I have a DVR unit that is over 10 years old and the cooling fan is going out. The current cooling fan is a T&T 6020H12S NF1 (0.16A/12VDC/3 wire). I cannot find this fan at all searching the internet, a couple similar ones but they are not the same dimensions.
I am not sure which configuration the 3-wire is set up for and the original equipment manufacturer is now defunct so I cannot request information from them.
In an attempt to replace this fan, I purchased this fan from cooler guys (DFH6020C12) and when I plug it in, nothing happened. No power, no movement on the fan.
Any suggestions on where I can purchase a suitable replacement for the existing cooling fan? Or how to determine the correct 3-wire configuration so I can ensure I get the correct fan?
