The next day tf2 played fine for a few minutes and then started lagging again. But league has stopped lagging and loading times are faster, could It have been an Internet problem? Also I there anyway to upgrade my fan?
I agree that your laptop could be suffering from a heat issue but don't discount software / drivers either. The fact you have cleaned things out and have some improvement can't cancel out other problems. You can't upgrade your laptops fans but have you considered a cooling stand.

Most laptops draw their air from underneath and chuck the hot air out the side or back. It's the closeness to desk (especially if you've lost your rubber feet) that doesn't help with decent airflow. The cooling stand will help.
I agree your system should be well capable of playing those games without lagging.
Intel® Core™ i7-2670QM processor 8GB DDR3 1333MHz memory
NVIDIA® GeForce® GTX 560M (3D vision) 1.5GB GDDR5 discrete graphics memory
You have to remember thought, although it's called a GTX 560M, it is not the equivalent of its desktop namesake and will not perform nearly as well.
Fire up Task Manager and check out the Performance tab with your computer idling. There should be little to no activity on any of your cores. In fact your overall CPU usage should be around 2% or less on your i7. If not you will have to go on the hunt for the offending program. Use Task Manager / Processes / Show processes from all users and find the one using you CPUs resources.
