I just build a new unraid (v6.1) box. My old system was running low on space so time to upgrade.
Chassis is the Silverstone DS380
HDs are 8 of the Seagate 8TB archive drives.
Controller is the Supermicro AOC-SASLP-MV8
MB is a Supermicro X7SPE-H-D525
PSU Silverstone ST45SF
I read through the various posts on this chassis looking for info on the cooling issues with this chassis. Other than the use of some cardboard to control the air for the 2 side fans, I didn't find much. So I decided to do a test.
With the stock cooling and a parity check running I had the following temps:
38,39,37,39,43,46,46,42
Ouch! Thinking about air flow I decided to force more air through the hard drives. I plugged (w/piece of paper) most of the fan intake for the HD fans on the side of the chassis and left the front door open.. I saw a huge drop in temps. So I've done the following:
2 Side fans are disconnected and their opening is fully covered.
Openings above the card cage/PSU closed off.
Card cage opening metal bracket holes plugged.
Chassis opening next to PSU blocked off.
I now have only 1 fan, the one on the back blowing out. Incoming air comes in either through the front (cooling the HDs or through the PSU.
Temps are now (parity check running):
36,33,31,33,35,36,37,36
CPU: 23
MB: 37 (not sure if this is right). - sorry, no before temps for MB/CPU.
Room temp is 20C.
System is much quieter and temps are stable.
As best I can tell, these are good temps for HDs during a parity check. I perplexed why Silverstone would go through the expense of adding the side fans when the chassis seems to work better without them.
Now I need to determine how to permanently remove the front door.
Note: The 1st HD temp is the parity drive.
