Have the San Ace H1011 and Nidec beta v TA450Dc B31256 tested please

This has kinda slipped to the side at the minute.

I still have all the fans, and am willing to test them all.

However, I need to find a way to effectively measure down to around 20dB - I can't find any sound meter which will go lower than about 35dB so I'm struggling

Any ideas?

compare them against a non variable sound? so we can adjust our speakers to how we know the test sound, and then we can test the variable sound (fan) ourselves

don't ask me what to use as a non variable sound though lmao

Am definately interested in your extended tests. There are few people actually testing fans like the Noctua NF-P12 compaired to the popular S-Flex series.

I know of a review of one of my local hardware sites: they tested 122 fans, though excluding the Noctua's as Noctua didn't provide testing samples unlike other brands. Though they didn't have the equipment as well to measure below 20 dB(A), they simple put the mic a lot closer. Instead of the normal 1 meter (3 feet), they tested at 10 cm (4 inch), which gave some sufficient readings. Those readings can be used to compaire fans in your own test. So perhaps it is something for you as well: just measure a lot closer.

If you can't find a way on how to measure, the other idea is to record it, along with some background noise.

I'm going to pick up a 30dB meter as soon as exams are over, and I'll also look into the actual frequencies of the tests.

30dB from close should be as low as is necessary

30 dB should be sufficient, especially if you have a background noise around 30 dB(A), which isn't too bad either. The following graph comes from the site I was referring to (Hardware.info, the test is only available in Dutch unfortenately though). I've looked it up: for the new measurements the sound readings were recorded with a meter capable of measuring down to 20 dB(A), though with an older test they used also a 30dB meter, located at 10 cm in an angle of 90 degrees with the base line being the center of the case fan.

Anyway, they came up with this graph:
Harware.info Sound production at maximum speed (12V):


In the latest test they used a meter capable of recording sound levels down to 20 dB(A) and came up with this is 2009. These measurements were made in a sound isolated box, though of course it is not as good as the sound readings from SPCR...

That's the plan
