Is this your first time interacting with SPCR?

They have a custom built anechoic chamber that they went through great lengths to construct... Mike Chin is also known to be super critical of component manufacturers, to the point of making it difficult to get review samples...

seems to be a typo. I've asked for clarification.
Indeed, maybe it's been updated already?

My only issue is that noise measurements in an anechoic chamber are the best of the best case. The reflective and resonant rooms that most enthusiasts are confined to not only have much higher noise floors (and just higher floors with lower ceilings), but can boost sound levels 3-10dB due to boundary effects and poor decor choices.
Is there enough room to stand up or do I have to crawl round on all fours like you cats do? biggrin.gif

I'm a member, post and use data regularly. Much of the work done there is good.

Sorry, but what I said about the quote you posted still stands. Anyone doing analytical testing needs to do their writing the same way. The minute they start talking up what they did and bragging, credibility starts swirling down the drain.

Edit: I'm trying to find out what their fan test system is. Their fan test results look very accurate, and they go into great detail about their test instruments, but are very vague and secretive about the physical test system. Again, not being shown makes me skeptical.

Being involved in designing a case means little or nothing. I work with companies all the time with case airflow designs and cooling concepts. So what? I can rub my belly and scratch my head too. Doesn't mean I run fast or jump high.

Who cares. Fans make sound. Turn up the volume and get over it.

Not even standing room. With proper automation, why would you even get out of your chair? tongue.gif

I'll never understand why people expect complete silence from systems where fans are involved. What's the problem, nobody has speakers that go loud enough? Or headphones? Fans make noise, there is no way around that, besides risking product longevity by lowering fan speeds and dealing with higher temps or going fanless and sacrificing power. If you want power, you better get used to the noise or turn up the volume. "If it's too loud, you're too old". Go hard or go home.

Life is not all black and white. There is much more going on in it;s huge gray area/
You seem to think in extremes, have little understanding of how to make a very cool running system that is also very quiet, no understanding why many people do not like noise.

None of my systems make noise above my environmental floor of about 25-30dBA unless they are pushed above 75-85% load levels .. with is rare to never. So while they do make some noise, their noise level is much lower than the normal noise level of the house.
"If it's too loud, you're deaf .. or will be in years to come." Go easy and enjoy what everyone else misses because the are in too much of a rush and listening to loud music to distract them from life. biggrin.gif

Who expects complete silence? We're gonna need names. biggrin.gif

The goal for me and others (who must remain nameless at this time) is the best COMPROMISE between cooling efficiency and noise levels. It's a sliding scale, not an either/or. If you want the 70+dB server room noise levels for a domestic system, that's your choice.

It's possible to build a powerful and reasonably quiet system. All fans are not alike in either cooling efficiency or noise. All coolers are not alike. We're here to discuss those tradeoffs, not to dismiss them.

The fun in being an enthusiast is building our own systems to suit our own tastes. My preference is to find and use the components that meet my low noise needs (<36dBA at load) while staying far below thermal throttling. My OC'd Xeon hexcore rig runs at 4.4Ghz on air with load temps at 59-60c at under 36dBA. At idle, it's below the 21dBA ambient threshold of the room. That's my compromise. What's yours?

My compromise is noise. I want full power and lowest possible temps 24/7. All of my fans run at 100% 24/7, I turn up the volume to compensate, and enjoy the hum when not in use. Silence is boring. We're all different.

Then you are no 'audiophile'. When I has audiophile-itis (maybe it was addition) the hardest part of building systems was getting all the hiss and buzz out of them .. and we had no fans or flying insects making noises. biggrin.gif
