Hello, recently I have noticed my laptop cpu fan was spinning very fast.
The CPU is Intel Core i5 5200U.
I turn on the AIDA64 to see what is up and my cpu fan was on max, cpu cores on 72-74(load).
Today I dissembled the laptop and the fan is clean and there is no dust inside the computer.
I think it is the thermal paste.
What do you think?
72-74 degrees while it's in load isn't that bad actually. Yes you can also apply new thermal paste on the CPU that should help in cooling it down. If you're still not comfortable with the temp of your laptop, I would suggest using a cooling pad to help more in cooling down the laptop.
