MacBook Pro 13" overheating

Hi everyone,

My MBP (late 2011 13") is overheating weirdly - when I start it up it heats up then cools then. When I go on firefox the fans go crazy then clams down... same thing when I first start watching a video on Youtube, it heats up and as I'm watching the video the fans start slowing down.

I Did an SMC reset, it helped but it seems to only be a temporary fix.

I also want to mention that my fans used to do a grinding noise, but it has now gone since I've swapped to an SSD HD.

Is the fan bust?

Regars,

Thomas
