(Temperatures at idle)
This is the new temperature reading after I changed the thermal paste.
Notice the new low reading especially on the GPU.
The reason is because Acer uses a thermal pad to conduct heat away from the GPU which is pretty inefficient.
After I changed the thermal pad and the original thermal paste, which is silicon based, the new temperatures are lower.
Originally the Processor Temperature is 60-70degrees.
Now it is 50-60 degrees at normal load 40-50 at idle.
Original the GPU is nearly 70 degrees now it is nearly 60 degrees.
10 degrees difference that is a lot.
(Temperatures while Gaming)
The temperature for the GPU used to exceed 100 degrees when gaming as some of you have experienced
Now it even barely hits 90 degrees (With elevated platform to allow airflow).
Hence I recommend if you want to game, please replace the factory thermal paste with high quality ones like Arctic Silver 5 or MX-2 if you are able to get one.
Arctic Cooling MX-2 is better as it is non-conductive, no cure time required and easier to apply.

Example of the thermal pad use to transfer heat from the GPU to heatsink
In the Acer Aspire 4530 Air enters the laptop through the bottom and exits through the rear so for better ventilation try to prop the laptop bottom on an elevated platform to improve thermal circulation.
