Streacom Cases and Silent PC

Postby DJS » Mon Nov 10, 2014 23:22

Preparing to re-house my main PMX workstation into a silent case to remove PSU and case fan noise from editing suite (aka bedroom :? ). The Streacom cases seem the best engineered option that I can find, I think they are presently being used by Merging in their turnkey PC's.

Wondering if anyone has built one with a hot processor, eg 4770K i7, and if they passively cool sufficiently. I notice the 4770K TDP (thermal design power) of 84W is below the 95W total defined for the Streacom F10 cooling system.

How have your silent case experiments gone?

I built a new PC in February 2014. It's primary purpose was video editing however. It runs the Adobe CS6 Production Premium suite. It's an Antec P183 case, an Asus Z87 Expert MB, an Intel i7 4770K, a Zalman cnps10x optima CPU cooler, a CoolerMaster M2 850w power supply, and I replaced the Antec case fans with Noctua NF-S12A fans. Oh, yes, it's got an NVIDIA Geforce GTX760 graphics card in it.

The PC is very quiet, but not silent. The case is nice, composite panels are very quiet. It's sitting on my desktop, my left ear is 55cm from the front panel. So yes, I can hear it. But it's a very low white-ish noise, no hums, no peaks. IOW, the quality of the noise is good. Without the GTX760 it would be quieter I'm sure (it's using 400w all by itself, and running two additional fans). And if I'd actually set it on the floor and put a sound barrier around it, it would be very hard to hear.

The thing about the 4770K is that when you stress it, it gets very hot very quickly. Lots of stress is going to require lots of cooling, or it's going to result in internal downrating of the CPU (it will slow down to reduce heat). I've read that the 4700K responds well to liquid cooling systems, but I'm not willing to go that route. I suspect that the i7 4770K is not the ideal CPU for an audio computer, but it works great for video editing.

I'm thinking actually that a i5 might be what Pyramix needs. Lower power, much lower TDP, and I doubt that Pyramix or any of the top end DAWs need or would use the horsepower required to do video editing except in extreme cases (lots of channels at very high sample rates?). But... actual numbers have been hard for me to find.

I'm thinking about this stuff right now because I'm thinking about a laptop computer for Pyramix for location work. So any numbers you've got on what Pyramix needs would be helpful if you care to post them.

The big issue here is that once you do all the stuff to configure the system to perform best with PMX, the TDP will be at the absolute maximum of these fanless chassis. This is why Merging is using the i5 version of the processor.
Also, there are clearance issues with heatsinks on some mother boards. They get in the way of the heat pipe.
All the best,

Thanks Mark. My CPU use with PMX is always pretty low, especially during recording. What operations in PMX would cause an i7 to output more than its average heat.

Normally on production machines you disable SpeedStep and adjust the C states for optimum performance. This causes the thermal load to rise but has a remarkable effect on system performance.

I was under the impression the i5 was recommended since it has an equivalent in the i7 series, but without the extra cost of Hyperthreading. (MassCore doesn't get along with HT).

I'm sure your point also is valid from a TDP perceptive.

We also purchased Noctua, along with Gelid fans. They will be installed soon, when we get to the remainder of our PC upgrades/updates.

A colleague has just built a media PC with Noctua fans, they are still too noisy for a desktop workstation for mastering. I think the completely silent cases are the way to go for this application.

It seems only the i5 S series (65W) has significantly lower TDM than the i7 (88W), apart from the mobile T series.

Streacom may be something to look into for our next build. However with Xeon CPUs etc. would need to do more research.

Would you happen to know what Noctua fan model your colleague has installed ? Different options are available, optimized for various purposes (ULN, FLX, PWM), as well as decreased noise with the use of the L.N.A adapter.

We haven't yet installed ours, and thinking of changing optimization.

He got two of the extra slow 900RPM fans.

Lowering the speed is one of the most effective ways to reduce fan noise as the noise is proportional to a high power (??) of air velocity

Just moved my 4770K i7 to a Streacom FC10 case and I used one of their new ZF 240W silent power supplies.

Working well with PMX, CPU temperature is stable at around 57 deg C in mid summer in subtropical Australia. Finally having a totally silent PMX workstation is wonderful.

Glad it's working out for you! Is there a recommended temperature target range ? (Above you listed the watts).
If there are any changes with your system let us know. Might consider a Streacom for the next build, just not sure about the Xeons...

For now we will go with Noctua and Gelid fans, and install a fan controller to drop the RPMs further when required.

Looks like MassCore will now support Hyperthreading on 64 bit systems (but NOT on 32 bit systems).
(Pyramix 9.1 Installation guide p16).

This is new to Pyramix 9, thus my above comment holds less merit.

I just ordered a Streacom FC8S Alpha Optical Fanless with nanoPSU (150W), motherboard MSI Z97I AC (socket 1150), quad-core
4790S 3.2Ghz Haswell, 16Gb RAM, and SSD disk. It has been configured by an official reseller of Streacom. The people there guaranteed me that it is enough to dissipate the CPU power. I also added a PCIe Ethernet card Intel Pro (E1G42ET_Dual_Port), so that streaming data through the PCIe bus to the Ethernet is fast. I do not need a special graphic card, so it is low power consuming.

I cannot yet experiment this setup, since I ordered the Merging Hapi 5 weeks ago but still waiting for its delivery. It seems that there is a long waiting list at MT, so no idea when I will get it :(
