though it feels like the fan may not be blowing properly
This is a concern the CPU fan may be clogged with cat hairs, will the computer now function?
Normal everyday dust is an issue for computers and pets whilst we adore them they inadvertently add to the problem.
Tips for keeping your notebook cool include the following;
Always use the notebook on a flat, hard, even surface to allow air to circulate freely.
Do not use the notebook on soft furnishings such as pillows or cushions etc.
Avoid using the notebook with it resting on your lap as this also restricts the air flow.
If you live in a particularly warm/hot climate use a notebook cooler such as the example @ http://www.google.co...ved=0CGQQ8wIwAQ
Finally a regular clean out is a must.
