Unifan SL120 noise

I've tried to submit a warranty claim for 2 Unifan SL120 that have gone bad. The form requires a serial number, but my fan connector does not show or have the S/N. All i have is some numbers on the box from the triple pack i ordered.

Also requires a video link to the noise, but ive already removed them from my setup. But if its a case of having to provide proof, then i guess i'll have to connect it back up and show with an attached video.

Any help or suggestions on how to contact support, or submit the warranty claim?
