Cooling an SG-4680 1U
-
Hello,
My SG-4680 1U is generating considerable noise and I can't move it to a place where noise won't matter.
To solve this, I've been looking for a passive replacement part for the active cpu cooling. Since the machine will be operating under light loads, with few or no add ons and in room temperature, I expect passive cooling to suffice.
Has anyone done this before or would know with what quiet active cooler or passive heatsink the current cooler could be replaced?

The 1u has the PSU built into the case; I would be hesitant to remove the fans cooling everything down.
You should be able to see if it's the PSU or CPU fan that is making the noise.

Have you measured the fans to see if you can find replacement parts?
If it were me, I would contact Netgate support and ask them for the fan specs (RPM, physical measurements, air flow, mother board connector pins, etc.) on this particular model. Then go find some that match, or see if you can order replacements from them directly.

Tonight I had time to inspect. It's the PSU fan that is working in a noticeable sound frequency range.
Although the external psu's can operate without fan, I won't disable the fan in this internal piece.@akuma1x said in Cooling an SG-4680 1U:

The fan in the psu seems to have standard dimensions with 40x40x12mm.
The power wires are soldered or gummed. Cutting the wires and connecting a new fan with a connector block might do the trick.
