Hello all,
I wanted to share some insight here, and maybe get some feedback. I contacted Supermicro support about system noise levels.
The case I am intersted in the CSE-836TQ-R500B here:
http://www.supermicro.com/products/chassis/3u/836/sc836tq-r500.cfm
(I might also look at a similar situation with the 24-bay model)
According to support, these are the noise levels:
* Two FAN-0125L4's (back) @ full power these put out 47 dBA
* Three FAN-0126L4 (front/middle) @ full power these put out 53.5 dBA
If you set fan mode to "optimal", the dBA for each fan will be around 28 dBA (using a Supermicro motherboard)
These fans are indeed loud otherwise.
Power supplies:
For the 94% efficient platinum, redundant 500 watt unit PWS-501P-1R
@50% load 16 dBA
Under heavy load, max is 29 dBA
So, the power supply is no problem at all, even under heavy load 29 dBA is fine, but it is probably high-pitched.
The issue is really the case fans. I think part of the issue is that they are not only cooling the hard disks, but using the fan shroud and passive CPU heatsink(s) they are cooling the CPUs as well, so it would not be that hard for them to need to spin up higher than the 28 dBA point with modest loading.
Here is my thinking:
* I plan to use a Supermicro X9SRH-7F here: http://www.supermicro.com/products/motherboard/Xeon/C600/X9SRH-7F.cfm
* This motherboard is on the compatability list for the 16-bay case SC836TQ-R500B so all the features will be supported
* Don't use the fan shroud, and use a Corsair H60 water cooler, or similar
* I am using 1 CPU not two, and with an active cooler of it's own
* I will not be using any high-speed / high heat SAS hard disks
* If necessary, swap out the 5 80mm fans with slower/quieter one's, but still use 4-pin one's that work with motherboard control
I have seen many postings complaining about the noise of these. I am starting to think that this is mainly due to not using them with a Supermicro board, and possibly using some of the other non-plantinum power supplies that might be louder. This power supply is fine, and the case fans seem easy to mitigate, or are possibly even fine as they are if you can run in "optimal" mode most or all of the time.
Any thoughts on this?
