Mac Pro led diagnostic

Hello, I have a problem with my Mac Pro, fan is doing a lot of noise, red light on motherboard and no screen.

I've clicked on the led diagnostic and found out that the led "SYS PG" "OVTMP CPU A" and "OVTMP CPU B" aren't lighted. I would like to know what those lights means. I couldn't find anything on internet yet...

If someone could help me that would be awesome, thank you

Mac Pro
