Quickly heating

[Darkiswhite]

Hi guys, I have a MacBook Pro 15 early 2011 with on Sierra.
Recently have noticed that while I surfing on the web with Safari as soon as i visit pages a minimum more heavy, like also the same Facebook for ex, after some sroll, video, right now the temperature of macbook start to rise.
I remember that this problem didn't happen in the past, also in the case I had more tabs open.
For you it's a normal behaviour, perhaps caused from the older of machine?

Open it up, the fans may be clogged with dust. It may also require the thermal paste to be re-applied given the age.

Thank for tip. The fans are already clean because I have open it recently. About thermal paste i don't know.
A little more of one year ago, the macbook it's were in assistance for the trouble that afflict the GPU on the early 2011 models.
In that occasion, it's were replacement the whole logic motherboard, however I believe that the status of thermal paste is good.

Unfortunately some mounth ago the GPU has stopped work, so i have follow a guide here on macrumors forum about use forced of integrated gpu.
The guide has worked, but i asking me if this could cause the problem of quickly heating.
