I flipped the fans to pull and swapped side panels so vented panel was on the back side.  Same results more or less.  After 1 hour 15 minutes of parity check - parity drive was as 43C and data drives were at 40-41C.  This was with fans connected to 12v leads whereas tests with fans and panels in standard "push" configuration were running on 7v leads.  So, presumably higher fan speeds resulted in the same results in the "pull" configuration.

Same noise level? Maybe with some sort of fan control it would be tolerable for you under normal everyday use. Just loud during parity checks. Also did you have the filters on or off? When I had the DS380, I did a lot of testing with and without.

 

I believe it was a bit quieter.  Certainly, it was not any louder.  All tests have been with filters on.

 

I emailed SIlverstone to see if I could get another vented side panel.  They also suggested that I try the vented panel on the backside and that I add slim 120mm fans to the panel when placed on that side.  That may improve cooling, but probably increase noise.  Unfortunately, the server is not in a place where cooling is all I care about.  I don't mind a bit of noise, it is just distracting when the server is the loudest thing in the room.

 

I still think the drive cage design is the issue.  There is just not enough air getting through it efficiently.  I will also play around with disk placement as three of the eight bays are empty (and a fouth could be as I just have a spare disk in there with no SATA connected).

I found the source of the noise.  It is the Enermax fan on the bottom! 

 

It is the only fan in all of the swapping around that I never changed.  It is close enough to the drive cage fans that I could not tell it was the culprit.  I now have it unplugged and the Noctuas on the drive cage connected to the MB fan header.  I have configured the fans in BIOS to run full speed and the noise is much reduced by simply unplugging the Enermax.

 

I am running another parity check now and we'll see what temps I get with cage fans on full speed.  I have reconfigured to the standard "push" configuration.

 

UPDATE: Stopped Parity check after 1 hour 15 minutes; parity drive temp was 41C, data drives were at 38-40C.  Full speed fans kept the temps down even without the bottom intake fan and the noise level is back to where it was in the Lian-Li case; quieter than the other computers in the room.  If I need an intake fan on the bottom, I will be replacing the Enermax, it's definitely the noisiest fan in the case.

 

BIOS fan control is based on either MB or CPU temps which don't fluctuate much during parity checks.  I want to control the drive cage fan speed based on drive temps so, I'll check on options for doing that.

Glad you figured out your noise problem. Besides being in the closet, my unifi router and switch drown out the server.

That was the exact reason I started working on my IPMI plugin. Besides getting accurate sensor readings, I wanted to control the hdd fans based on hdd temp. You might try the dynamix auto fan control. Your board may be supported by lm-sensors

Yes, I have it installed and configured and am running tests now.  My board is supported as I have been using the Dynamix System Temp plugin for a while.

 

I have Min. set to 35C and Max. at 40C.  Right now, the fans are running at 300RPM (9%).  I am streaming a movie in Plex and the drive is at 34C.  I'll run another parity check a little later to see how it responds as parity temps increase over time.

It looks like Autofan is doing its job.  When the first drive exceeded 35C, fan speed increased to ~1000 RPM , when all drives hit 35C, fan speed was increased to ~1500 RPM, as temps rose another 1C fan speed increased to ~2000 rpm, then to 2350, and, finally, to full speed when parity hit 40C.

 

Interestingly, the Noctuas supposedly have a max RPM of 1500.  Since I have two connected with the Noctua Y cable to the front fan header on the MB, I wonder if the reported RPM is the combined RPM of both since anything above 1500 is faster than the fans are supposed to spin.

 

After ending the parity check, the fans slowed down in steps until returning to ~300 RPM when all drives were idle and spun down.

 

The only "negative" side effect is that while the drive cage fans are spinning at lower RPM, the CPU temp is higher than usual (nothing outrageous but noticeably higher) as there is reduced airflow through the case.  The bottom intake fan helped as well as it blows upwards over the MB/CPU.  I'll find a quieter fan for the intake and see what impact that has.

 

Basically, my issues are resolved and I have achieved good fan control based on drive temps.

 

With the Noctuas on the drive cage, a Be Quiet SIlent Wings 3 on the rear exhaust and the Enermax disconnected, the system is very quiet now.

The Enermax makes a big difference in CPU temps.  Since I have no PCIe cards installed at this time, the bottom intake fan is basically acting as a secondary CPU cooler since there is unobstructed (except for a few cables) airflow from the intake up to the CPU.  I plugged the Enermax back in to test this theory and after about 15 minutes the CPU idle temp had dropped 7C.

I don't remember if any other y cables came with the noctuas but the one I'm using only senses rpm on one of the fans. I think it's this cable: Noctua NA-YC1 Fan 4-Pin Y-Cable. But that's plugged into a 4-pin pwm fan header. Definately would get another fan for the lower intake.

I am also using the NA-YC1 cable that came with the fans and it is plugged into a 4-pin PWM header on the MB.  Fan speeds reported by Autofan/System Temp plugins must not be accurate because at full speed it is showing ~2700 RPM on 1500 RPM fans.  It's not a huge deal as the speed scaling is clearly happening in reaction to temperature increases/decrease.

 

I have installed a Cougar Vortex CF-V12H fan on the bottom intake and the system remains quiet and relatively cool.

 

I installed the "noisy" Enermax on my water cooler radiator on a desktop PC (The Silentwings 3 was originally there) and it does not sound nearly as loud on that PC.  Sound and temps are good.  I think I have finally found a fan combination that maximizes cooling and minimizes noise in the CS380.

 

Thanks again for detailed documentation on your modifications in this case.  It has been a tremendous help.

Thank you for posting your feedback on this case. I'm thinking of merging two computers (see link) and this case fits the bill as I'm looking to retain a DVD drive.

In addition to making the airflow mods recommended by dmacias in the first posts, below is what I ended up putting in my Silverstone CS380 case:

 

My existing main server (see specs in signature)

 

Athena Power 5.25" to 4 2.5" SSD Backplane - Converts a 5.25" bay to 4 hot-swap bay for 2.5" SSDs (or HDDs) - $43

LG WH16NS40 - UHD/Blu-Ray/DVD reader/writer for ripping discs with MakeMKV - $72

 

Fans:

Noctua NF-F12 (2) on the hard drive hot-swap cage - $20 ea. (controlled by Autofan plugin which varies speed by HDD temp)

Cougar Vortex CF-V12H - bottom intake fan -$12 (I have a 7-volt low-noise adapter on this fan)

Be Quiet Silent Wings 3 120mm -  rear exhaust fan - $22

 

Cables:

Corsair Type 4 Peripheral Cable - power to the hot-swap drive bays - $8

(Silverstone recommends two separate Molex power cables - I used the one that came with the Corsair SF450 PSU plus the additional cable)

Sabrent Molex to 2 SATA - adapter for powering the optical drive and SSD enclosure in the 5.25" bays - $7

Cablemod 24-pin ATX Extension - the PSU cable was too short in this case - $13

 

It's a great setup and I now have room for additional HDDs/SSDa and larger motherboards compared to my prior setup in the excellent Lian-Li PC-Q25 Mini-ITX case.

Hi Folks,

 

I've also got this case and had another idea re cooling the HDDs. What would happen if I also close off the HDD cage on the right hand side with duct-tape, so no hot air could escape to the area below the mainboard (right hand section between mainboard and side panel). As I have blocked off the back of the cage and the side, the only way out for the hot air (with high air pressure) would be to the front (or back to the fans plus anything leaking). I know it's blocked by the trays, but it might be enough to make a difference? Just an idea..
