HP Proliant ML350p G8 Watercooling!

Recommended Posts




Thank you for that!


What I currently have completed is stripping the two ground and the one PWM wire (from a 4 pin sata power cable with the same color layout that plugs snugly into the female socket ignoring the blue frequency wire. Didn't want to cut any wires on the fan chassis just in case it didn't work) and put a twist on wire connector on the ends with shrink tube holding all 3 wires together. 


Did this to the first fan in the assembly and tested it with FAN1 removed and everything is working as expected! 


One thing I do not understand is how the PWM signal is being spoofed with no hardware/software manipulation and checking the speed of FAN1 via SpeedFan, the RPM of FAN1 is the same as all the other fans (just curious). 😐


Never the less I will be working on this further over the weekend, installing four new 2500 RPM fans at 31 dB (Scythe DFS922512M-PWM) and creating a custom fan shroud in order to have the two fans in the middle push air directly through the CPU's for better temps. A type of wind tunnel effect. I have heavy heat temp graded thin plastic that should work perfectly for the design. Hopefully that will keep things cool. Will do a couple monitored stress tests in order to make sure that the fans can handle the workload. 


Will keep you posted with photos. 


Thank you!

      I'm new to the HPMSG8 world and so far I'm loving it. I have a stock Xeon with 16G of aftermarket memory with iLO patched to 2.70. Next up is adding a RAID card, so I can put my boot SSD on the onboard RAID. I picked up a LSI SAS9211-8i on Amazon, but am struggling to flash it to IT mode on the MicroServer. Is this even possible? Unfortunately, the only other system I have with PCI slots is 32-bit.
      Any pointers would be greatly appreciated.

      Hi there,
      I hope this topic fits here just right.
      So a few days ago, I moved my Microserver Gen8 to a friend's place and resetted it.
      When we set it up with new disks, the raid-creation in OpenMediaVault (Debian 9.6) failed.
      `smartctl` tests passed just fine though and vendor-tools also didn't report any drive errors.
      What happened?
      - I start the Raid creation via `mdadm` and after a while (random blocks and times), it fails and the second disk seems to fail (e.g. sda and sdb are creating a raid, then sdb gets "kicked out" and reread as e.g. sdd, sometimes even with only a few GB of space instead of 3TB).
      I tried attaching the second disk on ata2 and ata3, but it keeps failing. The one on ata1 works just fine though.
      I tried different disks and vendors, but get the same results.
      There are some errors in `dmesg`, but I don't know what they mean. I pasted them here: https://pastebin.com/raw/XASQJ6cy
      What I did here: I stopped the raid to re-create it, but then didn't do anything for a while and the error still came up.

      Can someone help me with this? (As a wild guess, I'd say that somethings wrong with the SATA connections at least on ata2 and ata3).

      Thanks in advance

      Wonder if anyone can point me in the right direction here. Have just replaced the CPU on my gen 8 microserver. Went according to the video above. Upon booting the server up, there is a clicking sound coming from the main board. Regular as clockwork, and the server isn't posting. Any ideas? I've swapped back to the G1610T CPU, but still the same issue. And just make it interesting, I don't have access to a monitor or keyboard.

      Hello! Recently I've been thinking to upgrade the CPU in my HP ProLiant ML10 v2. It currently has a Intel® Pentium® G3240 (I got the model of this server that comes with the Intel® Pentium® G3240) and according to the manual I should be able to upgrade the CPU to a Intel® Xeon® E3-1220v3. Is this true? Do I need to change / get anything else? Thanks.

      After reading a lot of stuff here and there I am planning some sort of investigation... I'd like to make a board adapter to make Microserver work with any 120mm fan (PWM or DC regulated) without problems and failures. I know some members got problems when installed a new fan and tried different connection schematics.
      Here's what I'd like to do:
      6pin HP connector <-----cable----> adapter board with MCU   -----> 4-pin fan connector (+ 6-pin HP-compliant one for backward compatibility)
      Desired functionality of MCU board:
      1. Working rotation detect with any fan based on rpm counter.
      2. MCU-based rotation speed regulation using both PWM and DC modes to allow support for any fan. DC controlled fan low-voltage cutoff detection should be included.
      3. "First-run" mode to check to lowest voltage and detect PWM-DC fan control functionality.
      I couldn't find some information:
      1. What 6-pin connector type HP utilyses to allow the board connection to Microserver mobo as I wouldn't like to disassemble the original fan?
      2. Have anyone tried the rotation detect imitation (having a 6-pin custom connector and a potentiometer would let me do that)?
      3. Can you help me to collect some information regarding the issue in this topic to make things easier as I can say there's 5 or 6 topics only on Reset and I also find some info on HP and other related forums?
