Decibels are on a logarithmic scale, so every ten decibels has twice the apparent audio volume. But air is compressible, so sound sources don’t stack up as neatly. Ten times the source energy is needed to double sound pressure, and a drop of 3 dB is similar to reducing the source energy by half. With that understanding, we were pleased to see a 5 dB drop in the NH-L12’s noise level accompany the installation of its included resistor wires.

Zalman’s CNPS8900 Quiet similarly impresses us by making very little noise at full speed, and a look back at the thermal charts shows that its 51° over ambient result is very close to the low-speed NH-L12’s 49° over ambient.
A temperature reduction of 50% is a cooling improvement of 100%. To rate improved cooling with a higher percentage score, we divided the stock Intel baseline cooler’s temperature by the actual temperature of each competing solution. We then divided each cooler’s actual noise level by the reference cooler’s noise level to put noise on a direct scale, since the higher denominator produces a lower dividend.

The SilenX EFZ-100HA2 had a 10° advantage over the bundled Intel cooler, yet it's noisy enough to finish worse than the stock solution in a cooling-to-noise comparison. Zalman’s CNPS8900 Quiet takes top honors at full speed, while Noctua’s NH-L12 edges it out with the included speed-reducing resistor wires installed.

- The Best Cooler For Compact Systems?
Also, every mini-ITX motherboard is a little different. It would take some work, but it would be nice to see coolers cross referenced with different motherboards for compatibility. Just reading reviews it is pretty common to find one or two "Didn't fit my board" comments while other reviewers found the coolers to fit perfectly.
Do you mean vicious? Because I'm fairly sure the cycle wouldn't be a thick liquid.
It's good to see consistency
I'm using one from Titan that is really small: 107x70x12.5mm (official dimensions are incorrect) for the skived copper heatsink and can use 60mm or 70mm fans...i'm using a Titan fan that is 70x70x10.
Really compact....check my build at www overclock net
I i will add soon more pics and you will see something that is really small.
I was going to post precisely that.
I have one for my A8 8350 (100W) and it does a wonderful job inside a TT SD200.
And this is the CM cooler we're talking about: CM GeminII M4
Cheers!
anyone else think its ironic that Silenx's entry was that one of the loudest?

toms asked the vendors. may be coolermaster chose not to participate or didn't meet the set conditions. 8 vendors sent their samples according to the article.

I agree, these need to be tested in a tight case, preferably one where the low height is needed ( so no Prodigy, no HAF XB since those can fit normal tower coolers. ) The numbers here show what they can do in a normal ATX case, and that's a valid as some people don't like the torque of a 1kg sink hanging off their CPU. But since you were specifically asking for low-profile clearance for something like the Tiki and M8, these coolers need to be tested in that type of environment.
Guppy is right, you can't test every case and mboard combo, but if you could somehow finagle a run of three common boards and cases, it'd be very appreciated.
Ths silverstone may even pull ahead since it has the lowest mounted fan in the group, the air wil still be pulled through the heatsnink. the zalman should be able to pull some air from the sides if mounted next to the lid.
the 92mm fan on the silenx is its major flaw.
As an NH-D14 owner, I can't agree more. But the fan cowling color is not "pink". It's more of a very light pale beige... almost skin colored (typical non-tanned white person's skin). I honestly don't think Noctua could have chosen a more ugly color combo. Seriously. I took mine apart and painted it with matte (flat) black model paint (cowling, fans) and it looks awesome...disappears into the case if you will and doesn't look so obnoxious.
