I would recommend you take a look here and test this tool:

I done this myself a few times on other hdd's from the same vendor and it worked very fine but its always a risk you take so backup your things before you do this.

Btw yes your temp for the hdd is pretty high and you should try to make it lower. One quickfix is not to use your lap in the bed or where it cant get proper cooled but rather on a table or even better on a device similar like this...




Good luck!
