Arctic Cooling Releases Arctic F Pro PWM Ultra Quiet High Performance Case Fans
The Swiss low noise cooling solution provider ARCTIC COOLING today announced the launch of the ARCTIC F Pro PWM case fans. They are in 3 sizes - 80mm, 92mm and 120mm. With the patented PWM Sharing Technology (PST), these new fans are surely the best choice for quiet enthusiasts.
CPU and VGA cards nowadays generate increasing amount of heat which leads to high case ambient temperature. Some users will use more case fans to cool down the case. However, this will produce more noise, and energy will be wasted as all fans run at full speed even after the case temperature is lowered.
Using the new ARCTIC F Pro PWM fan can solve these problems without any hassles. Firstly, with PWM signal, the fan runs at necessary speed according to the CPU load. Furthermore, thanks to the innovative patented PST function, up to 5 fans (including CPU fans) can be connected to the ARCTIC F Pro PWM fan. The speed of all the fans in this PST system is now centrally controlled by a single PWM signal via BIOS.
As a result, when the system load increases, all fans in the PST system will run faster to lower the case temperature. Likewise, when the load is low, fan speed will be lower at a necessary speed for sufficient cooling.
In conclusion, the advantages of having PST are:

In conclusion, the advantages of having PST are:
- Control the speed of different fans with only one PWM signal from the mainboard;
- Case ventilation can be achieved in a quiet and efficient way. More fans run slower at low load, which deliver sufficient cooling at a much quieter operation than before.
- Better energy saving as fans are not always at full load.

If your gonna be cooling a 4870 or OCing a 4850/4870 I'd recommend waiting a few weeks for the Twin Turbo Pro to hit retail..uses 2 x 92mm fans and a slightly bigger heatsink as well. ;)

Edit: Sorry for goin off topic soo much...let's just say 'YES...AC makes good fans.'...lol
And there was also this explanation : "A sone is an internationally recognized measurement of sound output. Sones translate decibel readings into numbers that correspond to the way people sense volume, and follow a "linear" scale, like inches. Sone readings offer quick sound comparisons for laymen and engineers."
And great looking fans, probably gonna put some of those in my next case :) But how do I put one of these as an intake-fan :wtf: ?
It says 0.3 sone. With my experience with AC fans, thats not even audible standing right next to the case.
I'm gettin some of these for my case :rockout:
Also keep in mind that the main selling point/feature of these fans (even tho they are very quiet w/ the fluid bearing technology) is their ability to run up to 5 fans using PWM to control fan speeds (thus the noise level) by adding a little signal amplifier that can put out enuff to regulate 4 more fans in the same way the CPU uses which is directly proportional to the CPU temp. After giving it a lil thought, I'd use the shared PWM from the CPU for, A: the cpu fan itself, B: The side intake fan and C: the rear exhaust. This would leave the front intake fan running at a constant speed for keeping the HDDs cool no matter what the CPU is doing so-to-speak, plus it helps balance the case airflow since the PSU fan needs a constant 'source of air' for the best results. Choosing a robust front intake fan (robust meaning a fan with a 'medium high' cfm rating) would be a wise move..make sure its a fluid bearing fan so it won't be too loud..they cost a bit more but worth every penny, if not for the lower noise then for the nearly doubled fan life. ;)
like I said I like the price of the Arctic Cooling fans and the bearing but not the dimensions.
