See the thing is, I have a 4-year old ASUS K42JC:
Intel Core i5 450M
8GB DDR3 1600 MHz
Nvidia GeForce 310M (1GB)
Intel 530 SSD (128GB) and;
Windows 8.1 Pro (64-bit)
When I replaced the HDD that came with my laptop to an Intel 530 SSD just recently, I noticed that my laptop begins to heat up faster than with the HDD. The CPU temperature increases to 90 degrees Celsius when I play something like Counter Strike GO or whatever. But when I used to have the Hard Drive, it didn't heat up that fast.
