I owned a Dell laptop of 3 years old. The information is as below:
Model: Inspiron 15R SE 7520
OS: Windows 10 HSL build 1511
CPU: Intel® Core i5-3210M CPU @ 2.50GHz
RAM: 4 GB DDR3 1600 MHz
HD: 1 TB 5400 rpm
This laptop is mainly for Office, Facebook, and occasionally 3D gaming. I recently heard from my friend that we should periodically renew the thermal compound of laptop CPU to ensure performance and overall machine lifespan.
I wasn't sure if my laptop is considered to be overheating, so I download "SpeedFan 4.51" today to view my CPU temperature. Here is what I get:
1. Right after start-up, my CPU Core 0 is about 47~48'c, while Core 1 is almost always above 50'c and recorded at about 51'c. This was measured during night.
2. When during usage, with Firefox opened for Facebook, and BlueStack for whatsapp, the temperature (during noon) were around 56'c to 58'c for Core 0. while for Core 1 is about 57'c to 62'c.
3. When during gaming (RE Revelations 2), temperature for Core 0 increased to about 56 ~ 64'c, while for Core 1 is about 60 to 66'c.
What do you think about these temperature? Should I have my laptop internal components cleaned and the thermal compound renew?
***Laptop Service History****
Motherboard was replaced twice, with the last service just about few days ago. Service reason was due to faulty motherboard as a result of unstable voltage supply from power source.
