Hardware PS3 slim weird startup behaviour

[tray]

I replaced my thermal paste. After assemblying it I am getting this on startup. Any idea, I cannot find anything about this on google.

Can really see on the video what lights are blinking. Is it YLOD? Idk.

You should explain a bit more. I'm sure someone here can help with more information .
For instance why did you replace the paste to begin with?
