Review on ARCTIC F12 PWM PST CO - High-Performance 120mm Case Fan with Dual Ball Bearing, PST and PWM Technology - Grey by Matthew Riley

Great fans. I bought two to replace the old NZXT fans I had. They weren't necessarily bad, but they were getting old, had low RPMs, and I decided on something better to keep my computer running 24/7. Replaced front and side fans with these. I also bought a 140mm for a second exhaust fan as I had an empty vent that had room for one. Since I added these 3 fans, my computer's temperature has dropped significantly and it doesn't get as hot as it used to when playing heavy games. . I average 18 degrees while idling, while my CPU doesn't go above 50 degrees during heavy gaming and the case itself peaks at around 60 degrees. The PWM PST is a great addition, it allowed me to connect more fans than my motherboard. This way I have two exhaust fans connected to one cable and two supply fans connected to one, so the levels are always the same. I use SpeedFan to control the speed.
