Testing Methodology
For testing ATX cases, we use the following standardized testbed in stock and overclocked configurations to get a feel for how well the case handles heat and noise.
| Full ATX Test Configuration | |
| CPU |
Intel Core i7-875K (95W TDP, tested at stock speed and overclocked to 3.8GHz @ 1.38V) |
| Motherboard | ASUS P7P55D-E Pro |
| Graphics Card | Zotac NVIDIA GeForce GTX 580 (244W TDP) |
| Memory | 2x2GB Crucial Ballistix Smart Tracer DDR3-1600 |
| Drives |
Kingston SSDNow V+ 100 64GB SSD Western Digital Caviar Black 1TB SATA 6Gbps Samsung 5.25" BD-ROM/DVDRW Drive |
| CPU Cooler | Zalman CNPS9900 MAX with Cooler Master ThermalFusion 400 |
| Power Supply | SilverStone Strider Gold 750W 80 Plus Gold |
A refresher on how we test:
Acoustic testing is standardized on a foot from the front of the case, using the Extech SL10 with an ambient noise floor of ~32dB. For reference, that's what my silent apartment measures with nothing running, testing acoustics in the dead of night (usually between 1am and 3am). A lot of us sit about a foot away from our computers, so this should be a fairly accurate representation of the kind of noise the case generates, and it's close enough to get noise levels that should register above ambient.
Thermal testing is run with the computer having idled at the desktop for fifteen minutes, and again with the computer running both Furmark (where applicable) and Prime95 (less one thread when a GPU is being used) for fifteen minutes. I've found that leaving one thread open in Prime95 allows the processor to heat up enough while making sure Furmark isn't CPU-limited. We're using the thermal diodes included with the hardware to keep everything standardized, and ambient testing temperature is always between 71F and 74F. Processor temperatures reported are the average of the CPU cores.
For more details on how we arrived at this testbed, you can check out our introductory passage in the review for the IN-WIN BUC.
Last but not least, we'd also like to thank the vendors who made our testbed possible:
Thank You!
We have some thanks in order before we press on:
- Thank you to Crucial for providing us with the Ballistix Smart Tracer memory we used to add memory thermals to our testing.
- Thank you to Zalman for providing us with the CNPS9900 MAX heatsink and fan unit we used.
- Thank you to Kingston for providing us with the SSDNow V+ 100 SSD.
- Thank you to CyberPower for providing us with the Western Digital Caviar Black hard drive, Intel Core i7-875K processor, ASUS P7P55D-E Pro motherboard, and Samsung BD-ROM/DVD+/-RW drive.
- And thank you to SilverStone for providing us with the power supply and SATA power cable.

"I also think Antec is having the same problem with the Solo II they had with the Sonata IV: it's priced right out of competition. At $129 it just doesn't make sense."It makes sense to people who value silent computing. With the right part selection you can have a powerful computer that is also very quiet and that what makes Solo superb even at $200 price point. Comparing Solo to Sonata is like comparing apple to an orange. Key word: part selection. A proper review with anechoic chamber measurements would show a clearer picture.

@ $120 the Solo II is (IMHO) grossly overpriced.@ $200 it's highway robbery and anyone who would buy a Solo at that price point deserves to get ripped off.
If I have $200 and it HAS to be spent on an Antec case, I'd get one of the 18x variants. Otherwise, I'd go with another brand name.

I agree, I have Antec NSK2480 for years and I didn't buy it because it was fancy, featured some neat mounting system or whatever else.I bought it because it looked simple, and was made of thick steel, that helps to make my computer quiet.
Nothing else counts for me, and that enclosure is doing great job for me... Oh wait, I had to turn off all the blue LEDs on it, because I hate them. ;)

Anandtech just doesn't have the facilities for a proper sound related review of hardware. For that SPCR is a better place to go. If quietness is a priority then that's the place to go for reviews. I've found that their case reviews are better than those here. I'm sure they'll review this case and I look forward to hearing their input.BTW, I have the Solo, and it's a great case! It has it's little foibles, but it's significantly cut down on noise in my office.
As far as tool-less design is concerned, remember that a case like the Solo is geared towards noise reduction. It's possible that some of the tool-less designs lead to extra vibration. Or maybe Antec were just cutting corners.The suspension straps are just the best at reducing HDD vibration transfer.

"Anandtech just doesn't have the facilities for a proper sound related review of hardware.

Not everything is made for overclockers, storage servers and HTPC.

I stand by my conclusions.Just because we can't invest in a custom built anechoic chamber that produces noise level results which border on academic for 90% of end users, I'm somehow not qualified to be doing these?
davegravy - Tuesday, September 6, 2011 - link
Acoustic Engineer here.Results can be significantly skewed by not measuring in an anechoic environment due to room modes. We're talking on the order of several dB.
Your measurements may still be useful for comparison purposes, provided your transducer location and the location of equipment under test is EXACTLY the same for each measurement. In this case, one should not compare Anantech's results with other published results.
Dustin Sklavos - Tuesday, September 6, 2011 - link
That's basically it. I'm confident that my results are comparable within their own ranks.dhanson8652 - Tuesday, September 6, 2011 - link
I think this is a fair review. I have no major problem with this review and I've been a SPCR regular for almost a decade.Suspension was a big deal with traditional 7200 RPM drives back in the day. With SSDs taking over it becomes less and less of an issue. I'd be fine with suspension taken out of the Solo if it dropped the cost and that was reflected in a lower price for the consumer.
The biggest negative you didn't mention is the power button / reset switch is pretty cheaply made. See the picture in page two of this thread http://www.silentpcreview.com/forums/viewtopic.php... I've seen ham-fisted users bust the power button on a Solo and I've had to fix them so it's not an issue I'll quickly forget.
The one thing that I didn't know before reading this review is that the support bar is removable. There have been some on SPCR that have cut the bar away in the original Solo so having it easily removed/replaced without damaging the cases resale value is a plus.
On the topic of intake the lack of intake fan, considering Yate Loon 120mm fans are only $3 retail (less for someone like Antec to buy in bulk) It'd be very easy to up the included fan count by one if they are going to keep the price that high. As is die hard SPCR types don't use front fans.

The really important difference between this review and the SPCR one isn't the precision of the noise recordings. It's that when SPCR found the stock Solo II struggling under load with a mid-range GPU they went ahead, put in a 120mm intake fan and retested. Apparently the Solo II was not only much cooler but quieter with the second fan while under load. Now it would be very fair to slate the expense of what's arguably a $15 hidden extra on the price of a $130 case, but it's faintly absurd not to confirm that the case works well in a two-fan configuration. I understand the desire to review the item as delivered and not to consider esoteric modifications, but throwing in a 120mm Nexus is not exactly drilling holes: it's a ridiculously straightforward and obvious option when self-building a desktop PC for superior noise *or* cooling performance.
