Hi, i bring you bad news.
I have the amilo xa 1526, wich is the same as yours but a little older, and i have exactly the same problem.
I have read about 1 million of forums, and i have found no solution.
i went to FSC workship in spain, technicians clean my fans ( wich never became dirty ), and put a drop of thermal paste on my cpu, then close the laptop and " perfect, your laptop like new ".
Nothing changes, tepmeratures the same as before.
I have tried underclocking, and altought not me, maybe you could reduce noise in standby mode, but never solve main problem.
I have tried all existing drivers... nothing.
Since not only cpus get hot you cant do nothing to cool down gpu, wich is for me the really problem.
Pay attention to avoiding your warranty, if you open your notebook you will lose it.
If you look a temperature/time plot ( with program you want ) you will realise there is no a 1 or 2 degrees problem, but much more.
A cooling pad dont solve the problem at all.
Our only chance is complain to fujitsu.
