I applied MX4 on my 9 year laptop, no temp difference though!

Hello, I changed thermal paste for the first time on my 9 year old laptop but after 2 months of having this done, i still haven't noticed any temp improvement. The funniest part is that the temps remained exactly the same!

I wiped out of course the old thermal paste first using 93 degee alcohol (is it good by the way or i need more than 93?) which was hard as rock and applied mx4 to both gpu and cpu at size of a bean. Here are the pics before and after applying the new thermal paste.

  1. What is the nature of the problem - I mean is there a temperature problem evolved over time, or is it just you trying to run a more resource demanding game that just cause the computer to heat more than before?

    PRIME95 Maximum Heat 6min average temp:85
    Idle after prime95 temp:53

    Youtube video ~10min
    CPU:67-69-72-74-70-73-72-77-75-76-77-74
    GPU: 62 Min 67 Max

    Movie 6min
    CPU: 83c
    GPU: 72c

    League of Legends
    CPU: 83c
    GPU: 77c

    Not only those temps harm the components (cpu temp at least) but also the laptop sounds like a jet engine! Even on youtube videos.
  3. Maybe the fan has lost the capacity to handle your computer's cooling. You should start looking to replace that fan, or at least perform some kind of maintenance on it, also check that the fins of the heatsink are clean to allow airflow.

    No, that should appear as much higher temp readings.

    Also, I realized that OP is hunting _improvement_ of temperature reading. Well - the fan control algoritm/rule is the factor that control fan speed.
    Also, it's still unclear if that computers capability to self cool have deteriated over time or not. No other problem mention other than the actuall temperature readings - so I suggest - if no significant deteriation over time in terms of maximum temp readings or sudden power cutoff's - just let it be the way it is now.

    Do a visual check for dust inside the fan itself, and gently remove whatever dust trapped inside. The fan cover itselv may be dismounted in order to being able to remove all dust.
