Fractal Define R5 Tested at Orfield Labs, World's Quietest
In an obvious PR move, Fractal Design tested the acoustics of their Define R5 case in the anechoic chamber at Orfield Laboratories, widely described as the quietest place on earth. A comprehensive report is posted at their website: http://www.fractal-design.com/home/justsilence
The gist of their report can be reduced to this: A system that measures 28.7 dBA @ 0.5m in free air measures 7.5 dBA lower when installed in a Define R5 case. That seems like a good result, and we rate the R5 highly, but without any comparables, it's not exactly a definitive result. We don't know how much attenuation other cases would provide in the same test.

kewl. I'm guessing WAF will prevent SPCR's lab from upgrading to 0dB(A) reference level. "Honey, I need to excavate for a cellar".

Having spent a couple days at PAX Seattle and subject to 90+ dB game sound effects most of the time, I think there's no need for any such thing. Our chamber's 10 dBA noise floor will already freak out most of SPCR's audience.CA_Steve wrote:kewl. I'm guessing WAF will prevent SPCR's lab from upgrading to 0dB(A) reference level.

Tho I have to admit, my hon was reminding me this morn about when I used to fantasize about building a silent concrete bunker under our back yard.

See - you should have bought a house with a bomb shelter and repurposed that puppy.
It was interesting to note that Puget replaced the front Fractal 140mm fan with a Slipstream 120mm. Also, the effect of the window for 50% and 100% loads.

They use a custom internal fan mount to direct airflow to the graphics card. Older pictures show the internal fan mount uses the Scythe. Pictures of builds they do are posted on their website and it looks like they are using Noctua fans now.CA_Steve wrote:See - you should have bought a house with a bomb shelter and repurposed that puppy.

Their smaller serenity case uses the SG10 which is interesting. The top 180mm fan is removed and blocked. No intakes are used, only a single 120mm exhaust.

Much fewer of those in Canada than in the US. The ICBMs were supposed to crisscross go over us, not land here.CA_Steve wrote:See - you should have bought a house with a bomb shelter and repurposed that puppy.
Yeah, the Slipstream switch seems unnecessary, but perhaps it made some wee difference in the measurements.It was interesting to note that Puget replaced the front Fractal 140mm fan with a Slipstream 120mm.
Really? 0.1 (at idle) and 0.4 and 0.7 dBA differences... I doubt I could hear them.Also, the effect of the window for 50% and 100% loads.

Heh. I must have misread the first time through - thought it was a few more dB.
So, our 1950's elementary school training for "duck and cover" (and then kiss your rear goodbye) would translate to "duck" for you.The ICBMs were supposed to crisscross go over us, not land here.

I am a bit surprised they where able to measure those levels with a Norsonic 121, isn't that below the capacity of that device?
