Noise and Thermal Testing, IGP

I'll admit I had some reservations about the cooling potential of the SilverStone Sugo SG05. While the 120mm intake fan more or less has a straight shot to the back of the case, the power supply comes installed facing downward (meaning the intake potentially competes with the CPU's heatsink), and the inevitable cable spaghetti may interfere with getting that air to the processor. As it turns out, I didn't have a whole lot to worry about.

Noise and thermal testing for the SG05 was done with ambient temperatures between 25C and 26C; it's pretty hot in California right now, and I can't exactly run the air conditioner during testing (just before and after).

CPU Temperatures

SSD Temperatures

The SSD is essentially passively cooled by being next to a giant vent, but that doesn't seem to be an issue. Meanwhile the airflow of the SG05 is able to produce excellent thermal results for the CPU; Cooler Master's Elite 120 may have a 120mm intake fan as well, but that fan is blocked by both the front ventilation design and the drive cage behind it. The SG05's intake has much less interference.

CPU Fan Speed

Fan speed is also quite good; the SG05 has a reasonable amount of headroom. Keep in mind that the only two cases beating it in thermal performance are both a good amount larger; in terms of volume the Prodigy is nearly three times the size of the SG05.

Noise Levels

That copious size has another benefit for BitFenix's enclosure, though: it keeps the noise down. The SG05 runs pretty quietly, though, and an enterprising user could probably get noise levels lower by using a quieter intake fan as well as more aggressive fan control on the CPU's heatsink/fan unit. In fact, the cooler we use for testing has a switch on it for exactly that purpose.

    Could you do a comparative review of the some of the mini-ITX cases(thermaltake, coolermaster, silverstone, lian-li and bitfenix) available in market? as most of these cases look similar on the outside(except for the bitfenix one) I am interested to know how they stack up against each other in terms of usability and cooling performance.

    yes, would be nice.

    As far as I know, there isn't a better form factor + cooling concept case than the SG05 and its sucessors.

    So, why haven't I bought one?

    Cause Silverstone doesn't give them a nice build quality. Its iron, its got sharp edges inside and the plastic front had a crummy fit.

    By far the greatest annoyance is, that Silverstone forces you into a crappy, non-modular PSU! Why oh why would you ever use a non-modular PSU in a tiny case where you want to avoid extra wires obstructing airflow???

    A few years back, I went so far as posting the measurements and concept to Lian Li's support site, asking them to please make a form factor like that, so that we could finally have a high quality, slightly elongated version of the SG05...

    n13L5,

    I share your frustration towards the build quality of the SG05 and have plans to address the demand for an aluminum alternative to the SG05 (Kickstarter + batch custom order :p).

    I'm interested in knowing 1) what Lian Li told you, 2) how serious you are about getting a new mini-itx case.

    Let me know

    Modular PSU's take up more space because of the connector to the PSU chassis. When space is a premium, an extra inch or so can make a big difference in such a small enclosure. Plus it's easier (cheaper) to get higher effeciency in a PSU that is non modular due to resistive losses from extra inter connects. Not saying it cannot be done (obviously it can), but it would make the PSU more expensive, and the case it comes with more expensive.

    Personally i prefer steel enclosures. The weight difference is negligible once you load it up with electronics, but the steel panels resonate sound less than aluminum panels. Plus steel is cheaper. I know a lot of people in the silent PC field who HATE aluminum enclosures with a passion for this very reason and refuse to buy them. So while making it aluminum might make some buy it, it will make others not buy it, and in the end only result in a more expensive overall product.

    Now i do agree a nicer (aluminum) front panel instead of plastic would be nice. Wouldn't affect sound quality since it would have steel behind it, and should only increase cost slightly, but make it look much more professional.

    You have to remember, nothing is ever going to be perfect for everyone, and so they have to make compromises hoping to appeal to the widest possible group of potential customers. For the last 5 years or so, the SG05 has been the standard all other ITX enclosures are compared to, so i think the compromises Silverstone has made were the right ones.

    n13L5,

    If you are still looking for an alternative to the SG05, I started a project with the help of Lian Li and SilverStone to build an alternative to the SG05.

    The NCase M1 is impressive. I hope you are able to achieve a production run. I'll support a funding effort.

    holy mother of god i just stumbled upon the meeting of the ncase m1 team

    and now I, too, bear witness on this union. Can't believe I stumbled upon this after all these years.

    I sprung for the sg08 and z77, design is very similar and due to the 130mm fan needed a right angle slimline SATA power adapter.

    Thank you Dustin for another excellent review.

    I like the appriciative style for the product and the consumer oriented approach instead of a hysterical or hidden angry style.

    Mini itx cases is an interesting product at the moment. Ib and 28nm gpu iis one thing, but performance on many other components is just not interesting anymore. Who gives about 400Mb/s ssd og 550Mb/s or 60 or 90 iops, in an workload only a minority uses very seldom.

    One of the forum members have a powercolor 7550 running inside a sg05, forum is down for maintenance now, so no link.

    I am very interested in this case, but would like to get noise down. Can i just fit silverstones own 12mm low noise fan instead? or what else is needed?

    Any chance silverstone will upgrade to the gold standard ps?

    If this can be a message to silverstone reps, can we have a lower noise, higher efficiency deluxe version ? :) - i mean its pretty cheap as it is, you got all the other parts in house come on !
