I posted few days ago about my aurora overheating problem but got no real answer... So i decided to find the problem by myself and look what i found ...
My theory was that my pump wasnt working because 1 hose ( the out ) was really getting hot ( almost can't touch it ) and the intake was cold.
So i removed my entire watercooling systems
the inside pump liquid was full no problem here
The input right side... no problem
And finaly ... the problem the output of the liquid was complety blocked by that gelly thing
So i cleaned all this with alcool, putted new thermal paste on CPU and here we go 
Before
After
So i hope this thread will help someome because i did alot of search and found nothing that helped me.
And i got a question for alienware support wasnt the watercooling system was suppose to be maintenance free ??
This look like a bad quality watercooling liquid ! And its not old i bought my comp in june 2012 so warranty ended 1 month ago ...
