In my case, this just happened to be 5000. Then I went in 100 increments up until I lost the ability to turn on to 10% from a dead start, and went back down until it was reliable and quite. So I begin testing different PWM frequencies to see what it liked best (using code chunk below), starting at Q100, then Q500, and then increasing by 500 until I could get the fan to turn on from 0% to 10% reliably, with no 'blip' required, and with the least amount of noise - which yielded the outcome of Q5000. Upon testing it out, I noticed it wouldn't start to rotate until I hit about 75% throttle. The Razer PWM PC Fan controller features a low-profile design and magnetic backing, making it easy to install in tight spaces within your PC case.The other day I received my new parts cooling fan in the mail - got the soldering iron out and made it happen.
