The sense pin is a ground wire.

Hi all,

I want to start some experiments with TEC- modules. I bought some pci-e 6-pin extension cables to power the 2 TEC's and now I want to ask if it is safe to solder the 3 (2) 12v cables and the 2 ground cables with the sense pin together. I heard that the sense pin is just another ground connection, but I don't want to blow up my psu. It's a seasonic prime 1000W.

Thanks @jonnyGURU, I wasn't sure about that. The TEC's should support my existing loop to reach slightly sub ambient temperatures and are cooled by their own loop.
