Request for guidance on laptop heating issues

[addverma]

Recently I observed that my Dell Inspiron laptop was running a bit slow. On observing the temperature using SpeedFan I found the following readings
1) CPU core temp 59 degrees centigrade  at 100% CPU Load.
2) GPU temp 57 degrees centigrade at 50% CPU load.
3) HDD temp 47 degrees centigrade
Now from what I know the average temperature should remain in the range of 40-50 degrees centigrade. While the temperatures that I am seeing are all in excess of that. So here are my questions
1) My laptop is in excess of 7 years old. Is it time to change the thermal paste? Will I get some improvements and decrease in the temperature readings?
2) The Fan speed being reported in Speed Fan is a steady constant 922 RPM. Should I look at getting a new heat sink for the CPU and a new fan for the laptop?
3) Does it make sense to get a liquid cooler for a laptop? Basically I want to extend the life as much as possible of this laptop.
    Any comments guys?

Is it an Intel or AMD CPU?

Generally laptop CPU's can take about 90 C before they start throttling. This isn't a bad thing for the hardware itself, but it's a noticeable performance drop for the user. Your temperatures are fine, you have nothing to worry about. Considering it's so old, have the drive replaced with an SSD (SolidStateDrive).

It is an Intel Core 2 Duo 1.66 Ghz. The reason I suspect it is the heat is for two reasons. One if I open the laptop from a shutdown state or in the morning then it is fairly snappy. However as the time goes the under side of the laptop get hot. Not enough to cook an omelet but still significant hot.

Secondly Even I put it to sleep or keep only one instance either of Firefox/Chrome or Open Office or Thunderbird, I still see the same behaviour.

I believe it is throttling because in system properties one core is listed as 1.66 Ghz while the other is listed as 966 MHz. This did not happen previously.
