Inconspicuous PWM wolf in sheep's clothing, ideal for CPU cooling

After much trying out different CPU fan / cooler combinations, according annoying grinding noises of brand new fans, different sizes, different volts I am now finally arrived in this fan of Scythe and what can I say?

I am fully satisfied, PWM set in the BIOS to Silent, which is manifested in my overclocked to 3.6 GHz, hard to taming and hot i7 960 CPU with a Thermalright Macho in Idle in 280 RPM and 50 ° C.
One or the other like 50 ° C occur much, maybe I still have to emphasize that this CPU very well with a grill (130W TDP) could be compared, in view of this and that this was overclocked to 3.6GHz, these values ​​are amazing, especially the aspect "to create an air-cooled possible soft and flexible system" worked perfectly.
I'm sure that a current CPUs running (eg Haswell or Ivy Bridge = TDP up to 90W) with this fan with perfect temperature values, absolutely silent even under full load.

Speaking of flexibility, what is this fan especially distinguished his formidable range of 200 RPM to 1300 RPM, which (if the motherboard supports the well) brings out with PWM the optimal result for me depending on CPU load. So I can each one PWM connector on its motherboard finds these fan to 100% recommend as one of the best CPU fan, I for example can not be said of many Thermalright or preinstalled casing fans.

I use only on Scythe fan, I'm just happy with this, but the 14cm fan from be quiet, for example, are operated with 5V, also very good.
