Good evening

I just bought this expandable and promising aio, and when I finish setting it up I notice my cpu temperature getting higher and higher (about a degree every 2 seconds).

Radiator fans are ok, block is placed perfectly, but the pump isn't pumping. I know this because there is no flow in the tubing nor noise coming out of the pump.
I tried turning on only the pump by jumping the psu and connecting it to a sata port but nothing.

Pump is connected via pwm and sata, setting it to max speed via bios does nothing, neither does alternating sata and pwm connectors.
I'd appreciate any input, thank you!!

Ps: I've built a couple of custom loops before, I'm pretty experienced with the whole thing but I don't wanna go trough the rma process unless necessary.
