Question 3 red LED lights on the GPU and fans are spinning at max ?

[tiidus]

So, I am stupid and didn't deal with this earlier, but the problem I have is that my GPU has 3 red LED's on the entire time whenever I turn on my computer. Simultaneously, all the fans start spinning at maximum speed causing a really loud constant fan noise. This problem remains the entire time the computer is on. It's getting really annoying and I just wanna know what the problem is. Also, no PC parts have been overclocked before. The weird thing is that it has been normal (no red LED's and fans spinning) for like a couple of months), and after a couple of months this problem has occurred, so I'm really confused. Though I'm sure that the problem has occurred longer than not.
For my GPU, I did use 1 single connector that was split into 2 8-pin connectors, but I changed it to using 2 separate cables, but the problem is still here.

Here are my PC specs:

I use 2 monitors, but the problem still remains when I use one.
1st monitor: ASUS VG248QE (144 hz)
2nd monitor: Some ASUS monitor (60 hz)
Mobo: ASUS x570 pro-wifi
RAM: 32 gb corsair vengeance rgb pro 3600 MHz
CPU: Ryzen 9 5900x
GPU: EVGA RTX 3080 XC3 Ultra
PSU: 750W 80+ gold

If you need any more info, let me know. Thank you.

I also want to note that the PC works fine, despite this problem.

PSU: 750W 80+ gold doesnt really say much
those red lights are power supply issue
try with another power supply, if it doesnt help, RMA gpu
