Noise Benchmarks

We used an SPL meter with a sensitivity of down to 30 dB in A-weighted mode to measure noise levels. While it may not be the most realistic placement for the meter, measurements were taken at a distance of 12 inches. Some of the units were quiet enough that the sensitivity of our SPL device would come into play if we placed it at a more appropriate range of one meter. Noise tests were also taken with and without the X800 Pro installed; integrated graphics were used if available, or an add-in MX440 card was used where integrated graphics weren't available.

The maximum noise level measured is a true "worst case" scenario, and the only time that we measured this level of noise was during the POST sequence when the fans spin at maximum RPM. The minimum noise level is just that, while the stress test measurements were taken while looping 3DMark03 after it had been running for 30 minutes. For tests without the X800 Pro, we omitted the stress test and simply reported the noise level after the computer had been running for 30 minutes. Room temperature was 71 F, so there is the potential for higher noise levels during the summer months.

Please note that decebels are a non-linear measurement. Depending on whom you ask, a 3 dB increase is a doubling of power while a 6 to 10 dB increase represents a doubling of the noise level. You may or may not notice a 3 dB increase, but anything more than 5 dB is perceivable, and 10 or more dB represents a major difference.

The noise levels without a high-end graphics card were mostly off the charts, so you could read that as "less than 30 dB" for most of the units. Under load, they can still be audible, but only barely. If you want a quite computer and you don't need a powerful graphics cards, most SFF systems perform very well.

    Hi, How about the dual Opteron Iwill, that keeps flashing on the right.

    there is an ideq with an embedded c3 proc that i would love to see a review of.

    I'd been looking at that Biostar SFF, as its specs are better than the equivalent Shuttle version, and is much cheaper. And now you drop a great review for it! I think that both I and my brother are going to use it for our new systems. Thank you for the kickarse review!

    #6 - fixed, along with a few other things I noticed. If anyone sees anything else, feel free to drop me a line.

    #7/#8 - both of those are on the list of S939 systems we have coming for review. (We haven't received the PCIe one yet, but it should arrive sometime soon.) Unfortunately, most of the "high end" SFFs that we currently have are S775 for whatever reason. I think we have eight 775 units and only three 939 right now. I'd really like to see additional S754 units as well, since Sempron is moving in that direction.

    I think one of the reasons that we're seeing more Intel SFFs is due to the chipset support. 865G is really almost the same price as 865PE, so the integrated graphics are "free". They're not good for gaming, but for most other tasks they work well. The only AMD platform chipsets with IGP are currently the outdated VIA K8M800 and the SiS stuff, although there are some newer offerings.

    In case any of you aren't aware of this, we really can't afford to simply go out and purchase every item that we want to review. Since the reviews are basically "free" advertising (although if a unit has serious problems, it may not be good), the manufacturers have to send us the parts. In case any manufacturers are reading this, get in touch with us and we'll be happy to review any of your SFFs that you send our way! There are quite a few manufacturers that aren't currently represented.

    Im hoping the SN25P turns out to be reliable unlike the SN95G.

    That and the way the PCI-E cards are facing the opposite direction makes me wonder about heat with both slots taken up. Hrmm....

    AT - don't even consider doing your high-end round up until you have the new nForce4 P-series Shuttle due to be released at the end of the month.

    i would also like to see the nForce3 G5-Series Shuttle compared against it, and other high-end SFF chassis'. :D

    WAU, that is one massive review! Good work guys.

    Just one typo to point out on page 8:

    The iDEQ doesn't include any notable extras **included**, but it does have all of the high quality standard features that we like.

    There was one more "it" that shoud have been "if", but I forgot where it was. Sorry :-)

    I thought this article would include a MAC mini, but I guess that will be a separate article altogether.

    If I may, I would suggest you only focus on SFF systems which stand out in a positive way and stay clear of the ones that don't. Just seems like a lot of pointless work.

    Been waiting for anand's SFF reviews. Looking forward to the A64-939 / Intel 775 review that I'm sure will be next.

    arswihart - Note that the SB61G2V3 is Shuttle's latest socket 478, Intel-based system. All of their newer products are socket 775 which will be in a later review. However, I think there are plenty on the AMD side that could've been covered instead that are socket 754...the SN85G4V3 ain't too shabby.

    Absolutely no way that 7 bright blue leds in the Aopen (which only get brighter) should be considered acceptable or "minor" for an entertainment system, in my opinion. My shuttle has only two lights and I've had to cover them up with electrical tape with a small pinhole in order to cut down on the extremely distracting glare coming from it while watching a movie...the orange HD led flashes (as it should) which is even more distracting...

    what the hell were they thinking when they chose to review this obsolete Shuttle system?
