Have two Y-cable for PWM 5,90 ordered and received. The Y-cables are high quality and well finished in typical Noctua. Furthermore, one must not forget that it is 4 pole PWM cable and these are anyway mostly slightly more expensive also. I have made the experience who buys cheap, it does often twice ;-) !!! I also have the 4 pin PWM extension cord from Noctua in use and can only say great quality. I guess whoever Zun quality schäzen know is right here and I can only recommend dehalb the Y-cable.
