the temperatures you're getting do seen to be a little hotter then usual, but not overly so. you could be using too much or too little paste indeed (or even paste that isn't very good).. but you also have to let the paste settle a little. The temps aren't anywhere near dangerous though, maybe just leave it for the time being.

The CPU could run hotter due to dust build up. Also you should use the same temperature displaying program because I'm running Core Temp and HW Monitor and they display different temps.

Core Temp: 55*
HW Monitor: 66*

What about the ambient temp, was it the same. the posotion of the laptop could impact the temps as well.

ambient temp is about the same, same room. I'm going to pull it out and reapply thermal paste again and see if it does anything.

On a laptop, the most likely culprit would be clogged air vents rather than the actual hsf....

Great suggestion. I took out the HSF this morning, gave all the vents a good blow and quite a bit of dust came out. Reapplied thermal paste and reseated. Sitting at 38 idle now :)

Thanks for all the help guys, would have just assumed it was the cpu getting hotter over time, now I know!

Never use a paper towel on your heatsink. It leaves paper fibres on the surface, which can totally fubar your thermal conductivity.

Paper towels do not deposit fibres unless they tear.

I'm no expert but it would be safe to say that over time a cpu certainly wouldn't run cooler. Lots of factors though.

Hey RLP06,

Do you remove your heatsink frequently after applying some compound? What kind of paste do you use? Do you use too little? too much? Do you try placing the heatsink on top of the CPU before attaching and move the heatsink around in half circles?

I believe over time that the cooling is not as fluid within a system. If you never open your case to clean inside, you risk of your fans developing dust/dirt. This slows down fans overtime and can cause problems. Cooling can be influenced many different ways.
