Review on 🌀 Noctua NF-F12 iPPC-2000 PWM: Heavy Duty Cooling Fan for Optimal Performance and Cooling (120mm, Black) by Jacob Brasic

I ordered two of these nasty little rascals for my dual 120mm radiator on my computer case. The goods came as expected and were nicely packaged. The first installed without any problems, but I immediately realized that the problem was with the second. When I connected it to the fan controller I noticed that it is not a PWM connector like I ordered. For those who don't know what it is, it's the fourth pin that allows your computer to control the fan speed as the temperature rises or falls. This is important for my case to be able to control my CPU temperature under high load. I ordered two PWM fans and only received one, not the second. So when you order these fans, be sure to check the label on the box before you spend time taking your PC apart, only to discover upon removal that it is the wrong fan. For the money these fans are worth, you'd think the quality control would be a little tighter.
