Processing: I was disappointed for the price, as the Finns do not even have the same distance, but it is not pathetic, just a matter of opinion.
Volume: The 0.1 sone, which I have read in another recession, although I think is unrealistic but it's not louder than my AC F12 Pro chassis fan. One should not hope allersdings that the PC thereby silently.
Cooling: If the fan is installed as in my case is the performance pathetic when I all recently rise up the side wall, and so the fan only times get air, then cools a 140W processor that runs on all 4 cores with continuous 100% to 55 ° at a room temperature of 27 °
Price: Apart from the processing (I think the Finns have to be parallel with a maschinel manufactured equipment for a glimpse) justifies the power price.
Conclusion: Who does not count very much on the processing and has at the level of the processor vent holes in the side wall, a lot of joy will have it.
For me it was a bad buy, unfortunately, because of the above reasons.
