MSI GeForce RTX 4090 SUPRIM Liquid X Radiator Fan Problem

[raevy153d02dc]

I just recently got this card from Amazon along with a new Corsair HX1000i power supply.

The radiator and fans were too big to fit inside my case the way they arrived stock, so I took the fans off and mounted them on top of my computer case with the radiator screwed in under it.

It all seems to be nice and secure. I plugged the fans back in to the 4 pin connectors on the radiator and proceeded to install the new power supply.

When I turned on the system, I smelled and saw smoke, so I turned it off and looked inside the case. One of the 4 pin connectors coming off the radiator where one of the fans was plugged in had burned, and I am not sure why. The cables from the fans themselves seem fine.

I unplugged the cables from the radiator and instead plugged them in to the 4 pin fan connections on my motherboard, but only one of the fans is running and the other is stationary.

I have not changed anything regarding the card such as overclocking or messing with MSI Afterburner. Everything is stock, fresh out of the box.

What should I do here? Did the fan short out or break? Any idea why the cable on the radiator itself would burn?

Should I RMA the new card through Amazon or MSI?

If you can show picture what you have plugged and where and what's burned and damaged.

Here is a picture of the top of the case. Pardon the dust. As you can see, one fan is stationary.

Here is a picture inside. I plugged the two fans into the motherboard's 4 pin case fan slots. Only one fan is spinning. You can sort of see the damaged 4 pin connector coming from the radiator on the right.

And here is the cable. It doesn't show the exposed copper as clearly but as you can see, the sleeve burned off. The other cable appears to be fine.

Any idea why the cable on the radiator itself would burn?

From provided info don't know.

What mainboard brand and model is this and in which header the FAN was plugged in there?
