I've played a bit with determining the effect of additional fans on the temperature.
In the tests, I've been measuring:
- With and without the left panel (the one on the VPro side) being present
- With and without the VPro cover being present
- With and without additional fan present (used Noctua NF-P14, running at 1200 RPM:
http://noctua.at/en/nf-p14-flx/specification
)
Overall, it appears that the largest positive influence on the temperature has the removal of the left panel.
Without it installed, it is possible to achieve the lowest temperature of the VPro, as well as the fact that it also reduces the temperature of BEDROCK by about 5 C and of NODE by 2-3 C without me doing anything to them.
So, temperature of "4 ODYSSEY" in various combinations (in order of best first):
- Without panel, without cover, fan on top (perpendicular to case air flow): 32 C (image of this setup it attached)
- Without panel, without cover, fan parallel (in the direction of air flow): 34 C
- With panel, with cover, fan on top: 36-37 C
- With panel, without cover, fan parallel: 36-37 C
- With panel, without cover, fan on top: 36-37 C
- Without panel, with cover, no fan: 39 C
- With panel, with cover, no fan: 42+ C (this is standard setup without modification)
Notes:
- I did not examine the effects if the front panel is removed rather than the left panel.
- I did confirm that removing the right panel (one on the CPUs/RAM side) quickly increases temperature of BEDROCK, and then initiates shutdown. (So as mentioned, removing the left panel is beneficial, while removing the right is not).
- The image of the most effective variant found (reaching down to 32 C) is attached.
Additional mini-chapter:
- I did not find the 3-pin fan connector on the VPro. Instead, I've plugged a dedicated fan control box in between the PSU 12V power and the DVD drive. (I happened to have this fan controller handy:

).
- I actually like this approach best and it does not require modifying the fans since they're connected to a compatible controller.
- The only drawback is that if one wants to replace Tezro's DVD drive with a 1x5.25 -> 4.x2.5 SAS/SATA drive enclosure (such as Icy Dock MB994SP-4SB-1 or Logilink UA0208), then there may not be enough depth available to mount both the drives enclosure in the back and the fan control in the front of the 5.25 slot. (In the attached image, it can be seen that there is only little unused depth remaining between the end of the DVD and start of the PSU, although it might be just enough - didn't try yet!).
oOoO
