, 12v 12.5A
                              Evercool EC4015SH12BP 4-Pin PWM Fan, 40x40x15mm (x3)

                              The firewall is connected to my Motorola SB6141 cable modem with a Comcast 125Mbps/12Mbps broadband.  I did have to set the kern.ipc.nmbclusters=512000 to get rid of the Igb3: Could not setup receive structures error.

                              So far, everything is stable and working better than I anticipated.  Coming from dd-wrt, pfSense is much more intuitive and more responsive.  When I ran MemTest86 with all 8 cores, the 3 PWM fans spun at 7500rpm to keep the system in the mid 40C.  In normal state, the fans spin down to 3300rpm and all is quiet.

                              Now I will be waiting for my fiber gigabit to become available.

                                On what kind of media was you installing pfsense.
                                mSATA, SSD, HDD, SATA-DOM, SSD-DOM, USB Stick,…

                                  Oops, I forgot to specify that in my final configuration.  I used a Samsung EVO 120 GB SSD connected to the SATA3 port.

                                  Anyone know if it is recommended to do a full install on a USB 3.0 flash drive?  I would prefer to have gone this route for fan location reason on the M350 enclosure.

                                    You can safely use NanoBSD install from a USB2 flash drive.

                                      On an USB Stick I would prefer to install the Memstick NanoBSD version.

                                      But with an SSD you are really able to do a full install as you have enough space for all
                                      as I see it right!

                                      And if you want to go with an internally other drive for the most mainboards from Supermicro
                                      are some SSD-DOM or SATA-DOMs out, that is then more something like an install medium
                                      and not even outside plugged in as an USB Stick.

                                          Wow, go with it, this would be a really fast pfSense box as I see it right!

                                          • Enable the TRIM support in pfSense if not automatically done during the installation
                                          • Enable PowerD "high adaptive"

                                          The RAM I would try out as 2 x 4 GB or 2 x 8 GB ECC RAM and not only one module

                                          • perhaps if you go with 2 x 8 GB ECC RAM I would try up to tune the mbufs numbers

                                          But all in all this is a very fast machine and you will be happy with it as I see it right!

                                            I went with 1x 8GB stick of RAM for now so when I upgrade later I won't have to replace 2x 4GB sticks. I can just buy 1 additional 8GB.
