Hello,
I'm trying to build a low noise/heat/power/footprint system. Everything needs to fit into a 9U, 450mm deep wallmount rack. This means two or three servers, switch and cable management. The depth requirement limits the options, but the supermicro servers (5018D-FN4T, 5018A-FTN4) and chasis (SC505-203B, SC101i) seems to fit nicely. The front IO was chosen to simplify installation/cabling since there is no side access to the rack.
About 4U will be taken by the nas (NSC-800). Switch and cable management is 2U, leaving 3U for two servers (atom and xeon-d).
In order to prevent hot air reuse and heat buildup, the roof of the enclosure will have one 120mm fan + exhaust duct attached and connected to the exterior.
Not having worked with any of those products before, I'm not familiar with their noise and heat output. Sound dampening technniques won't work very well in this case (glass or vented door) so it would be preferable to have the absolute lowest noise produced by the equipment. The target is below 30 dBA.
The parts list for 5018D-FN4T shows "FAN-0065L4", which is a 40x28mm 13K RPM PWM 52.5 dBA fan. That does not look silent at all.
The parts list for 5018A-FTN4 and SC505-203B shows "FAN-0100L4", which is a 40x28mm 8.5K RPM PWM 34 dBA fan. That seems more reasonable, even though you can install two of them.
The power supply is listed as "200W Low Noise" but without dBA numbers. Worst case, this could be (hopefully) swapped for a SS-300M1U + adapter.
The SC101i has one "6cm 4-pin high performance cooling fan", without part# and/or noise specs.
Now for the questions
1. What is your experience with the above servers in regard to noise? Anyone has audio recordings and/or dBA numbers on idle/load? There is a mp3 recording for 5018A; does anything similar exist for 5018D-FN4T?
2. Which would would be quieter for housing an atom c255X: SC505-203B or SC101i? The SC101i looks good, but the SS-300M1U would be as quiet as a power brick and probably more reliable. Also, only one U instead of two + shelf. The goal is to minimize noise and heat output.
3. Does the 13K RPM fan on the xeon-d chasis spin down to near silent levels for a, say 20-25 deg. C room temperature? What is to be expected (noise-wise) if the room temperature is 30-35 deg. C to begin with?
4. How noisy is the soc fan shipped with X10SDV-TLN4F?
5. Has anyone used a fanless X10SDV-* in a revision N SC505-203B and with what results (heat/noise)?
Another option would be using 2U/3U chasis with 80mm fans, but nothing under 350mm (14") seems to be available. Also this would require a 12U rack, which is ok IF the 3U chasis is quieter.
Thanks.
