Our recommendation for every Macbook and Macbook Pro that is older than 3 years is replace thermal paste (with nonconductive one) and cleaning internal fans. Our experience on many MacBook and MacBook Pro, their performance decreasing after approx. 3 years because of thermal issues. Those generally because of the thermal paste used in them not good after 3 years and dirt become solid on fans. We will post some updates on our post about this. After approx. 3 years, thermal issues are not only decrease your performance: We are nearly sure, thermal issues because of thermal paste and fan dirt are very effective on logic board and graphic card problems that finished with either logic board replacement or death Macbook or Macbook Pro. We are very suspicious on iMacs probably have same issues but not have any experience on them other than 5 iMacs we cleaned up and working better. We are recommend Artic Cooling Mx-2, non conductive thermal compound that last nearly 5 years.
