Hello. I own an Asus R510DP for over 5 years, and a few months ago the laptop started to have extremely high temperatures (70-75 degrees). The laptop was purchased again. I have not given much interest in this aspect (temperature) but lately it has become a disturbing cooler that often runs at maximum speeds. I cleaned it (suctioned, blowing with a compressor), applied a new thermoconductor paste, I dismounted the side of the fan and cleaned it with a small brush. Often, especially when I study some PDF files or navigate to Google Chrome, the cooler starts running at high speed and the processor temperature reaches 66-70 degrees (for some simple actions). It slowly returns to 37-40 degrees but not for a long time. What could be the problem? We went into a couple of service but were not competent.
