Hey jmke, great review, but some reviews of heatsinks only mention this heatsink could hold my cpu at x degrees while the other keeps it at x+5degrees, so the first is better. Some other factors are also important for temperature, and thats the roomtemperature, and you should measure it and callibrate your findings to it. Or atleast say, that you measured it and it was the same. Obvious when your roomtemperature was 6degrees higher for the second heatsink, this second is the one that performs best. This temperature difference could appear when you conduct a series of experiments, and your hardware is still hot from the previous stress test.
Anyway, mentioning the environment-references makes it possible to compare reviews from different reviewers, or even from the same reviewer but at different times.

the heatsink used can also favor or disfavor a fan:

See at the performance of the tunic tower 120mm papst fan at lower sound=speed

I always mentioned room temp.... ?

reread and found it :-), i first only looked at the charts for interpreting, but room temp was at beginning of test setup.

once again great review

I also mentioned room temp in the charts right under the title:)

Very good review.

I have had good experience with a couple of fans that I can recomend for a review.

Aero cool turbine fan (1000/2000/3000) all the same exept for color.

and the new 140 mm aero cool Streamliner fan.

I have both pabst 4412 f2gl and Acusti fan dustproof fans, so I have compared the aero cool fans against the known best. The aero cool fans are not at the quality feel level of the two others and they have leds, so I was very skeptical to begin with. But their turbine blade profile with 16 blades intriqued me. The streamliner 140mm fan is the only one of its size on the marked, id dosent have the same turbine blade, but the specs looked interesting so I picked it up with the other ones.

In free air the turbine fan dident move more air than the pabst or the acusti fan at the same noise level, but when I put it in a restrictive case it began to stand out alot. It seems to be able to push air under greater pressure than the two others at a much lower noise level.

The 140mm streamliner is also very quiet, havent testet is so much yet, it has a big blind spot in the center and expel air outwards to the sides..so I think it will do best as a rear fan blowing out.

would be very interested in a comparative indept test of these two fans.

Thanks for a great site

aerocool turbine fan is on my next to do list, I'm waiting for new stock to arrive from taiwan :)

Nice review,

but little question about "where to buy".
When I look at Acoustifan its impossible to get a fan in Belgium without importing it and paying more than 35€ for a single fan.

Does anyone knows a store with reasonable prices for Acoustifan like the one used in the review. Preferable in Belgium.

I would email them directly and ask for resellers close to your location; also encourage them to find local distributors to work with:)

Why not go with a Papst GLL or Coolink?

They produce almost the same results at 12V like the AF at 7.5 so it's noise/performance is about the same, especially when you consider that there is always a small margin of error.

Even better and much cheaper (MRSP) when used as an exhaust at 7.5 is the Arctic Cooling one but I haven't found any yet despite I expect the demand for good and cheap 120mm fans to be very high.

You answer your own question with that.
AF is just at 7.5V where Papst is at its limit at 12V.
With AF its possible to cool just a little more.
