The ARCTIC F Pro PWM fans outerperform other 80mm/92mm/120mm fans in the market. The patented PWM Sharing Technology (PST) regulates the speed up to 5 fans via BIOS. With efficient central cooling, the ARCTIC F Pro PWM fans offer excellent cooling and noise control performance for the system.
• Patented PWM Sharing Technology (PST) • Best noise-performance ratio • Patented fan holder eliminates the buzzing sounds • Patented vibration absorption • Fluid dynamic bearing extends service life • Compatible with screwless mounting
How does PST lower the temperature of the entire case?
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:
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

I bought this for my VRM cooler but I was rushing and didn't realize it was not easily attachable. I can't fault the fan for my ineptness. My roommate has a case with a very loud 80mm side fan and this fixed that!
A little thicker than normal fans, this is still a very good product. Installed in a Silverstone Sugo where space is a premium. Pushes a lot of air but amazingly quiet. I was short of 3/4pin slots on the motherboard but this fan allowed me to daisy-chain it with another.
